Rationale and Scope:
Since its discovery in 2008, the high-temperature Fe-based superconductors have been the subject of intense worldwide research. As the field progresses during the second decade, exciting new understandings and questions continue to emerge at a rapid pace on a variety of topics. The RCQM symposium will bring together active experimentalists and theorists to highlight the recent achievements on several particularly vibrant topics, and engage in discussions about the future directions of this field.
The symposium will revolve around the following focus topics on Fe-based superconductivity:
- Electron Correlations and Orbital Selectivity
- Quantum Criticality
- Nematicity
- Electronic Topology
The total number of invited speakers will be close to 15.
Invited Speakers:
Electron Correlations/Orbital Selectivity:
Roser Valenti (Goethe U., Frankfurt, Germany)
Gabriel Kotliar (Rutgers U.)
Rong Yu (Renmin U., China)
Jianwei Huang (Rice U.)
Quantum Criticality:
Matthias Ikeda (Stanford U.)
Nigel Hussey (Radboud U., Netherlands)
Amalia Coldea (Oxford U., U.K.)
Ding Hu (Hangzhou Normal, China)
Nematicity:
Donglai Feng (USTC, Hefei, China)
Taka Shibauchi (U. Tokyo, Japan)
Anna Böhmer (KIT, Karlsruhe, Germany)
Paul Malinowski (U. Washington)
Yu Song (Zhejiang University)
Electronic Topology:
Peng Zhang (U. Tokyo, Japan)
Vidya Madhavan (UIUC)
Ryan Day (UBC, Canada)
Ziqiang Wang (Boston College)
Format:
The symposium will be held online. There will be six sessions of invited talks (each lasting 20 minutes, plus 10 minutes of discussion). To accommodate participants from all continents, we plan to have morning and night sessions during each day of the three day period.
The morning sessions will be between 10am-11:30am US CST that should work for everyone except in Asia, and the night sessions between 8:30-10pm US CST for everyone except those from Europe.
We hope to have the permission to record the talks, so that we can make the video recordings available after each session, and the participants from Asia and Europe can have immediate access to the talks given in a previous session that they were unable to attend.
