Non-autonomous bright-dark solitons and Rabi oscillations in multi-component Bose-Einstein condensates
T. Kanna, R. Babu Mareeswaran, F. Tsitoura +2
We study the dynamics of non-autonomous bright-dark matter-wave solitons in two- and three- component Bose-Einstein condensates. Our setting includes a time-dependent parabolic pot…
Rogue Waves In Nonlinear Schrödinger Models with Variable Coefficients: Application to Bose-Einstein Condensates
J. S. He, E. G. Charalampidis, P. G. Kevrekidis +1
We explore the form of rogue wave solutions in a select set of case examples of nonlinear Schrödinger equations with variable coefficients. We focus on systems with constant disper…
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…
Conservation laws, exact travelling waves and modulation instability for an extended nonlinear Schrödinger equation
V. Achilleos, S. Diamantidis, D. J. Frantzeskakis +2
We study various properties of solutions of an extended nonlinear Schrödinger (ENLS) equation, which arises in the context of geometric evolution problems -- including vortex filam…
Exploring Vortex Dynamics in the Presence of Dissipation: Analytical and Numerical Results
D. Yan, R. Carretero-González, D. J. Frantzeskakis +3
In this paper, we systematically examine the stability and dynamics of vortices under the effect of a phenomenological dissipation used as a simplified model for the inclusion of t…
From Nodeless Clouds and Vortices to Gray Rings and Symmetry-Broken States in Two-Dimensional Polariton Condensates
A. S. Rodrigues, P. G. Kevrekidis, R. Carretero-González +3
We consider the existence, stability and dynamics of the nodeless state and fundamental nonlinear excitations, such as vortices, for a quasi-two-dimensional polariton condensate in…
