  The charging effect of a superconducting vortex core is very important for
transport properties of superconducting vortices. The chiral p-wave
superconductor, known as a topological superconductor (SC), has a Majorana
fermion in a vortex core and the charging effect has been studied using
microscopic Bogoliubov-de Gennes (BdG) theory. According to calculations based
on the BdG theory, one type of the vortex is charged as well as the vortex of
the s-wave SC, while the other is uncharged. We reproduce this interesting
charging effect using an augmented quasiclassical theory in chiral p-wave SCs,
by which we can deal with particle-hole asymmetry in the quasiclassical
approximation.
