An \(N\)-channel spinless p-wave superconducting wire is known to go through a series of \(N\) topological phase transitions upon increasing the disorder strength. Here, we show that at each of those transitions the density of states shows a Dyson singularity \(\nu(\varepsilon) \propto \varepsilon^{...
