Title: Novel superconductors from quantum paramagnets

Room 245 of the Physics Research Building

TUESDAY, February 21, 2017

Snacks at 2:45 pm. Colloquium at 3:00 pm.

 Abstract: Superconductivity has been around for more than 100 years. A major challenge still remains as to how to understand strongly correlated superconductors with predictive power. Here we propose a new paradigm for superconductivity building on quantum paramagnets.  Such a paradigm enables us to propose a new design pattern, namely a metal/quantum-paramagnet heterostructure, which hosts superconductivity with nontrivial topological properties. Furthermore we use such a paradigm to provide a unified framework that explains the various puzzling phenomena of a new iron-based superconductor FeSe: its exotic spin dynamics, nematicity without magnetic ordering, and unconventional superconductivity.
