The U = ∞ Hubbard model with few holes: Monte Carlo studies near half-filling at non-zero temperatures

Abstract

We present an efficient Monte Carlo method to study the properties of the infinitely repulsive Hubbard model with few holes at finite non-zero temperatures. Using this method, magnetic and specific heat results are presented for a 10 × 10 lattice with two holes. Our results show that the magnetization increases with decreasing temperature for such a finite system.
