Domain walls in chiral p-wave superconductors: Quasiparticle spectrum and dynamics

Abstract

We calculate microscopically the viscous friction coefficient and the effective mass of domain walls separating regions of opposite chirality in p-wave superconductors with k_x\pm ik_y order parameter. The domain wall viscosity and inertia are determined by the transitions between different Bogoliubov quasiparticle states induced by the domain wall motion. As a by-product, we present a detailed analysis of the quasiparticle spectrum, both bound and scattering, in the presence of a general domain wall with an arbitrary phase difference between the domains.
