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…
Systematics of the strength of superconductivity of the d-p model in relation to cuprates
Kunihiko Yamaji, Takashi Yanagisawa
Cuprate high-Tc superconductors are known to have several relationships between Tc and features of electronic structure. In the firstly found one, Tc is correlated with the Madelun…
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…
Vortices and chirality in multi-band superconductors
Takashi Yanagisawa, Yasumoto Tanaka, Izumi Hase +1
We investigate several important properties of multi-band superconductors. They are time-reversal symmetry breaking, chirality and fractional quantum flux vortices in three-band su…
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,…
