Significats de quantum monte carlo en anglès

Using the constrained-path quantum Monte Carlo method, we systematically study the half-filled Hubbard model on AA-stacked honeycomb lattice.

To obtain results at zero temperature, we employ the projective quantum Monte Carlo method as an impurity solver.

In this communication, we propose a method for obtaining isolated excited states within the full configuration interaction quantum Monte Carlo framework.

We illustrate our findings with a simple model and realistic quantum Monte Carlo simulations for bosonic atoms and compare the latter to experiments.
