Zero-Variance Zero-Bias Principle for Observables in quantum Monte Carlo: Application to Forces

Roland Assaraf, Michel Caffarel

A simple and stable method for computing accurate expectation values of observable with Variational Monte Carlo (VMC) or Diffusion Monte Carlo (DMC) algorithms is presented. The ba…

Dynamical Symmetry Enlargement Versus Spin-Charge Decoupling in the One-Dimensional SU(4) Hubbard Model

R. Assaraf, P. Azaria, E. Boulat +2

We investigate dynamical symmetry enlargement in the half-filled SU(4) Hubbard chain using non-perturbative renormalization group and Quantum Monte Carlo techniques. A spectral gap…
