Revisiting the surface density of states of midgap Andreev edge states
Gota Sato, Yasushi Nagato, Seiji Higashitani
We revisit the effect of surface roughness on midgap Andreev edge states (MAES) in p- and d- wave superconductors. For a perfectly specular surface, MAES form a flat band at the Fe…

Lifetime of edge modes at rough surfaces of chiral superconductors
Seiji Higashitani, Gota Sato, Yasushi Nagato
We study the effect of diffuse surface scattering on the edge modes in two-dimensional chiral superconductors with time-reversal symmetry-breaking Cooper pairs, each carrying angul…
