Research Abstract

We implemented an improved sampling method for QMC electronic structure calculations with leptokurtotic behaviour is its sampling distribution. The leptokurtotic property is the origin of the numerical instabilities in variational opitimizations and evaluations of local forces. Some appropriate extended ensamble sampling is proved to give better numerical stability and faster convergence in the variational optimization.
