Diffusion Monte Carlo using domains in configuration space
Roland Assaraf, Emmanuel Giner, Vijay Gopal Chilkuri +3
The sampling of the configuration space in diffusion Monte Carlo (DMC) is done using walkers moving randomly. In a previous work on the Hubbard model [\href{https://doi.org/10.1103…
The Fermion Monte Carlo revisited
Roland Assaraf, Michel Caffarel, Anatole Khelif
In this work we present a detailed study of the Fermion Monte Carlo algorithm (FMC), a recently proposed stochastic method for calculating fermionic ground-state energies [M.H. Kal…
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…
