Out-of-Equilibrium Dynamics of the Bose-Hubbard Model

Average spatial correlations as a function of site separation after a quench from to in (a) 1 dimension and (b) 2 dimensions. Squares indicate the results from exact diagonalization and triangles indicate results from t-DMRG. The diamonds show the result of equilibrium QMC calculations, and the circles indicate the zero temperature correlations in the ground state for and [97]. Adapted figure with permission from C.
