Inertial Mass and Viscosity of Tilted Vortex Lines in Layered Superconductors

Abstract

The dynamics of tilted vortex lines in Josephson-coupled layered superconductors is considered within the time-dependent Ginzburg-Landau theory. The frequency and angular dependences of the complex-valued vortex mobility $\mu$ are studied. The components of the viscosity and inertial mass tensors are found to increase essentially for magnetic field orientations close to the layers. For superconducting/normal metal multilayers the frequency ($\omega$) range is shown to exist where the $\mu^{-1}$ value depends logarithmically on $\omega$.
