Abstract

We present results of quantum simulations for a system of strongly correlated fermions coupled to anharmonic phonons. The Projector Quantum Monte Carlo (PQMC) method has been employed to study ground state properties. In a parameter regime relevant for the high-T(c) superconductors, the system exhibits superconductivity, characterized by Off-Diagonal Long Range Order (ODLRO). Several features of the high-T(c) materials can be understood.
