SIMULATIONS OF INTERACTING MANY-BODY SYSTEMS USING P4

Monte Carlo (MC) and Molecular Dynamics (MD) simulations are powerful tools for understanding the low temperature properties of systems of i nteracting electrons and phonons in a solid, including the phenomena o f magnetism and superconductivity. When mobile electrons are studied, these simulations are currently limited to a few hundred particles, an d also largely to ''clean'' systems where no defects are present. Ther efore, more powerful machines and algorithms must be used to address m any of the most important issues in the field. In this paper, we prese nt results from using some simple implementations of the p4 parallel p rogramming system on a variety of parallel architectures to conduct MC and MD simulations of one and two dimensional electron-phonon models.
