dx2−y2-Density Wave and dx2−y2-wave Superconducting Gap on the Extended Hubbard Model on a Square Lattice: Approach to Finite Temperature Properties

We investigate the finite temperature properties of the extended Hubbard model with a nearest-neighbor Coulomb repulsion on the square lattice. Solving the self-consistent equations obtained using our mean-field theory [J. Phys. Soc. Jpn. 88, 084706 (2019)] numerically, we obtain three-dimensional p...
