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…
Sliding-Window Normalization to Improve the Performance of Machine-Learning Models for Real-Time Motion Prediction Using Electromyography
Taichi Tanaka, Isao Nambu, Yoshiko Maruyama +1
Many researchers have used machine learning models to control artificial hands, walking aids, assistance suits, etc., using the biological signal of electromyography (EMG). The use…
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,…
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…
Variational Monte Carlo Study of a Spinless Fermion t-V Model on a Triangular Lattice: Formation of a Pinball Liquid
M. Miyazaki, C. Hotta, S. Miyahara +2
We analyze a model of spinless fermions on a triangular lattice at half-filling interacting via strong nearest-neighbor repulsive interactions, V, using the variational Monte Carlo…
t'- and t"-dependence of the bulk-limit superconducting condensation energy of the 2D Hubbard model
K. Yamaji, T. Yanagisawa, M. Miyazaki +1
The 2D Hubbard model having the 2nd- and 3rd-neighbor transfer energies t' and t" is investigated by use of the variational Monte Carlo method. At the nearly optimal doping with on…
