The dynamical playground of a higher-order cubic Ginzburg-Landau equation: from orbital connections and limit cycles to invariant tori and the onset of chaos
V. Achilleos, A. R. Bishop, S. Diamantidis +4
The dynamical behavior of a higher-order cubic Ginzburg-Landau equation is found to include a wide range of scenarios due to the interplay of higher-order physically relevant terms…
Collapse for the higher-order nonlinear Schrödinger equation
V. Achilleos, S. Diamantidis, D. J. Frantzeskakis +3
We examine conditions for finite-time collapse of the solutions of the higher-order nonlinear Schrödinger (NLS) equation incorporating third-order dispersion, self-steepening, line…
Nonlinear PT-symmetric models bearing exact solutions
H. Xu, P. G. Kevrekidis, Q. Zhou +3
We study the nonlinear Schrdinger equation with a PT-symmetric potential. Using a hydrodynamic formulation and connecting the phase gradient to the field amplitude, allow…
Matter-wave solitons in the counterflow of two immiscible superfluids
F. Tsitoura, V. Achilleos, B. A. Malomed +3
We study formation of solitons induced by counterflows of immiscible superfluids. Our setting is based on a quasi-one-dimensional binary Bose-Einstein condensate (BEC), composed of…
Beating dark-dark solitons in Bose-Einstein condensates
D. Yan, J. J. Chang, C. Hamner +6
Motivated by recent experimental results, we study beating dark-dark solitons as a prototypical coherent structure that emerges in two-component Bose-Einstein condensates. We showc…
Dynamics of Dark-Bright Solitons in Cigar-Shaped Bose-Einstein Condensates
S. Middelkamp, J. J. Chang, C. Hamner +6
We explore the stability and dynamics of dark-bright solitons in two-component elongated Bose-Einstein condensates by developing effective 1D vector equations as well as solving th…
