Abstract
The projector quantum Monte Carlo method is one of the most important numerical techniques in solid state physics to study the ground-state properties of many-electron systems. It can be applied to a variety of systems, but is most often used to study models for the recently discovered high-temperature superconducting compounds. We give a survey of the algorithm and discuss technical details and general problems that occur. Furthermore, we present a performance and error analysis for our implementation of the algorithm when applied to the 2-dimensional Hubbard model. It appears that massive parallelization can speed up and stabilize the final results, and more detailed studies will give rise to an improved parallel algorithm.
