Simulation of a modified Hubbard model with a chemical potential using a meron-cluster algorithm

Abstract

We show how a variant of the Hubbard model can be simulated using a meron-cluster algorithm. This provides a major improvement in our ability to determine the behavior of these types of models. We also present some results that clearly demonstrate the existence of a superconducting state in this model.
