ICTP Seminar Series in Condensed Matter and Statistical Physics: Multi-orbital Mott Physics and the Iron-based Superconductors
Starts 15 Mar 2018 11:00
Ends 15 Mar 2018 12:00
Central European Time
Leonardo Building - Luigi Stasi Seminar Room
We review some surprising results on multi orbital Hubbard models, highlighting the role of the Hund’s coupling in driving a two-stage Mott localization and an effective decoupling between the orbitals which in turn leads to a remarkable differentiation between different orbitals (orbital selectivity).
We show that the normal state of iron-based superconductors can be rationalized and understood in this framework and we address the implications on the phase diagram.
