Optimizing large parameter sets in variational quantum Monte Carlo

Eric Neuscamman, C. J. Umrigar, Garnet Kin-Lic Chan

We present a technique for optimizing hundreds of thousands of variational parameters in variational quantum Monte Carlo. By introducing iterative Krylov subspace solvers and by mu…
