Abstract

The Kopnin mass and the Baym-Chandler mass of a vortex have the same origin. Both represent the mass of the normal component trapped by the vortex. The Kopnin mass of a vortex is formed by quasiparticles localized in the vicinity of the vortex. In the superclean limit it is calculated as a linear response, in exactly the same way as the density of the normal component is calculated in a homogeneous superfluid. The Baym-Chandler mass is the hydrodynamic (associated) mass trapped by a vortex. It is analogous to the normal component formed by inhomogeneities, such as pores and impurities. Both contributions are calculated for a generic model of a continuous vortex core.
