Excitonic instabilities and spontaneous time-reversal symmetry breaking on the ...
Liu, Wei; Punnoose, Alexander [UNESP]Made available in DSpace on 2022-04-29T07:13:45Z (GMT). No. of bitstreams: 0 Previous issue date: 2014-01-16; We elucidate the close relationship between spontaneous time-reversal symmetry breaking and the physics of excitonic instabilities in strongly correlated multiband systems. The underlying mechanism responsible for the spontaneous breaking of time-reversal symmetry in a many-body system is closely relate...
Temperature-induced spontaneous time-reversal symmetry breaking on the honeycom...
Liu, Wei; Punnoose, Alexander [UNESP]Made available in DSpace on 2022-04-29T07:26:02Z (GMT). No. of bitstreams: 0 Previous issue date: 2015-04-30; Phase transitions involving spontaneous time-reversal symmetry breaking are studied on the honeycomb lattice at finite hole doping with next-nearest-neighbor repulsion. We derive an exact expression for the mean-field equation of state in closed form, valid at temperatures much less than the Fermi energ...
