“…Referring to real systems, we observe that the effect of spatial inhomogeneities is central to the properties of long Josephson junctions. One of the present authors (A.T.F) has worked intensively on the formation of stable bound states of fluxons in inhomogeneous long Josephson junctions Filipov 1982, 1984;Filipov and Gal'pern 1983;Filipov et al 1987). The predicted bound fluxons have been observed experimentally (Vystavkin et al 1988).…”

Stochasticity in the Josephson map

The Josephson map describes the nonlinear dynamics of systems characterized by the standard map with a uniform external bias superposed. The intricate structures of the phase-space portrait of the Josephson map are examined here on the basis of the associated tangent map. A numerical investigation of stochastic diffusion in the Josephson map is compared with the renormalized diffusion coefficient calculated using the characteristic function. The global stochasticity of the Josephson map occurs at far smaller values of the stochastic parameter than is the case of the standard map.
