Abstract

We perform direct numerical simulations solving the equation of motion of vortices and the Maxwell equation combined with the London equation in order to investigate how the vortex motion excites the c-axis polarized plasma mode in highly anisotropic superconductors. We find that under both the presence of c-axis parallel transport currents and c-axis perpendicular applied magnetic field, the moving velocity of vortices has two components, which correspond to a constant flux flow velocity and an oscillating component caused by interactions with the superconducting plasma mode. Furthermore, we show that if no damping process exists, the power of the excited plasma can become very large within accessible conditions in real layered high-Tc superconductors, while the excited c-axis polarized electric field is proportional to the applied transport current and magnetic field, respectively.
