Wave Functions of Correlated-Electron State in the Periodic Anderson Model

Abstract

We investigate the periodic Anderson model by a variational Monte Carlo method. A new wave function is proposed based on the well-known Gutzwiller wave function. We calculated the physical properties by using the Monte Carlo algorithm to consider the strong correlation effects. The ground state energy is improved considerably by taking into account electron-hole excitation effects.
