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,…
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…
Possible Spin-Singlet Superconductivity in (TMTSF)2X: Superconducting Transition Temperature in a Magnetic Field
Mitake Miyazaki, Keita Kishigi, Yasumasa Hasegawa
We study the transition temperature Tc(H) of a quasi-one-dimensional (Q1D) superconductivity which is derived from the quantum effect of an electron motion in a strong magnetic fie…
Superconductivity of Quasi-Two-Dimensional Tight-Binding Electrons in a Strong Magnetic Field
Mitake Miyazaki, Keita Kishigi, Yasumasa Hasegawa
We have investigated the transition temperature of superconductiv ity in quasi-two-dimensional (Q2D) tight-binding electrons in a strong magnetic field. When the mag…
Superconductivity of Quasi-One and Quasi-Two Dimensional Tight-Binding Electrons in Magnetic Field
Mitake Miyazaki, Keita Kishigi, Yasumasa Hasegawa
The upper critical field of the tight-binding electrons in the three-dimensional lattice is investigated. The electrons make Cooper pairs between the eigenstates with t…
