Thsi figure shows computed spatial densities (a,b,c) and the corresponding phase
profiles (d,e,f)of the gas at the respective temperatures, T = (0.2, 0.7 and 0.9)T0, below
the ideal-gas BEC temperature, T0. The low temperature phase coherent BEC (a,d), and
the phase
fluctuating BKT (c,f) phases are separated by a vortex-pair creation transition.
As temperature is further increased the super
fluidity is destroyed at the BKT-normal transition.
