Zero-variance principle for Monte Carlo algorithms
Roland Assaraf, Michel Caffarel
We present a general approach to greatly increase at little cost the efficiency of Monte Carlo algorithms. To each observable to be computed we associate a renormalized observable…

Metal-insulator transition in the one-dimensional SU(N) Hubbard model
Roland Assaraf, Patrick Azaria, Michel Caffarel +1
We investigate the metal-insulator transition of the one-dimensional SU(N) Hubbard model for repulsive interaction. Using the bosonization approach a Mott transition in the charge…
