Charge-density wave induced by combined electron-electron and electron-phonon interactions in 1-TiSe: A variational Monte Carlo study
Hiroshi Watanabe, Kazuhiro Seki, Seiji Yunoki
To clarify the origin of a charge-density wave (CDW) phase in 1-TiSe, we study the ground state property of a half-filled two-band Hubbard model in a triangular lattice incl…

A variational Monte Carlo study of exciton condensation
Hiroshi Watanabe, Kazuhiro Seki, Seiji Yunoki
Exciton condensation in a two-band Hubbard model on a square lattice is studied with variational Monte Carlo method. We show that the phase transition from an excitonic insulator t…
