Fig. 3: Mini-gap distributions.
From: Zero energy states clustering in an elemental nanowire coupled to a superconductor
Normalized histograms of the mini-gap Δg for B = 0 T (a) and B = 5 T (b). The bar height is the value of the probability density function (PDF) at the bin, normalized such that the integral over the range is 1. Curves are PDF of Wigner surmise (WS) in orange and Tracy-Widom (TW) in blue, with solid lines for Gaussian orthogonal ensemble (GOE) and dashed lines for Gaussian unitary ensemble (GUE). The dark gray bar at Δg in b indicates the weight of Δg values that could not be evaluated.
