Variational Monte Carlo studies of a t-J model on an anisotropic triangular lattice
Tsutomu Watanabe, Hisatoshi Yokoyama, Yukio Tanaka +2
With the insulating phase of κ-(BEDT-TTF)_2X in mind, we study a t-J model on an anisotropic triangular lattice, where the hopping integral is t' in one of the three directions, us…

Variational Monte Carlo Studies of Pairing Symmetry for the t-J Model on a Triangular Lattice
Tsutomu Watanabe, Hisatoshi Yokoyama, Yukio Tanaka +2
As a model of a novel superconductor Na_xCoO_2\cdotyH_2O, a single-band t-J model on a triangular lattice is studied, using a variational Monte Carlo method. We calculate the energ…
