报告题目：Discovery of Topological Materials
报告人：Prof.Binghai Yan(Department of Condensed Matter Physics, Weizmann Institute of Science)
The concept of topology was introduced to physics to understand the unique behavior of materials, which was celebrated by the Nobel Prize in 2016. Over the past decade, the field of topological states has boosted frontline research in condensed matter physics. It is witnessed that the prediction and discovery of topological materials have stimulated the rapid development of this field. In this talk, I will first overview the general concepts of topological states. Chemistry insights are found to be rather helpful to discover topological materials and to realize beautiful concepts in physics. For example, the topological Weyl fermions were recently discovered in realistic materials with topological Fermi arcs on the surface and exotic transport phenomena in the bulk.
Binghai Yan is an Assistant Professor at the Weizmann Institute of Science in Israel. After completing his Ph.D. at Tsinghua University in 2008, he worked as a postdoc at Bremen University and later at Stanford University. He was a group leader in the Max Planck Institute for Chemical Physics from 2012 to 2016, assuming his current position at Weizmann in 2017. He was awarded the ARCHES Prize in Germany in 2013, and the Israel Physical Society Prize for Young Scientists in 2017. He is theoretical physicist and currently interested in solid-state materials that exhibit topological properties.
