主讲人简介/Biography:

Binghai Yan is an associate professor in the department of condensed matter physics at the Weizmann Institute of Science, Israel. After completing his PhD 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 in Dresden during 2012-2016 and started his current position at Weizmann Institute since 2017. He was awarded the ARCHES Prize in Germany in 2013, the Israel Physical Society Prize for Young Scientist in 2017, and recognized as a Highly-Cited Researcher during 2019-2021. He is a theoretical physicist and currently interested in topological materials and topology-induced phenomena.

讲座摘要/Abstract:

Topological quantum materials have been extensively studied in recent years. After introducing the band structure topology and related materials, I will talk about novel electric and optical phenomena emerging in quantum materials caused by topology. For example, Weyl semimetals can exhibit anomalous Hall effect (AHE) due to the monopole-like Berry curvature and also an exotic nonlinear AHE due to the Berry curvature dipole. Further, we found that magnetic quantum materials exhibit exotic optical responses, for instance, a giant photocurrent caused by the quantum geometry beyond Berry phase.
