Scaling of the gap, fidelity susceptibility, and Bloch oscillations across the superfluid to Mott insulator transition in the one-dimensional Bose-Hubbard model
Juan Carrasquilla, Salvatore R. Manmana, Marcos Rigol
We investigate the interaction-induced superfluid-to-Mott insulator transition in the one-dimensional Bose-Hubbard model (BHM) for fillings , , and by studying the…

Superfluid to normal phase transition in strongly correlated bosons in two and three dimensions
Juan Carrasquilla, Marcos Rigol
Using quantum Monte Carlo simulations, we investigate the finite-temperature phase diagram of hard-core bosons (XY model) in two- and three-dimensional lattices. To determine the p…
