Accelerating Stochastic Quantum Chemistry
Verena A. Neufeld, Alex J. W. Thom
The convergence of full configuration interaction quantum Monte Carlo (FCIQMC) is accelerated using a quasi-Newton propagation (QN) which can also be applied to coupled cluster Mon…
The HANDE-QMC project: open-source stochastic quantum chemistry from the ground state up
James S. Spencer, Nick S. Blunt, Seonghoon Choi +15
Building on the success of Quantum Monte Carlo techniques such as diffusion Monte Carlo, alternative stochastic approaches to solve electronic structure problems have emerged over…
Exciting determinants in Quantum Monte Carlo: Loading the dice with fast, low memory weights
Verena A. Neufeld, Alex J. W. Thom
High-quality excitation generators are crucial to the effectiveness of Coupled cluster Monte Carlo (CCMC) and full configuration interaction Quantum Monte Carlo (FCIQMC) calculatio…
Large Scale Parallelization in Stochastic Coupled Cluster
James S. Spencer, Verena A. Neufeld, William A. Vigor +2
Coupled cluster theory is a vital cornerstone of electronic structure theory and is being applied to ever-larger systems. Stochastic approaches to quantum chemistry have grown in i…
