Stacked long Josephson junctions in zero magnetic field: A numerical study of coupled one-dimensional sine-Gordon equations
Abstract
We present a systematic numerical study of the coupled one-dimensional sine-Gordon equations for a stack of 20 Josephson junctions, with junction parameters that are representative for intrinsic Josephson junctions in Bi2SrCa2Cu2O8. Simulations were performed for zero external magnetic field. We found a large variety of fluxon and antifluxon modes, often involving the excitation of collective Josephson plasma oscillations or cavity resonances. Representative states are discussed in detail.
