Seminar: Iron-based high temperature superconductivity after a decade — progresses and prospects

Qimiao Si

Rice University


Time: 15:30-16:30, Monday, August 27, 2018

Location: Room 242, East 4, Zijingang Campus



The iron-based high temperature superconductors have been the subject of enormous efforts during the past decade. In this talk, I will summarize some of the key questions on their physics and the progresses that have been made in addressing them. These questions concern both the normal state, including the degree of electron correlations as well as the electronic orders and their fluctuations, and the superconductivity. I will close by touching upon some of the outstanding questions and the prospects for future advances.


About the speaker

Prof. Qimiao Si is the Harry C. and Olga K. Wiess Professor of physics and Astronomy at Rice University. He came to the United States through the highly selective CUSPEA program in 1986, upon earning his B.S. in Physics from University of Science and Technology of China. He received his Ph.D. in Physics in 1991 from the University of Chicago and subsequently did postdoctoral work at Rutgers University and University of Illinois at Urbana-Champaign. He has been on the faculty of Rice University since 1994.

Prof. Si works in the field of theoretical condensed matter physics. His major contributions have been in the area of strongly correlated electron systems, including quantum criticality and emergent quantum phases, magnetic heavy fermion metals, high temperature superconductors, and mesoscopic and disordered electronic systems.

As of December 2015, he has published over 170 scientific articles (including 19 in Science, Nature, Nature Group Journals and PNAS, and 41 in Physical Review Letters) and has given more than 290 invited talks (including over 150 at conferences) on his research. He has served as a General Member of the Aspen Center for Physics (since 2009) and on the Advisory Editorial Board of Journal of Physics – Condensed Matter (2002-2006), and has co-chaired a number of international conferences and workshops, including the 2007 International Conference on Strongly Correlated Electron Systems (SCES’07) and the 2014 KITP Program on Magnetism, Bad Metals and Superconductivity — Iron Pnictides and Beyond.
