Uhr Thema : Theories of spin-nematic excitonic insulators in graphite under high magnetic field and quantum multi-criticality in disordered Weyl semimetal

In the first part of the talk, I will present our phenomenological theory for metal-insulator transitions in graphite under high magnetic field [1,2]. Graphite under high magnetic field exhibits consecutive metal-insulator (MI) transitions as well as re-entrant insulator-metal (IM) transition in the quasi-quantum limit at low temperature. We explain these… CONTINUE READING
