A Phenomenological Theory of Loop-Current Phases
Shimpei Goto, Susumu Kurihara
A phenomenological theory of the loop-current and loop-spin-current phases is proposed. In order to investigate the stability of these phases, a Ginzburg-Landau-Wilson type action…

Spontaneous loop-spin current with topological characters in the Hubbard model
Shimpei Goto, Keisuke Masuda, Susumu Kurihara
We find a state characterized by a spontaneous loop-spin current and a single-particle gap in the Hubbard model within the variational cluster approach. This state exists for arbit…
