Research Interests

In the last five years, my research effort has been concentrated on formulating and finding various geometric and topological effects in condensed matter.  Most importantly, we have now developed a semiclassical theory which is accurate to second order in electromagnetic fields.  A host of new geometric and topological effects can now be identified in phenomena beyond linear response.

美国德克萨斯大学Trull Centennial教授,量子材料中心客座讲席教授

 

简历:
1981年北京大学物理系毕业,1985年获美国华盛顿大学(University of Washington )理学博士。

 

主要研究方向:
几何相位,拓扑效应,量子输运,纳米结构和量子器件,超冷原子气。

 

过去的主要工作及获得的成果:
通过拓扑思想和几何相位的系统性研究,对凝聚态基础理论做出了突出贡献,长久地影响了量子霍尔效应的研究,奠定了绝热输运和电极化理论的基础,复兴了反常 霍尔效应的领域,建立了轨道磁化的新理论,也推动了自旋霍尔效应的探讨。在当今丰富多样和越来越专门化的凝聚态物理中,这些拓扑思想和几何相位提供了一个 统一视角,在教科书的层次上修正了凝聚态基础理论。 由于这些工作,人们对绝缘体概念有了更丰富的认识,对金属和半导体中的电子动力学有了更深刻的理解,也对材料性质的计算有了更有效的方法。
