Electronic Polarizability of Superconductors and Inertial Mass of a Moving Vortex

The problem of a vortex electromagnetic mass in a superconductor is considered accounting for the self-interaction effect conditioned by the coupling of the moving vortex to the excited fluctuations of the superfluid density. In the framework of the phenomenological model used, the self-interaction is defined as an interaction of the singular phase with the induced polarization of the charged superfluid. The obtained polaron-type mass exceeds the earlier obtained electromagnetic mass in view of the large value of the light speed relation to the Fermi velocity c/vF, and can dominate over the vortex core mass.
