Abstract
We study a subgap quasiparticle spectrum in a mesoscopic disk of
chiral superconductor. We find an exact expression for the spectrum of
surface states localized at the disk edge. Considering an Abrikosov vortex
placed at the center of a superconducting disk we investigate the spectrum
transformation near the intersection points of surface and vortex anomalous
energy branches . The resulting splitting of the anomalous branches due to
the hybridization of edge and vortex states is determined by an external
magnetic field and can lead in particular to the formation of a set of
minigaps in the quasiparticle spectrum. Tuning the external magnetic field
makes it possible to control the width of minigaps and the positions of
corresponding density of states singularities at the minigaps edges.
