A quantum Monte Carlo study of systems with effective core potentials and node nonlinearities
Haihan Zhou, Anthony Scemama, Guangming Wang +4
We study beryllium dihydride (BeH) and acetylene (CH) molecules using real-space diffusion Monte Carlo (DMC) method. The molecules serve as perhaps the simplest prototy…

Weighted nodal domain averages of eigenstates for quantum Monte Carlo and beyond
Lubos Mitas, Abdulgani Annaberdiyev
We study the nodal properties of many-body eigenstates of stationary Schrödinger equation that affect the accuracy of real-space quantum Monte Carlo calculations. In particular, we…
