Excited states using semistochastic heat-bath configuration interaction
Adam A. Holmes, C. J. Umrigar, Sandeep Sharma
We extend our recently-developed heat-bath configuration interaction (HCI) algorithm, and our semistochastic algorithm for performing multireference perturbation theory, to the cal…
Efficient heat-bath sampling in Fock space
Adam Holmes, Hitesh J. Changlani, C. J. Umrigar
We introduce an algorithm for sampling many-body quantum states in Fock space. The algorithm efficiently samples states with probability approximately proportional to an arbitrary…
Semistochastic Projector Monte Carlo Method
F. R. Petruzielo, A. A. Holmes, Hitesh J. Changlani +2
We introduce a semistochastic implementation of the power method to compute, for very large matrices, the dominant eigenvalue and expectation values involving the corresponding eig…
