Langevin dynamics for linear scaling quantum Monte Carlo
ORAL
Abstract
We discuss recent advances in quantum Monte Carlo (QMC) sampling for models of interacting electrons. A shortcoming of traditional determinant QMC is its cubic scaling with system size. The alternative Langevin approach offers, in principle, linear scaling. With some new tricks, the Langevin method can be very competitive with determinant QMC. Applications to the Holstein model of electron-phonon interactions will be presented.
