Chiral $p-$wave superconductivity in Pb${}_{1-x}$Sn${}_x$Te: signatures from bound-state spectra and wavefunctions

S. Kundu, V. Tripathi

Surface superconductivity has recently been observed on the (001) surface of the topological crystalline insulator Pb${}_{1-x}$Sn${}_x$Te using point-contact spectroscopy, and theore…
