Vortices in a Bose-Einstein condensate confined by an optical lattice
Vortex dynamics condensate optical lattice parabolic magnetic trap dynamics
2014/12/29
We investigate the dynamics of vortices in repulsive Bose–Einstein condensates in the presence of an optical lattice (OL) and a parabolic magnetic trap. The dynamics is sensitive to the phase of the O...
Stability of dark solitons in a Bose-Einstein condensate trapped in an optical lattice

2014/12/29
We investigate the stability of dark solitons (DSs) in an effectively one-dimensional Bose-Einstein condensate in the presence of the magnetic parabolic trap and an optical lattice (OL). The analysis ...

2014/12/25
Using a time-dependent linear (Rabi) coupling between the components of a weakly interacting multicomponent Bose-Einstein condensate (BEC), we propose a protocol for transferring the wave function of ...

2014/12/25
We investigate the existence and especially the linear stability of single- and multiple-charge quantized vortex states of nonlinear Schrödinger equations in the presence of a periodic and a para...
Dynamics of vortex formation in merging Bose-Einstein condensate fragments
Condensation of vortex bose-einstein condensate independent optical potential
2014/12/24
We study the formation of vortices in a Bose-Einstein condensate (BEC) that has been prepared by allowing isolated and independent condensed fragments to merge together. We focus on the experimental s...
Spinor Bose-Einstein condensate flow past an obstacle
Spinor bose-einstein condensate macroscopic nonlinear structure vortex ring
2014/12/24
We study the flow of a spinor (F=1) Bose-Einstein condensate in the presence of an obstacle. We consider the cases of ferromagnetic and polar spin-dependent interactions, and find that the system demo...

2014/12/24
Generation of wave structures by a two-dimensional (2D) object (laser beam) moving in a 2D two-component Bose-Einstein condensate with a velocity greater than the two sound velocities of the mixture i...
