The recipient of 2017 Lee Hsun Lecture Series—Lee Hsun Lecture Award, Prof. Ziqiang Qiu from University of California at Berkeley visited Institute of Metal Research, Chinese Academy of Sciences (IMR, CAS) from June 21 to 24, 2018.

During the visit, Prof. Qiu delivered a lecture entitled “Topology in magnetic systems”. In his lecture, he gave an overview of the non-collinear spins by reviewing some interesting historical stories regarding topology in mathematics and physics and introducing the concept of topology in two-dimensional magnetic systems. He also discussed the recent results from his team on magnetic vortices and skyrmions.

Prof. Qiu is from 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.

Prof. Qiu has won many important awards for his contributions 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.
