Variational study of conduction in doped Mott insulator in terms of kinetic energy
H. Yokoyama, S. Tamura, K. Kobayashi +1
The kinetic features of holes (electrons) in the Hubbard model are studied using a variational Monte Carlo method. In doped Mott insulators (U>U_co), holes are classified, in the s…

Variational Monte Carlo Study of Spin-Gapped Normal State and BCS-BEC Crossover in Two-Dimensional Attractive Hubbard Model
Shun Tamura, Hisatoshi Yokoyama
We study properties of normal, superconducting (SC) and CDW states for an attractive Hubbard model on the square lattice, using a variational Monte Carlo method. In trial wave func…
