Topological superconductors are among the most actively studied materials these days. They are a promising candidate for hosting Majorana fermions either on their boundaries or in vortex cores. Detecting one-dimensional (1D) edge current around the periphery of a 2D ${p}_{x}+i{p}_{y}$ superconductor would be a hallmark signature of topological superconductivity, but …
