A comparison between quantum chemistry and quantum Monte Carlo techniques for the adsorption of water on the (001) LiH surface
Theodoros Tsatsoulis, Felix Hummel, Denis Usvyat +7
We present a comprehensive benchmark study of the adsorption energy of a single water molecule on the (001) LiH surface using periodic coupled cluster and quantum Monte Carlo theor…

Boosting the accuracy and speed of quantum Monte Carlo: size-consistency and time-step
Andrea Zen, Sandro Sorella, Michael J. Gillan +2
Diffusion Monte Carlo (DMC) simulations for fermions are becoming the standard to provide high quality reference data in systems that are too large to be investigated via quantum c…
