Figure 3

Comparison between the condensate fraction \(n_0/n\) (upper panel) and the superfluid fraction \(n_s/n\) (lower panel) in the thermodynamic limit and at finite size (f.s.), as functions of \(\sqrt{a_s^3 n}\), for \(T^* = 0.0,\,0.7\). The IR cutoff is fixed at \(q_\text {IR} = \sqrt{4\pi \gamma } = \sqrt{4\pi a_s n^{1/3}}\).
