Emergence and Stability of Vortex Clusters in Bose-Einstein Condensates: a Bifurcation Approach near the Linear Limit
S. Middelkamp, P. G. Kevrekidis, D. J. Frantzeskakis +2
We study the existence and stability properties of clusters of alternating charge vortices in Bose-Einstein condensates. It is illustrated that such states emerge from cascades of…
Dark solitons in mode-locked lasers
Mark J. Ablowitz, Theodoros P. Horikis, Sean D. Nixon +1
Dark soliton formation in mode-locked lasers is investigated by means of a power-energy saturation model which incorporates gain and filtering saturated with energy, and loss satur…
Perturbations of Dark Solitons
Mark J. Ablowitz, Sean D. Nixon, Theodoros P. Horikis +1
A method for approximating dark soliton solutions of the nonlinear Schrodinger equation under the influence of perturbations is presented. The problem is broken into an inner regio…
Collisional-inhomogeneity-induced generation of matter-wave dark solitons
C. Wang, P. G. Kevrekidis, T. P. Horikis +1
We propose an experimentally relevant protocol for the controlled generation of matter-wave dark solitons in atomic Bose-Einstein condensates (BECs). In particular, using direct nu…
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…
Effects of Long-Range Nonlinear Interactions in Double-Well Potentials
C. Wang, P. G. Kevrekidis, D. J. Frantzeskakis +1
We consider the interplay of linear double-well-potential (DWP) structures and nonlinear longrange interactions of different types, motivated by applications to nonlinear optics an…
