| Abstract: | Using the path integral representation,bulk thermodynamic properties of the two-dimensional Hubbard model on a square lattice are studied numerically using the hybrid Monte Carlo simulation algorithm.Results for averaged energy,spin-spin correlation functions and Cooper pair correlation functions are presented.All these results suggest that the system exhibits an anti-ferromagnetic correlation at half-filling for a wide range of temperature. |
