报告介绍 摘要：Recently, a new class of topological states has been proposed and experimentally realized. These topological insulators have an insulating gap in the bulk, but have topologically protected edge or surface states due to the time reversal symmetry. In two dimensions the edge states give rise to the quantum spin Hall (QSH) effect, in the absence of any external magnetic field. I shall review the ...

报告介绍 完整报告题目:  Quantum manipulation of topological qubits by quantum tunneling effect – new way towards fault-torrent quantum computation报告摘要： The degenerate ground states of topological order (the so-called topological qubits) are used as the protected code subspace to build a quantum computer by tuning their quantum tunneling effect. We study quantum tunneling effects of the topolo...

报告介绍 摘要：Topological order is a new type of quantum state beyond Laudau paradigm. Recently, many different systems with topologically ordered ground states on spin model (we call them symmetry protected topological orders) were found. How to classify symmetry protected topological orders and how to describe the quantum phase transitions between them (topological quantum phase transitions)? What's topol...

报告介绍 Abstract：The cluster-based nanostructures with quantum properties become one of hot topics in current nanoscience and nanotechnology. Following are a few examples related to the research work in our group.1) Quantization of surface phonon modes of Si clusters; 2) Long lifetime photolumicescence of silicon cluster-assembled nanowires; 3) Conductance resonance in gold cluster-assembled nanostructures...

报告介绍 Much of the excitement about graphene, a single atomic layer of carbon, arises from the fact that electrons in graphene behave as massless "relativistic" particles (Dirac fermions) with an effective speed of light equal to c/300. This has led to a number of profound discoveries, as well as a global “gold rush” searching for new physics and device applications. In this talk I wi...

报告介绍 Current trends in pharmacology and physiology employ the idea that collective structural motions participate in protein folding and function, however there is considerable controversy as to whether these motions exist and if rather dynamics are entirely determined by driven Brownian motion. The role of large scale collective motions in protein picosecond dynamics is investigated through terahertz (T...
