Line Plot from Scientific Research

Superfluid phase stiffness \({K}_{{\mathrm{g}}}=\sqrt{{E}_{{\mathrm{J}}}/(2{E}_{{\mathrm{g}}})}\) , experimentally inferred from plasma modes in f , versus B (black line; black markers show every fifth data point). Theoretically expected superconducting and insulating regimes are labelled, and demarcated by a band covering the clean 2 and dirty 27 limits.
