基于我们最近提出的准经典理论，讨论了 p 波费米超流体的粗糙表面效应，该理论可以统一处理从镜面极限到扩散极限的表面散射。我们展示了板坯几何形状中 ABM 状态的转变温度如何取决于表面粗糙度。在扩散极限下，我们的结果与 Kjäldmann 等人一致。我们考虑具有平面粗糙表面的半无限几何中的BW态、ABM态和极性态，并讨论低温下自洽序参数和态的表面密度。在同一框架内还讨论了 BW 状态下粗糙表面对 Andreev 散射的影响。
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 limit to the diffusive limit. We show how the transition temperature of the ABM state in a slab geometry depends on the surface roughness. In the diffusive limit, our result agrees with Kjäldmann et al. We consider the BW state, the ABM state and the polar state in a half-infinite geometry with a plane rough surface and discuss the self-consistent order parameter and the surface density of states at low temperatures. The rough surface effects on the Andreev scattering in the BW state are also discussed within the same framework.
