Quantum Monte Carlo study of disordered fermions
Physical Review B
We study a strongly correlated fermionic model with attractive interactions in the presence of disorder in two spatial dimensions. Our model has been designed so that it can be solved using the recently discovered meron-cluster approach. Although the model is unconventional it has the same symmetries of the Hubbard model. Since the naive algorithm is inefficient, we develop a new algorithm by combining the meron-cluster technique with the directed-loop update. This combination allows us todoi:10.1103/physrevb.72.024525 fatcat:55yllnxzbncaznwa4qpomlfqou
