Efficient quantum monte carlo energies for molecular dynamics simulations

PHYSICAL REVIEW LETTERS, 94(5).

By: J. Grossman* & L. Mitas*

TL;DR: A method is presented to treat electrons within the many-body quantum Monte Carlo (QMC) approach "on-the-fly" throughout a molecular dynamics simulation, which results in highly accurate total energies for the full dynamical trajectory at a fraction of the cost of conventional, discrete sampling.
