Anisotropy on the Fermi Surface of the Two-Dimensional Hubbard Model
Y. Otsuka, Y. Morita, Y. Hatsugai
We investigate anisotropic charge fluctuations in the two-dimensional Hubbard model at half filling. By the quantum Monte Carlo method, we calculate a momentum-resolved charge comp…

Mott Transition in the Two-Dimensional Flux Phase
Y. Otsuka, Y. Hatsugai
Effects of the electron-electron interaction in the two-dimensional flux phase are investigated. We treat the half-filled Hubbard model with a magnetic flux per plaquette by th…
