説明
We propose a Monte Carlo method, which is a hybrid method of the quantumMonte Carlo method and variational Monte Carlo theory, to study the Hubbard model.The theory is based on the off-diagonal and the Gutzwiller type correlation factors which are taken into account by a Monte Carlo algorithm.In the 4×4 system our method is able to reproduce the exact results obtained by the diagonalization. An application is given to investigate the half-filled band case of two-dimensional square lattice.The energy is favorably compared withquantum Monte Carlo data.
