Contribution

It introduces a velocity-dependent analysis of current distributions in moving vortices using time-dependent London equations, including thin film effects.

Findings

Normal and persistent current distributions depend on vortex velocity.

Distributions near Pearl vortex cores in thin films show unique features.

The study provides detailed velocity-dependent current profiles.

Abstract

We take account of normal currents that emerge when vortices move. Moving Abrikosov vortices in the bulk and Pearl vortices in thin films are considered. Velocity dependent distributions of both normal and persistent currents are studied in the frame of time-dependent London equations. In thin films near the Pearl vortex core, these distributions are intriguing in particular.
