Abstract

We consider the dynamics of a Josephson vortex lattice in layered superconductors with magnetic, charge (electrostatic), and charge-imbalance (quasiparticle) interactions between interlayer Josephson junctions taken into account. The macroscopic dynamical equations for the interlayer Josephson phase differences, intralayer charge, and electron-hole imbalance are obtained and used for numerical simulations. Different transformations of the vortex lattice structure are observed. It is shown that additional dissipation due to charge-imbalance relaxation leads to stability of the triangular lattice.
