The energy levels of fermions bound to the vortex core are considered for the general case of chiral superconductors. There are two classes of chiral superconductivity: in the class I superconducting state the axisymmetric singly quantized vortex has the same energy spectrum of bound states as in an s-wave superconductor: E=(n+1/2)ω0, with integral n. In class II the corresponding spectrum is E=nω0 and thus contains a state with exactly zero energy. The effect of a single impurity on the… Expand
Condensation of fermion zero modes in the vortex
The energy levels of the fermions bound to the vortex are considered for vortices in the superfluid/superconducting systems that contain the symmetry protected plane of zeroes in the gap function inExpand
Effects of Weak and Strong Scatterers on the Spectra of Vortex Andreev Bound States in Two-Dimensional Chiral p-wave Superconductors

Vortex-mediated microwave absorption in superclean layered superconductors
In the superclean case the spectrum of vortex core excitations in the presence of disorder is not random but consists of two series of equally spaced levels [Phys. Rev. B, 57, 5457 (1997)]. TheExpand

Mutual friction is calculated within a microscopic quantum-mechanical Green's-function formalism, valid for dynamical processes, and it is predicted that strong dissipation should be observed at a resonant frequency of about 10 kHz, owing to transitions between the bound-state energy levels. Expand
