Abstract
Numerical simulations were carried out using a projector quantum Monte Carlo method. Ground state energies are presented for the single band Hubbard model for system sizes 4 × 4 to 8 × 8. The Hubbard model coupled to a two-level system (e.g. bridging oxygen) was also studied. Enhancement of superconducting susceptibilities indicates the possibility of high-Tc superconductivity.
