Variational cluster approach to s-wave pairing in heavy-fermion superconductors
Keisuke Masuda, Daisuke Yamamoto
We study s-wave Cooper pairing in heavy-fermion systems. We analyze the periodic Anderson model by means of the variational cluster approach (VCA) focusing on the interorbital Coop…

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…
