Quantum Monte Carlo study of the first-row atoms and ions

P. Seth, P. López Ríos, R. J. Needs

Quantum Monte Carlo calculations of the first-row atoms Li-Ne and their singly-positively-charged ions are reported. Multi-determinant-Jastrow-backflow trial wave functions are use…

Energies of the first row atoms from quantum Monte Carlo

Matthew Brown, John Robert Trail, Pablo Lopez Rios +1

All-electron variational and diffusion quantum Monte Carlo calculations of the ground state energies of the first row atoms (Li to Ne) are reported. We use trial wavefunctions of f…

Strategies for improving the efficiency of quantum Monte Carlo calculations

R. M. Lee, G. J. Conduit, N. Nemec +2

We describe a number of strategies for minimizing and calculating accurately the statistical uncertainty in quantum Monte Carlo calculations. We investigate the impact of the sampl…

Continuum variational and diffusion quantum Monte Carlo calculations

R. J. Needs, M. D. Towler, N. D. Drummond +1

This topical review describes the methodology of continuum variational and diffusion quantum Monte Carlo calculations. These stochastic methods are based on many-body wave function…
