Loop Current and Antiferromagnetic States in Fermionic Hubbard Model with Staggered Flux at Half Filling
Yuta Toga, Hisatoshi Yokoyama
Anticipating realization of interacting fermions in an optical lattice with a large gauge field, we consider phase transitions and loop currents in a two-dimensional S=1/2 fermioni…

Drude and Superconducting Weights and Mott Transitions in Variation Theory
Shun Tamura, Hisatoshi Yokoyama
Drude weight () is a useful measure to distinguish a metal from an insulator. However, has not been justifiably estimated by the variation theory for long, since Millis and…
