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…
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…
Incommensurate Antiferromagnetism Coexisting with Superconductivity in Two-Dimensional d-p Model
Takashi Yanagisawa, Mitake Miyazaki, Kunihiko Yamaji
Numerical studies of the two-dimensional d-p model using the Gutzwiller ansatz have exhibited the incommensurate antiferromagnetic state coexisting with superconductivity in the un…
Fermi arc in doped high-Tc cuprates
Takashi Yanagisawa, Mitake Miyazaki, Kunihiko Yamaji
We propose a -density wave induced by the spin-orbit coupling in the CuO plane. The spectral function of high-temperature superconductors in the under doped and lightly doped re…

The ground state of the two-dimensional three-band Hubbard model in oxide superconductors is investigated by using the variational Monte Carlo method. The Gutzwiller-projected BCS…
Off-diagonal Wave Function Monte Carlo Studies of Hubbard Model I
Takashi Yanagisawa, Soh Koike, Kunihiko Yamaji
We propose a Monte Carlo method, which is a hybrid method of the quantum Monte Carlo method and variational Monte Carlo theory, to study the Hubbard model. The theory is based on t…

Takashi Yanagisawa, Soh Koike, Mitake Miyazaki +1
The non-uniform ground state of the two-dimensional three-band Hubbard model for the oxide high-Tc superconductors is investigated using a variational Monte Carlo method. We examin…
