High Accuracy Transition Metal Effective Cores for the Many-Body Diffusion Monte Carlo Method
Bennett, M. C., Reboredo, F. A., Mitas, L., & Krogel, J. T. (2022, January 10). JOURNAL OF CHEMICAL THEORY AND COMPUTATION.

Efficient quantum monte carlo energies for molecular dynamics simulations
PHYSICAL REVIEW LETTERS, 94(5).
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.
