We study the attractive (i.e., negative-U) Hubbard model on a triangular lattice. Quantum Monte-Carlo simulations indicate the absence of CDW for intermediate couplings, and show that the critical temperature for superconductivity is higher close to half filling, unlike the square lattice.
We investigate a magnetic transition in the half-filled Hubbard model on the triangular lattice. By making use of the path-integral renormalization group (PIRG) method with a spin-rotated frame, we calculate the ground state energy and charge/spin correlation functions for a cluster with 36 sites. W
