Lee Hsun Lecture Series

Topic: Topology in magnetic systems

Speaker: Prof. Zi Qiang Qiu
     Dept. of Physics, Univ. of California at Berkeley,

Time: 15:00-17:00, (Mon.) Jul. 23rd, 2018

Venue: Room 468,Lee Hsun Building, IMR CAS

Abstract

Great advances have been made on magnetic nanostructure research since the discovery of Giant Magnetoresistance (2007 Nobel Prize in Physics). Two subjects have emerged among many frontier research directions: non-collinear spins and spin dynamics.  In this talk, I will give an overview of the non-collinear spins.  I will start by reviewing some interesting historical stories regarding topology in mathematics and physics, and then introduce the concept of topology in two-dimensional magnetic systems. Finally, I will discuss our recent results on magnetic vortices and skyrmions.

Professor Qiu Ziqiang graduated from the Department of physics of Peking University in 1984. He received his PHD in the Department of physics of Johns Hopkins University in 1991. He carried out his postdoctoral research at the Argonne National Laboratory in the United States during 1990-1993. He became an assistant professor and associate Professor since 1993 and was promoted to be Professor in 2005 for the Department of physics, University of California at Berkeley. His main research interests are magneto-crystalline anisotropy regulation, magnetic domain structure regulation and the preparation and regulation of topological magnetic structure in single crystalline thin film. He has published more than 120 academic papers in international famous journals such as, Nature, Nature Physics, Nature communications, Phys. Rev. Lett., Phy. Rev. B etc. In 2010, he was promoted to be the research Fellow of American Physical Society. Until Now, he has won many important awards including Young Investigator Award from Oversea Chinese Physics Association, Outstanding overseas academics of the Chinese Academy of Sciences, DOE BES/MS Award for Outstanding Scientific Achievement in Solid State Physics, AT&T Award of Research for Universities, Hellman Fellow Award, Outstanding Performance Award of Materials Science Division, Lawrence Berkeley National Lab etc.
