报告介绍 Nanoscale materials and devices could play a unique role in biological and biomedical application due to their small size, minimal invasiveness, multifunctionality, and enhanced biocompatibility. In this talk, I will focus on discussing our recent progress of developing novel nanoscale field-effect transistor (FET) based devices to measure transmembrane potential change from inside living electrogen...

报告介绍 Abstract: There are many degenerate ground states in the geometrically frustrated spin systems, which can produce novel states. I will introduce an extremely frustrated lattice-Triangular Kagome Lattice (TKL). We obtain the exact solutions for the Ising model, Quantum+Ising model, and Dimer model on the TKL. The rich phase diagrams are found. Especially a topological phase - Kagome loop gas is found...

报告介绍 报告摘要： Mechanical stability is an important concept in fields ranging from civil engineering to physics and biology. In 1864, James Clerk Maxwell constructed a theory for the mechanical rigidity of frames composed of straight struts connected at points. Isostatic frames in which the number of degrees of freedom is equal to the number of constraints are of special interest. They are rigid but the...

报告介绍 报告摘要： The search for novel topological states of matter, where the quantum phase is characterized not by an order parameter but by some underlying topology, has been the focus of extensive studies since the discovery of the integer and fractional quantum Hall effects in two-dimensional semiconductors. These studies not only improve our understanding about topological states, but also have impor...

报告介绍 Abstract: Here we build the bridge between spin measurements and spin dynamics in driven systems. First, we analyze the physical meaning of a possible experiment aimed at the simultaneous measurement of two non-commuting spin components. We demonstrate that switching of a strong spin-orbit interaction in a solid or in a cold-atom system for a short time simulates a simultaneous von Neumann measureme...

报告介绍 AbstractAs the semiconductor device continues scaling down, conventional Flash memory is facing more and more bottlenecks and will be very difficult to go through 16 nm node. According to the white paper of ITRS 2010, STT-MRAM and RRAM are thought as the most promising technologies among various emerging non-volatile memory concepts, and are worthy to put additional focuses on research and developme...

报告介绍 Abstract:On account of high electron density, the Coulomb interaction in metals is efficiently screened on the length scale of interatomic distance and the time scale of inverse plasma frequency, i.e., typically in the sub-femtosecond regime. Nevertheless, transient excitonic interactions have been invoked in the interpretation of optical spectra and electron dynamics in noble metals. We explore the...

报告介绍 The presentation starts as the discussion of the solid-state laser technology, especially the ultrafast and high power laser systems, covering the topics, e.g. the cavity mode phase-locking, chirp-pulse amplification scheme, laser architecture and components etc. It will also address the application of the high power laser for the plasma science towards the thermonuclear inertial confinement fusion ...
