Ferromagnetic diagonal stripe states in the two-dimensional Hubbard model with
Mitake Miyazaki, Takashi Yanagisawa
We have performed a variational Monte Carlo simulation to study the ground state of a two-dimensional Hubbard model on a square lattice in the strong coupling region. The energy ga…
Phase diagram of the three-band d-p model based on the optimization variational Monte Carlo method
Takashi Yanagisawa, Mitake Miyazaki, Kunihiko Yamaji
The phase diagram of cuprate high-temperature superconductors is investigated on the basis of the three-band d-p model. We use the optimization variational Monte Carlo method, wher…
Phase diagram and mechanism of superconductivity in a strongly correlated electron system
Takashi Yanagisawa, Mitake Miyazaki, Kunihiko Yamaji
We investigate the phase diagram of two-dimensional (2D) Hubbard model by employing the optimization variational Monte Carlo method. The 2D Hubbard model is the most simple electro…
Mott transition in cuprate high-temperature superconductors
Takashi Yanagisawa, Mitake Miyazaki
In this study, we investigate the metal-insulator transition of charge transfer type in high-temperature cuprates. We first show that we must introduce a new band parameter in the…
Correlated-Electron Systems and High Temperature Superconductivity
Takashi Yanagisawa, Mitake Miyazaki, Kunihiko Yamaji
We present recent theoretical results on superconductivity in correlated-electron systems, especially in the two-dimensional Hubbard model and the three-band d-p model. The mechani…
Superconducting Condensation Energy of the Two-Dimensional Hubbard Model in the Large-Negative-t' Region
Kunihiko Yamaji, Takashi Yanagisawa, Mitake Miyazaki +1
We compute the superconducting condensation energies Econd of Hg1201 and Tl2201 cuprates by applying the variational Monte Carlo method to the two-dimensional Hubbard model, first,…
