Unpredictable condensate–depletion dynamics in one-dimensional power-law traps

AR Sakhel, RR Sakhel - Journal of Physics: Condensed Matter, 2022 - iopscience.iop.org
The dynamic depletion of a trapped one-dimensional Bose–Einstein condensate (BEC) that
is driven by laser stirring is numerically explored using beyond mean-field methods. For this …

Oblique collisions and catching-up phenomena of vortex dipoles in a uniform Bose–Einstein condensate

G Yang, S Zhang, W Han - Physica Scripta, 2019 - iopscience.iop.org
We investigate the collisional dynamics of two vortex dipoles in a uniform two-dimensional
Bose–Einstein condensate. It is found that the dynamics are deeply related to the moving …

Propagation dynamics of off-axis symmetrical and asymmetrical vortices embedded in flat-topped beams

X Zhang, H Wang - Optics Communications, 2017 - Elsevier
In this paper, propagation dynamics of off-axis symmetrical and asymmetrical optical vortices
(OVs) embedded in flat-topped beams have been explored numerically based on rigorous …

Elements of Dynamics of a One-Dimensional Trapped Bose–Einstein Condensate Excited by a Time-Dependent Dimple: A Lagrangian Variational Approach

AR Sakhel, RR Sakhel - Journal of Low Temperature Physics, 2018 - Springer
We examine the dynamics of a one-dimensional harmonically trapped Bose–Einstein
condensate (BEC), induced by the addition of a dimple trap whose depth oscillates with …
