Item 33(33, 33) Cisternas, Jaime; Cartes, Carlos; Descalzi, Orazio; Albers, Tony; Radons, Günter; 33The propagation of light pulses in dual-core nonlinear optical fibers is studied using a model proposed by Sakaguchi and Malomed. The system consists of a supercritical complex Ginzburg-Landau equation coupled to a linear equation. Our analysis includes single standing and walking solitons as well as walking trains of 3, 5, 6, and 12 solitons. For the characterization of the different scenarios, we used ensemble-averaged square displacement of the soliton trajectories and time-averaged power spectrum of the background waves. Power law spectra, indicative of turbulence, were found to be associated with random walks. The number of solitons (or their separations) can trigger anomalous random walks or totally suppress the background waves.Item Breaking of symmetry of interacting dissipative solitons can lead to partial annihilationDescalzi, Orazio; Brand, Helmut R.Item Characterization of time-dependence for dissipative solitons stabilized by nonlinear gradient terms: Periodic and quasiperiodic vs chaotic behaviorDescalzi, Orazio; Facão, M.; Cartes, Carlos; Carvalho, M.
