Collective Josephson vortex dynamics interacting with transverse Josephson plasma modes in intrinsic Josephson junctions

Abstract

We perform large-scale numerical simulations for Josephson vortex dynamics interacting with transverse plasma modes in intrinsic Josephson junctions by employing the coupled Sine-Gordon (CSG) equation. The simulation results reveal that I–V characterisitics show three clear step-like structures, where structural transitions of Josephson vortex lattice flow states occur due to resonances with transverse propagating Josephson plasma modes. We show that in-phase rectangular vortex lattice flow states leading to strong electromagnetic wave radiations can appear in a wide region of the I–V characterisitics in intrinsic Josephson junctions.
