报告人简介：

    Dr. Ying Liu is a professor of physics at Pennsylvania State University. He received a B. S. degree from Peking University, Beijing, a M. S. degree at Institute of Physics, Chinese Academy of Sciences, Beijing, and a Ph. D. degree from University of Minnesota, all in physics. He joined the faculty of Department of Physics, Pennsylvania State University in 1994 after spending three years as a postdoctoral research associate at University of Colorado in Boulder. He has visiting positions at Shanghai Jiaotong University and Zhejiang University. His current research centers in contemporary experimental condensed matter and materials physics, focusing on superconductivity and physics of quantum electronic materials. Systems under current study include chiral p-wave superconductor Sr2RuO4, mesoscopic and single-sheet superconductors, graphene and topological insulators, surfaces and interfaces of transition metal oxides, and strongly correlated quantum materials. Dr. Liu received an NSF Career Award in 1997 and is a fellow of American Physical Society. He received a NSFC Jieqing grant (Type B) in 2006 and was a Chang Jiang Jiangzuo Professor at Zhejiang University from 2007 to 2010.

报告摘要：April 8, 2011 was the precise date for superconductivity to have been discovered for one hundred years. Many other great discoveries have been made related to this remarkably quantum phenomenon since then. In particular, six or seven Nobel prizes were rewarded to works on or related to superconductivity. I will first present a brief introduction of the phenomenon and physics of superconductivity, and then an overview of the current research conducted in my own laboratory, focusing on the work on unconventional chiral p-wave and mesoscopic superconductivity. I will discuss in particular our phase-sensitive measurements indicating that Sr2RuO4 is a chiral p-wave superconductor and our discovery of the destructive regime predicted by de Gennes, the 1994 physics Nobel laureate. Finally, I will comment on outstanding issues and future trends in this exciting direction of condensed matter physics.
