Abstract
We present numerical simulations of long Josephson junctions in the presence of an rf bias and an applied magnetic field, which we model with a sine-Gordon-like equation. We focus our attention on quasiperiodic and chaotic dynamics and their transitions. We show that quasiperiodicity arises from the competition between two incommensurate frequencies: one due to the success of the system in exciting a solitonlike structure and the second one due to the rf drive. We demonstrate the universality of the multifractal structure of the attractor at the onset of chaos.
