ROUGH-SURFACE EFFECTS ON THE P-WAVE FERMI SUPERFLUIDS

Rough surface effects on p-wave Fermi superfluids are discussed on the basis of our recently proposed quasi-classical theory that can treat in a unified way the surface scattering ranging from the specular limi t to the diffusive limit. We show how the transition temperature of th e ABM state in a slab geometry depends on the surface roughness. In th e diffusive limit, our result agrees with Kjaldmann et al. We consider the BW state, the ABM state and the polar state in a half-infinite ge ometry with a plane rough surface and discuss the self-consistent orde r parameter and the surface density of states at low temperatures. The rough surface effects on the Andreev scattering in the BW state are a lso discussed within the same framework.
