(Color online) Contour-plot of the superfluid density \(\rho _s\) for the soft-core (\(n_{oc}=2\)) BH model on the cubic lattice at (a) \(T=0\), (b) \(T=0.05\), (c) \(T=0.1\) and (d) \(T=0.2\). The blue star in (a) locates the tip of the first Mott lobe. The data points vary from zero in the dark region (MI) to one in the light region (SF). Increasing T shrinks the SF regions.
