Phase diagram of the two-dimensional extended Hubbard model: Phase transitions between different pairing symmetries when charge and spin fluctuations coexist
Seiichiro Onari, Ryotaro Arita, Kazuhiko Kuroki +1
In order to explore how superconductivity arises when charge fluctuations and spin fluctuations coexist, we have obtained a phase diagram against the off-site repulsion V and band…

Possibility of superconductivity in the repulsive Hubbard model on the Shastry-Sutherland lattice
Takashi Kimura, Kazuhiko Kuroki, Ryotaro Arita +1
Possibility of superconductivity from electron repulsion in the Shastry-Sutherland lattice, which has a spin gap at half filling, is explored with the repulsive Hubbard model in th…
