Overview

QMcBeaver is a quantum Monte Carlo code that was developed for electronic structure calculations using VMC and DMC methods. While the code represents earlier QMC development efforts and may not be as actively maintained as modern alternatives, it remains available for historical reference and educational purposes. QMcBeaver implemented standard QMC algorithms for molecular and solid-state systems.
