Out-of-Equilibrium Dynamics of the Bose-Hubbard Model
Figure 15
Experimentally determined phase diagram of bosons in a two-dimensional optical lattice [57] as a function of lattice depth (equivalently interaction strength) and characteristic density. Each circle on the phase diagram corresponds to an individual measurement. The blue region was predicted to support a Mott insulating phase in QMC calculations [192]. The red ovals mark the experimentally determined transition boundary to be compared with the blue line of theory. The size of the ovals represent the respective uncertainties in the phase boundary in density and chemical potential. The yellow dashed line is a fit to the experimentally determined phase boundary, and the green dashed line shows a set of data at fixed atom number . Adapted figure with permission of I. B.
