Address: Lecture Hall, Area C, Tang Aoqing Building, Qianwei South District.
Summary of report:
From the first discovery in 2008, the Fe-basedsuperconductors (FeSCs) has been one main focus in the field of condensedmatter physics. In this talk, I will firstly introduce the basic physics of theFeSCs, where I will mainly focus on the electronic nematicity which has beenobserved ubiquitously in various experimental probes. I will then show theelectro nic nematic order parameters from symmetry analysis. One microscopicmechanism for the electronic nematicity in FeSCs will be finally discussed,which can unify the driving mechanism of the electronic nematicity, themagnetism and the superconductivity in FeSCs.
Brief introduction of the speaker:
From September 1991 to June 1995, Professor Su Yuehua studied in the Physics Department of Lanzhou University and obtained a Bachelor of Science degree. From September 1997 to August 2000, he studied for a master’s degree at the Institute of Theoretical Physics, Chinese Academy of Sciences and obtained a master’s degree in science. From September 2000 to August 2003, he studied for a doctoral degree at the Institute of Theoretical Physics, Chinese Academy of Sciences, and obtained a doctor of science degree. From October 2003 to August 2005, he worked as a postdoctoral fellow at the Advanced Research Center of Tsinghua University. From September 2005 to now, I worked in the School of Optoelectronic Information of Yantai University. The main research direction is low-dimensional strongly correlated electronic systems, such as copper-based/iron-based high-temperature superconductors and heavy Fermi subsystems; Ultracold atomic system; Strong correlation calculation method and so on.
