Combined unitary and symmetric group approach applied to low-dimensional spin systems
Werner Dobrautz, Vamshi M. Katukuri, Nikolay A. Bogdanov +3
A novel combined unitary and symmetric group approach is used to study the spin- Heisenberg model and related Fermionic systems in a spin-adapted representation, using…
Stochastic multi-reference perturbation theory with application to linearized coupled cluster method
Guillaume Jeanmairet, Sandeep Sharma, Ali Alavi
In this article we report a stochastic evaluation of the recently proposed LCC multireference perturbation theory [Sharma S., and Alavi A., J. Chem. Phys. 143, 102815, (2015)]. In…
Semistochastic Heat-bath Configuration Interaction method: selected configuration interaction with semistochastic perturbation theory
Sandeep Sharma, Adam Holmes, Guillaume Jeanmairet +2
We extend the recently proposed heat-bath configuration interaction (HCI) method [Holmes, Tubman, Umrigar, J. Chem. Theory Comput. 12, 3674 (2016)], by introducing a semistochastic…
Unbiased Reduced Density Matrices and Electronic Properties from Full Configuration Interaction Quantum Monte Carlo
Catherine Overy, George H. Booth, N. S. Blunt +3
Properties that are necessarily formulated within pure (symmetric) expectation values are difficult to calculate for projector quantum Monte Carlo approaches, but are critical in o…
