摘要:

The 2016 Nobel prize for physics was a grant celebration of our understanding of topological phases and transition, part of which dates back to pioneering work of David Thouless and his collaborators when I became a graduate student of him 36 years ago. I was fortunate to be able to wetness and even participate the development of this topological theory of Chern insulators at the beginning of my career. In this talk, I will give an `inside look' of the topological Chern numbers, not only from my personal perspective, but also concentrating on its physical content, the Berry curvatures, to see how such topological and geometrical concepts have transformed our view of solid state physics.

专家概况:

牛谦教授现为美国德克萨斯大学奥斯汀分校Trull Centennia讲席教授、北京大学国际量子材料科学中心讲座教授,入选国家千人计划与美国物理学会会士。牛谦教授通过拓扑思想与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。 现已发表学术论文247篇,其中75篇Phys. Rev. Lett.、3篇Science、5篇Nature及其子刊, Review of Modern Physics, Physics Today、 Physics World各一篇,在国内外学术会议上作邀请报告340余次。
