Self-healing diffusion quantum Monte Carlo algorithms: methods for direct reduction of the fermion sign error in electronic structure calculations
Fernando A. Reboredo, Randolph Q. Hood, Paul R. C. Kent
We develop a formalism and present an algorithm for optimization of the trial wave-function used in fixed-node diffusion quantum Monte Carlo (DMC) methods. We take advantage of a b…

Neutral and charged excitations in carbon fullerenes from first-principles many-body theories
Murilo L. Tiago, P. R. C. Kent, Randolph Q. Hood +1
We investigate the accuracy of first-principles many-body theories at the nanoscale by comparing the low energy excitations of the carbon fullerenes C_20, C_24, C_50, C_60, C_70, a…
