New variational Monte Carlo method with an energy variance extrapolation
for large-scale shell-model calculations    [PDF]

Takahiro Mizusaki, Noritaka Shimizu

We propose a new variational Monte Carlo (VMC) method with an energy variance
extrapolation for large-scale shell-model calculations. This variational Monte
Carlo is a stochastic optimization method with a projected correlated condensed
pair state as a trial wave function, and is formulated with the M-scheme
representation of projection operators, the Pfaffian and the Markov-chain Monte
Carlo (MCMC). Using this method, we can stochastically calculate approximated
yrast energies and electro-magnetic transition strengths. Furthermore, by
combining this VMC method with energy variance extrapolation, we can estimate
exact shell-model energies.
