R. Kleiner et al., Stacked long Josephson junctions in zero magnetic field: A numerical studyof coupled one-dimensional sine-Gordon equations, PHYS REV B, 62(6), 2000, pp. 4086-4095
We present a systematic numerical study of the coupled one-dimensional sine
-Gordon equations for a stack of 20 Josephson junctions, with junction para
meters that are representative for intrinsic Josephson junctions in Bi2SrCa
2Cu2O8. Simulations were performed for zero external magnetic field. We fou
nd a large variety of fluxon and antifluxon modes, often involving the exci
tation of collective Josephson plasma oscillations;or cavity resonances. Re
presentative states are discussed in detail.
