报告介绍 报告摘要：　　The discovery of topological insulators has created a revolution in condensed matter physics and materials science that has far ranging implications over coming decades. I will first introduce a simple way to understand the essential ideas of topological insulators: band inversion and symmetry protection. I will then generalize the ideas to experimentally feasible superconducting syste...

报告介绍 Abstract:　　Multiferroic and magnetoelectric materials have attracted renewed attention since the magnetic orders breaks the spatial inversion symmetry and give rise to a ferroelectric state with a macroscopic polarization[1].The frustrated nature of the magnetic state in multiferroic MnWO4 is the reason [2] for its extreme sensitivity of the ferroelectric/magnetic orders to small perturbations in ...

报告介绍 报告摘要： 在电路理论中，电阻器、 电容和电感是三个基本元件，分别由四个基本电路变量（电荷、电压、电流、磁通）两两之间的线性关系来定义。基于对称考虑， 1971 年 Leon Chua提出应该存在第四种基本电路元件， 由电荷和磁通之间的线性关系来定义。由于他未能找到一种真实的器件直接联电荷和磁通，Chua做了一个数学变换，得到一种具有非线性电流-电压关系的器件， 称为忆阻器，并把它当作第四种基本电路元器件。在此，我们指出忆...

报告介绍 报告摘要： Determining the total structures of nanoparticles constitutes a major goal in nanoscience research. Gold nanoparticles are particularly attractive due to their extraordinary stability and elegant optical properties. A prerequisite to total structure determination is to obtain atomically precise nanoparticles, which had been a major challenge in the past research and thus hampered the purs...

报告介绍 报告摘要：　　Breakthroughs in energy conversion and storage technologies are desired throughout the world due to the ever-growing demand for energy.  Supercapacitors, as important supplement to batteries, offer much higher power density but with limited energy density.  Hydrogen-air fuel cells, on the other hand, are environmental-friendly but expensive alternatives to existing power supp...

报告介绍 报告摘要：Uniaxial materials whose axial and tangential permittivities have opposite signs are referred to as indefinite or hyperbolic media. While hyperbolic responses are normally achieved with metamaterials, hexagonal boron nitride (hBN) naturally possesses this property due to the anisotropic phonons in the mid-infrared. Using scattering-type scanning near-field optical microscopy, we studied po...
