Abstract
The two-dimensional half-filled extended Hubbard model is studied by means of Quantum Monte Carlo simulation. The model includes the on-site electron interaction (U) and nearest-neighbor interaction (V). We study the formation of antiferromagnetic, charge-density-wave, and superconducting states of the model as the parameters of the model are varied.Keywords
