Jeff has a new paper published on Nature Reviews: Chemistry!
Chemists generally believe that covalent and ionic bonds form much stronger links between atoms than the van der Waals force does. However, this is not always so. We present cases in which van der Waals dispersive forces introduce new competitive bonding possibilities rather than just modulating traditional bonding scenarios. Although the new possibilities could arise from any soft–soft chemical interaction, we focus on bonding between gold atoms and alkyl or arylsulfur ligands, RS. Consideration of all the interactions at play in sulfur-protected gold surfaces and gold nanoparticles is necessary to understand their structural, chemical and spectroscopic properties. In turn, such knowledge opens pathways to new chemical entities and innovative nanotechnological devices. Such experimentation is complemented by modern theory, and presented here is a broad overview of computational methods appropriate to fields ranging from gas-phase chemistry to device physics and biochemistry.

Single-domain ferromagnets independent of its size and their potential applications

M.-H. Whangbo

Department of Chemistry North Carolina State University Raleigh, NC 27695-8204, USA


The feasibility of a single-domain ferromagnet (SDF) based on uniaxial magnetic ions was examined. For a noncentrosymmetric uniaxial magnetic ion of magnetic moment m at a site of local electric dipole moment p, we examined the nature of the magnetoelectric interaction between m and p in terms of analogical reasoning based on the Rashba effect and density functional calculations to find that m and p prefer an antiparallel arrangement, predict that Fe-doped CaZnOS is a single-domain ferromagnet like a bar magnet.

The possibility of using a group of quantum bits that act collectively as a bit (hereafter, a group bit or a gbit, in short) was considered. A promising candidate for a gbit is a SDF independent of its size, which can be prepared as a magnet of well separated uniaxial magnetic ions at sites of no electric dipole moment with their uniaxial axes aligned along one common direction. When magnetized, the uniaxial magnetic ions of such a magnet have a ferromagnetic arrangement and the resulting SDF becomes a gbit with its two opposite moment orientations representing the |0ñ and |1ñ states of a bit. Several 2H-perovskites satisfy the requirements for becoming such SDFs.

人类对物质不同表相的理解,始于水、蒸汽、冰。由蒸汽到水的凝聚过程定量理解首先由范徳瓦尔斯(van der Waals,1910年诺贝尔奖得主)发现。但是3维固体的融化过程,始终让世人困惑。我们在解释2维融化和相变方面的研究使我们获得了2016年物理学诺贝尔奖。朗道(Lev Landau,1962年诺贝尔奖得主)发现,1维情况下,没有固体融化—没有相变。朗道用对称性破缺和长程序理论对物质进行分类,这给了我们理解许多物质本质,包括物质的磁性本质,一个有力工具。但是朗道理论的限制过于严格,长程顺序并不是固体最根本的属性,剪切刚度才是。在2维,邵勒斯(David Thouless)和我证明了可用拓扑缺陷的结合和分解来描述融化过程。这一发现将提高我们对很多物质的认识,包括:超流体氦薄膜、磁铁、液晶和量子自旋链。

报告题目:Unidirectional allostery in the regulatory subunit RIalpha facilitates efficient deactivation of protein kinase A


报 告 人:Cong Guo 博士 (Florida State University)

报告时间:2017年 6月 5 日(周一)09:30


邀请人:Jeffrey Reimers,任伟


Activation and deactivation of protein kinase A (PKA) are triggered by cAMP binding to and unbinding from two tandem domains of the regulatory subunit. Evidence indicates that both binding and unbinding of two cAMPs are ordered. Whereas sequential binding to the inactive holoenzyme complex is well studied, the cause of sequential unbinding from the regulatory subunit remains elusive. It appears related to the unidirectional allosteric communication between the two domains, although the mechanism for unidirectionality has been a mystery.  In this study we present a solution through molecular dynamics simulations. One of the two cAMPs acts as a bridge between the domains and thereby gates interdomain communication. Directionality of allostery can facilitate PKA deactivation and may have broad functional importance.

Metallic and semi-conductor nanoparticles are now well known as species that offer specific characteristics of capital importance in a multitude of fields. With their extremely large surface areas, they are used for innumerable applications such as pharmacy and cosmetics, catalysis, bio-sensing and emission amplification. Of the many techniques of fabrication employed, most involve either colloidal syntheses, laser assistance or in-situ thermal formation. For many applications, the nanocrystals must be embedded in glass or glass-ceramic matrices, and often combined with active ions or other species.


Fig. 1 Size evolution for laser induced SnO2 NCS

Obvious questions, therefore, include the actual structure and size of the nanocrystals and the nature of interactions between them and other active species present. Questions might also cover the effect of the nanocrystals on the host matrices, as well as how the matrices might affect the nanocrystals. Among the spectroscopic techniques used to respond to these questions are micro-Raman and IR vibrational spectroscopies, as well as UV-visible and luminescence techniques. Results thus obtained are then combined with data obtained using other physical-chemical techniques such as X-ray diffraction, XPS and SEM, in order to discuss structural changes.


In this presentation, examples will be given of the determination of the structure and size of free-standing PbSe NCs prepared by colloidal syntheses. In another work, the growth of in-situ thermally created SnO2 NCs is followed spectroscopically. Luminescence results show energy exchanges between them and dopant rare earth ions, as well as the location of the ions with respect to the NCs.


Finally an example is given of local trails of ZnO NCs created within silica matrices using pulsed UV-laser excitation. Micro-Raman studies show, however, that the areas of the matrix close to the NC trails are damaged, because of the creation of a large population of non-bonding oxygens. In addition there is a dispersion of NCs outside the trails.

Activating WS2 Basal Plane for Highly Efficient Hydrogen Evolution

Electrocatalytic water splitting is a plausible alternative for hydrogen production with high impact in energy generation. The transitional-metal dichalcogenides (TMDCs), such as molybdenum disulfide (MoS2) tungsten disulfide (WS2), have been greatly expected to be efficient and noble-metal-free catalysts for hydrogen evolution reaction (HER). However, the HER activity can’t take place on the inert basal plane, which has a very large surface area is an intrinsic advantage for TMDs. By introducing sulfur (S) vacancies on the surface of WS2, it is found that the inert basal plane of WS2 turns out to be active for HER. The HER activity is extremely enhanced due to the binding between hydrogen and exposed W atoms. The hydrogen adsorption free energy indicates that the basal plane exhibits high performance in HER with a wide range of S vacancies concentration. Furthermore, the straining of surface with S vacancies has a trend to decrease the hydrogen adsorption free energy. Thus, it’s more flexible to achieve the highest efficiency of HER by joint manipulation of S-vacancies concentration and surface strain.

Title: First-principles study of complex halide scintillators for radiation detection
Current demands for cost-effective and high-performance scintillators have led to a discernible shift from simple binary halides (e.g., NaI, CsI) toward host compounds that are structurally and electronically more complex. Eu-doped SrI2 is a prominant example. Despite its advanced properties, improvements are needed for extensive deployment at low cost. Codoping techniques are often useful to improve the electronic response of such insulators. Using first-principles based approach we report on the influence of codoping with aliovalent and isovalent impurities. We find all codopants induce deep levels, show amphoteric character, and may bind with I-vacancy forming charge compensated donor-acceptor pairs. Lack of deep-to-shallow behavior upon codoping and its ramifications will be discussed.
We have studied another set of stable orthorhombic phase of ternary halides containing iodides, e.g. CsCaI3 and KCaI3. One objective is to explore the structure induced difference in scintillation properties. Interestingly, we found distinct behavior in carrier mobility and induced defect levels within these two compounds, which may explain the low light yield in CsCaI3.

The bulk photovoltaic effect in polar oxides for robust and efficient solar energy harvesting

Andrew M. Rappe
University of Pennsylvania

Solar energy is the most promising source of renewable, clean energy
to replace the current reliance on fossil fuels. Ferroelectric (FE)
materials have recently attracted increased attention as a candidate
class of materials for use in photovoltaic devices. Their strong
inversion symmetry breaking due to spontaneous polarization allows for
excited carrier separation by the bulk of the material and voltages
higher than the band gap (Eg), which may allow efficiencies beyond the
Shockley-Queisser limit. Ferroelectric oxides are also robust and can
be fabricated using low cost methods such as sol-gel thin film
deposition and sputtering. Recent work has shown how a decrease in
ferroelectric layer thickness and judicious engineering of domain
structures and FE-electrode interfaces can dramatically increase the
current harvested from FE absorber materials. Further improvements
have been blocked by the wide band gaps (Eg =2.7-4 eV) of FE oxides,
which allow the use of only 8-20% of the solar spectrum and
drastically reduce the upper limit of photovoltaic efficiency.

In this talk, I will discuss new insight into the bulk photovoltaic
effect, and materials design to enhance the photovoltaic efficiency.
We calculate from first principles the current arising from the “shift
current” mechanism, and demonstrate that it quantitatively explains
the observed current. Then, we analyze the electronic features that
lead to strong photovoltaic effects. Finally, we present new oxides
that are strongly polar yet have band gaps in the visible range,
offering prospects for greatly enhanced bulk photovoltaic effects.

Slush Structure and Dynamics in a Relaxor Ferroelectric

Andrew M. Rappe
University of Pennsylvania

Ferroelectrics are smart functional materials that interconvert
electrical and mechanical energy. As such, they are the functional
components of SONAR, ultrasound, smart cards, transducers, and
actuators. Ferroelectric materials undergo solid-solid structural
phase transitions between phases with aligned dipoles and randomly
oriented dipoles.

Incorporating quenched Coulombic disorder by varying the
charge of the ions on the lattice disrupts and changes the character
of this transition; instead of a sharp transition in a small
temperature range, these oxide alloys exhibit “relaxed” transition
over 100-200 K and are called “relaxor ferroelectrics.” In this talk I
will describe how a first-principles based multi-scale model can
reveal the dynamic and statically correlated motions of ions that lead
to relaxor behavior, and I will discuss their promise for
next-generation piezoelectric and dielectric material systems.

Nowadays, the urgent demand for new technologies has greatly exceeds the capabilities of materials research. Understanding the atomic structure of a material is the first step in materials design. Tremendous progresses have been made in crystal structures from first principles based on a variety of global optimization methods combing density functional theory (DFT) calculations. Nevertheless, it is still challenging to deal with complex systems such as organic crystals. Furthermore, recent experiments have revealed highly complex interface structures in different solids. The understanding of the atomic arrangements in the interfaces is crucial for the engineering control of materials properties on an upper level. In this talk, I will discuss the recent progresses in applying the evolutionary algorithm to study the organic crystal polymorphism and the structural phase transformations in metallic grain boundaries. The encouraging results so far suggest a major role of this approach in the prediction and design future functional and structural materials.

Photochemistry, spectroscopy and mass spectrometry of protonated
aromatics: gas-phase and liquid microdroplets
A/Prof Adam J. Trevitt
Laser Chemistry Laboratory, School of Chemistry, University of Wollongong, NSW, 2522
Photons initiate chemical action by exciting molecules to more active bound states or by breaking bonds to
create reactive products. Fundamental insights into these processes has led to a useful understanding of
atmospheric photochemistry (like haze formation), pin-pointed inefficiencies in organic-sensitized solar cells
and enabled targeted photodynamic therapies in biological systems. To make further inroads and master the
photochemistry underpinning these applications, our research group is engaged with the study of
photoactivation – in gas-phase isolation and in solution. This presentation will outline our recent results
concerning protonated N-substituted aromatics using ion trap mass spectrometry and a new microdroplet
mass spectrometry technique.
Two projects will be described:
(i) tunable UV-vis laser radiation coupled to a linear ion-trap for gas-phase action spectroscopy of ions.
Several protonated aromatic systems that are fundamental chromophores in many settings are probed
using UV photodissociation spectroscopy. These species include pyridineH+ and (iso)quinolineH+
chromophores. New insights into the stability and fate of their low-lying excited states will be
(ii) a unification of single microdroplet generation, laser photolysis and mass spectrometry for rapidacquisition
of liquid-phase action spectroscopy. Our single-droplet desorption strategy, shown in the
figure (ii) below, involves single droplets falling on a thin needle held at 2 kV. The subsequent
electrospray is sampled by a mass spectrometer. This is performed at 10-20 Hz, one droplet at a time:
one droplet (40 pL); one laser pulse; one spectrum. Solution-born photoproducts are detected mass
spectroscopically within milliseconds. Since there is no cross-contamination between droplets, laser
on/off statistics are rapidly obtained. Results probing the photochemistry of s- and p-type aromatic
radical systems and a novel liquid-phase action spectroscopy method will be discussed.

Computational Materials Design via Electronic Structure Engineering

Abstract: Materials properties are in principle determined by electronic structure. With the development of computer hardware and algorithm, now we can calculate electronic structure for a given material up to thousands atoms. It is well-known that introducing defect, strain, interface and doping in nanoscale materials will greatly modulate materials electronics functionality, thus allow us to tune materials properties. Our current research mainly focuses on computational design of nanosale materials for energy and electronic application in collaboration with experiment. In this talk, I will present our recent research progress on engineering materials properties via electronic structure engineering. Particular focus will be given on (i) how mechanical strain will modulate hydrogen evolution reaction activity, band gap and topological phase transition [1-3]; (ii) how van der Waals hetero-interface modify materials’ optical properties, chemical reaction, stability and charge separation[4-5]; (iii) how single atom doping help to convert carbon dioxide into alternative fuel cell [6] and H atom saturation turn Boron nansoheet into Dirac material [7] and surface O-termination on 2D Mxenes is functioning as catalytic active site for hydrogen evolution reaction; (iv) how defective boron nitride sheet become magnetics and halfmetallic [8] and defective graphene can actually act as catalytic active sites for enhancing electrochemical reaction [9].

Towards Generic Mathematical Descriptors for Structural Analysis and Their Applications in the Property Predictions for Molecular Crystals

The steady progress in the field of organic crystal structure predictions (CSP), exemplified by successes in the most recent international CSP blind test, has demonstrated great promise in using this computational tool in advancing our understanding in polymorphism. With global lattice energy exploring algorithms, the number of putative crystal structures generated is typically on the order between 10 to 100K, which poses a significant challenge in extracting structural patterns and thus generalizing useful chemical insights in an automated fashion. A more challenging task is how to correlate this structural information with the predicted physical properties, such as the charge transport parameters for organic crystals. The later is crucial for advancing computer-guided material designs. Unlike molecular conformation samplings in gas/solution phases, where a plethora of dimensionality reduction techniques had been developed to extract intriguing features from the energy landscapes, less had been developed for molecular crystals, due to a lack of generic and robust descriptor to represent molecular crystals ubiquitously.
Dimer synthons are the most widely used term in describing molecular crystals. Starting with the crystal structure landscape of a polyaromatic molecule, I will show how a simple set of Steinhardt bond order parameters can be applied to target pi-stacking motifs in molecular crystals, and hence to predict nearest-neighbouring transfer integrals for calculating electron mobilities. I will then discuss how a more agnostic fingerprint (SOAP) can be used to describe more extended structural features in molecular crystals, not only that it leads to near-identical structural classification by human inspection, but excellent predictions on charge mobilities. Finally, building on the formalism of many-body expansion for energy evaluation in molecular crystals, it will be demonstrated that how to design different ‘similarity kernels’ for highlighting structural similarities in molecular crystals at different ‘length scales’, which is particularly important for characterising hydrogen-bondings in molecular crystals.


Dr. Yang received his BSc in Nanotechnology with first class Honour from the School of Material Science and Engineering at the University of New South Wales in 2007.

His thesis focused on investigating the structural, electronic and transport properties of low-dimensional nanostructures, using DFT and Green’s functions.
From 2011 to 2013, he conducted his postdoctoral studies in the Organic Institute at Westfälische Wilhelms Universität Münster, Germany. His major research interests were on structural predictions and cooperative effects in non-covalent interactions in molecular systems. He is now a postdoctoral research fellow under the ERC-ANGLE grant at University of Southampton, working on crystal structure and property predictions for molecular crystals. His latest research interest is on developing agnostic descriptors and similarity kernels for analysing structural features in the lattice energy landscapes for molecular crystals..

High dielectric constant elastomers for electromechanical applications

Elastomers that respond to an electric field by changing their size and shape are of great interest for applications such as engines, optical devices, sensors, energy harvesters and artificial muscles, to name a few. Dielectric elastomer actuators (DEAs) are stretchable capacitors made of a thin elastic film sandwiched between two compliant electrodes. Upon application of a large voltage, the film expands laterally due to the electrostatic attraction between oppositely charged electrodes (Maxwell pressure). Widespread application of this simple working principle is still hampered by the large operation voltage of about 1kV required for commercial elastomers. A straight forward approach to reduce the operation voltage is to increase the dielectric constant of the polymer while conserving the mechanical properties and insuring low electrical conductivity. Two approaches towards this goal will be highlighted in this presentation; the first is based on composites with metallic fillers and the second utilizes dipolar functional groups covalently attached to the polymer.

Cyanine dyes were developed with a view to create extremely strong light-absorbers with narrow absorption spectra at specific wavelengths. They proved particularly successful as sensitizers in silver halide photography but also find applications in recordable optical discs, bio-labels and all optical devices.. Only little interest has been dedicated to the use of these materials as semiconductors, which however significantly widens the span of applications. Using choromophores with a high number of vinylene units allows producing thin near-infrared active films with extremely high optical transmission in the visible region. In this presentation, solar cell and photodide fabrication based on cyanine semiconductors will be highlighted and an outlook on future applications will be given.

“Ab initio properties for large molecules using fragmentation approaches”
It is still believed that ab initio quantum chemical methods are needed to reach chemical accuracy for many property calculations. However, the cost for many of the high-accuracy methods, such as the gold standard CCSD(T), remains prohibitive for all but small systems. For this reason, fragmentation methods are gaining in popularity. In this lecture I will describe some fragmentation approaches and various applications in which they can be used, especially the NMR of biological systems.


报告题目:Optomechanical many-body cooling to the ground state using frustration

报 告 人:Thomas Fogarty (日本冲绳科学技术研究所)



邀 请 人:陈玺 教授


We show that the vibrations of an ion Coulomb crystal can be cooled to the zero-point motion through the optomechanical coupling with a high-finesse cavity. Cooling results from the interplay between coherent scattering of cavity photons by the ions, which dynamically modifies the vibrational spectrum, and cavity losses, that dissipate motional energy. The cooling mechanism we propose requires that the length scales of the crystal and the cavity are mismatched so that the system is intrinsically frustrated, leading to the formation of defects (kinks). When the pump is strong enough, the anti-Stokes sidebands of all vibrational modes can be simultaneously driven. These dynamics can be used to prepare ground-state chains of dozens of ions within tens of milliseconds in state-of-the-art experimental setups. In addition, we identify parameter regimes of the optomechanical interactions where individual localized modes can be selectively manipulated, and monitored through the light at the cavity output. These dynamics exemplify robust quantum reservoir engineering of strongly correlated mesoscopic systems and could find applications in optical cooling of solids.

Density-Based Adaptive QM/MM Methods
Mark P. Waller,
QM/MM modeling has become one of the methods of choice for modeling macromolecular
systems. This is evidenced by the awarding on the 2013 Nobel Prize in Chemistry “for the
development of multiscale models for complex chemical systems”.1 However, one of the limitations
of QM/MM modeling is the traditional rigid partitioning of a given system into a QM and MM
region. For instance, this becomes problematic during QM/MM-MD simulations, as the initial
partitioning on the system eventually becomes invalid. There has been much work spanning more
than almost two decades on an adaptive variant, i.e. where the partitioning occurs during the
simulation. We recently wrote a clear and easy to follow review2 on the practical aspects of carrying
out adaptive QM/MM calculations.
Adaptive QM/MM methods use two types of partitioning criteria. Firstly, there are distance-based3
approaches, which are empirical in nature because the cut-offs must be fitted. Secondly, a number
based approach4, which enables a pre-determined integer number of molecules to surround the QM
core region. Our approach5 is to develop a method whereby no fitted parameters are needed to
partition the system, instead the system is analyzed and partitioned based on physical arguments.
This neatly circumvents empiricism, and makes the adaptive-QM/MM method more generally
applicable. Our new adaptive-QM/MM method is based on employing an auxiliary atom-centered
spherical density, which is analyzed to detect non-covalent interactions between the QM-core and
the rest of the system. If non-covalent interactions are detected between a fragment and any QMcore
atom, then the fragment is placed into the QM region. Based on this definition, all noninteracting
fragments are placed into the MM region.

报告题目:Majorana费米子和拓扑量子计算(Majorana Fermions and Topological Quantum Computation)

报 告 人:Chuanwei Zhang(张传伟), Professor of Physics, Department of Physics, University of Texas at Dallas



邀 请 人:张永平教授


Majorana fermions, first envisioned by E. Majorana in 1935 to describe neutrinos, often emerge as topological quasiparticle excitations of the underlying systems. Majorana fermions are intriguing because they are their own anti-particles and follow non-Abelian anyonic statistics. Although the emergence of Majorana fermions in any condensed matter or atomic system is by itself an extraordinary phenomenon, they have also come under a great deal of recent attention due to their potential use in fault tolerant topological quantum computation. In this talk, I will give a general introduction for topological quantum computation and Majorana fermions. I will discuss recent theoretical and experimental progress on the search for Majorana fermions in different experimental systems. I will highlight some contributions of my group in this rapidly developing field.

Inorganic-Organic Framework Materials: There’s Plenty of Room in the Middle

Prashant Jain (Los Alamos National Lab.)

The study of hybrid inorganic-organic frameworks is one of the most fashionable areas of materials science. This presentation will give a basic introduction to the field and focus on multiferroic aspects of our recent work on dense hybrid frameworks.

Multiferroics are rare materials with coexisting ferroelectric and ferromagnetic orders. Magnetoelectric multiferroics, where the two phenomena are coupled and can be manipulated by one another, are rarer and only handful of these materials are known. During past decade there has been a resurgence of this field, which has primarily been driven by the exciting technological applications of magnetoelectric multiferroics.. In this presentation, I will present our findings on single-phase multiferroic hybrid framework materials. In addition, I will also present our latest results on magnetoelectric and magnetodielectric coupling in these materials.

报 告 人:Joel S. Miller(犹他大学)
邀 请 人:柏跃玲
报告简介:Molecule-based materials exhibiting the technologically important property of bulk magnetism have been prepared and studied in collaboration with many research groups worldwide frequently exhibit supramolecular extended 3-D structures.  These magnets are prepared via conventional organic synthetic chemistry methodologies, but unlike classical inorganic-based magnets do not require high-temperature metallurgical processing.  Furthermore, these magnets are frequently soluble in conventional solvents (e. g., toluene, dichloromethane, acetonitrile, THF) and have saturation magnetizations more than twice that of iron metal on a mole basis, as well as in some cases coercive fields exceeding that of all commercial magnets (e.g., Co5Sm).  Also several magnets with critical temperatures (Tc) exceeding room temperature have been prepared.  In addition to an overview of magnetic behavior, numerous examples of structurally characterized magnets made from molecules will be presented.  Our groups has discovered ten families of molecule-based magnets, mostly organic-based, and have significantly contributed to the family based upon the Prussian blue structure.  Four examples magnetically order above room temperature and as high at 127 oC.  These will include [MIII(C5Me5)2][A], [MnIII(porphyrin)][A] (A = cyanocarbon etc. electron acceptors) as well as M[TCNE]x, which for M = V is a room temperature magnet that can be fabricated as a thin film magnet via Chemical Vapor Deposition (CVD) techniques.  A newer class of magnets of [Ru2(O2CR)4]3[M(CN)6] (M = Cr, Fe; R = Me, t-Bu) composition will also discussed.  For R = Me an interpenetrating, cubic (3-D) lattice forms and the magnet exhibits anomalous hysteresis, saturation magnetization, out-of-phase, ?”(T), AC susceptibility, and zero field cooled-field cooled temperature-dependent magnetization data.  This is in contrast to R = t-Bu, which forms a layered (2-D) lattice.  Additionally, new magnets possessing the nominal Prussian blue composition, M'[M(CN)6]x and (Cation)yM'[M(CN)6], but not their structure, will be described.  New physics observed from examples of organic-based magnet will be discussed.

Graphene grown on metal surfaces is an exciting field of solid-state chemistry and physics from different points of view. Technologically, this is the main and the most perspective way for the large-scale preparation of high-quality graphene layers of different thicknesses with controllable properties. The obtained systems might be used for many applications, like spin filters (in graphene/ferromagnet sandwiches), gas sensors, or in case of graphene/metal moiré structures as templates for the preparation of exceptionally well-ordered nanocluster lattices. Along with the practical view on these systems, investigations of graphene/metal interfaces gave rise variety of fundamental questions, e.g., regarding the nature of bonding between graphene and metal and the origin of modifications of the electronic structure of graphene in vicinity of the Fermi level. Basing on the analysis of a large amount of experimentally and computationally obtained band structures, we proposed a universal model, which allows one to describe qualitatively any graphene/metal system. All experimental observations such as doping, hybridization of the valence band states of graphene and metal, and gap formation can be understood in the framework of the approach.

She has a broad experience in the development and application of theoretical techniques for investigation of the electronic structure of a wide range of systems. She has co-authored more than 70 publications in peer reviewed journals.

Graphene on metals, which structure can vary from simple lattice matched to commensurate moiré structures, is an ideal system for different kinds of surface science experiments allowing to study many fascinating phenomena. Here we present several examples on the application of electron spectroscopy (NEXAFS, XMCD, XPS, ARPES) and scanning probe methods (STM and AFM) for the investigation of the electronic structure of these systems: graphene on lattice matched 3d ferromagnetic metals (Ni and Co) and on lattice mismatched 4d and 5d metals (Rh, Ru, and Ir). These combined approaches allow to understand the bonding mechanism at the graphene-metal interface, the main features of the graphene-derived electronic structure as well as the imaging contrasts in the scanning probe experiments. All experimental data are compared with the state-of-the-art DFT calculations that lead to the deep understanding of the observed phenomena.

ICQMS seminar:Quantum manifestation of transition-state control of state-to-state dynamics


(Quantum manifestation of transition-state control of state-to-state dynamics)

  :Dr. Hua Guo (郭华,University of New Mexico,美国新墨西哥大学)






The concept of transition state is a fundamental one as the activated complex plays a dominant role in kinetics. We demonstrate that the transition state also controls reaction dynamics, even at the state-to-state level. It is shown that there are two kinds of reactant modes. An active mode is strongly coupled with the reaction coordinate at the transition state, thus promoting the reaction by channeling energy into the reaction mode. As a result, its excitation has little effect on the product state distribution. The other kind of modes has very little coupling with the reaction coordinate at the transition state, hence behaving as a spectator throughout the reaction. The energy deposited in a spectator mode is sequestered during the reaction and transferred into the vibration of the product. These detailed quantum state-resolved information sheds light on the transition state control of reactivity.

(Confined linear carbon chains: Synthesis and properties)


  :石磊 博士 (维也纳大学)






  :赵新洛 教授



The extreme instability and strong chemical activity of carbyne, the infinite sp1 hybridizedcarbon chain, are responsible for its low possibility to survive at ambient conditions. We successfully synthesized extremely long linear carbon chains (LLCCs) inside thin double walled carbon nanotubes as nanoreactors and protectors. Their existence, structure, lengths and yield have been proved by Raman, HRTEM, STEM and XRD. The results show that the single-triple bonded LLCCs including thousands of carbon atoms have at least six new Raman peaks, some of which are even stronger than the G-band. The optimum growth conditions, for example, diameter of the host tubes, annealing temperatures and time were carefully studied. The interaction and charge transfer between the LLCCs and their host nanotubes were explored using resonance Raman, low-temperature Raman and DFT calculations. Furthermore, the band gap of the LLCCs was examined by resonance Raman spectroscopy. The results suggest that the band gap of LLCCs in the range of 1.8 – 2.3 eV is inversely proportional to their lengths, which is also perfectly consistent with our DFT calculations.

Sometimes, nature illustrates the abstract ideas of physics and mathematics in beautiful ways, and the ideas can be brought to life by simple demonstrations. My seven wonders—each with a deep underlying idea—include the great moon-driven river wave, light interference magnified in rainbows, quantum twists and turns, and the color of gold.




报告题目:旋度力及其外延(Curl forces and beyond)


  :Dr. Sir Michael Victor Berry (英国布里斯托尔大学)



  :陈玺 教授




Forces depending on position but which are not derivable from a potential, that is, forces with non-zero curl, give rise to dynamics that is not Hamiltonian or Lagrangian, while also being non-dissipative. Noether’s theorem does not apply, so the link between symmetries and conservation law’s is broken. The physical existence of curl forces has been controversial and the subject of controversy among engineers. But an example is familiar in optics: force on a dielectric particle in an optical field. Motion under curl forces near optical vortices can be understood in detail, and numemrics reveals a new kind of chaos. The full series of ‘superadiabatic’ correction forces is derived, leading to an exact slow manifold in which fast (internal) and slow (external) motion of the particle is separated.
