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
Dark soliton stability bose-einstein condensate magnetic parabolic well optical lattice discrete nonlinear schrodinger equation
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 ...

Landau-Zener tunneling of Bose-Einstein condensates in an optical lattice
Condensate asymmetric tunnel deep optical lattice linear coupled nonlinear schrodinger equation
2014/12/29
A theory of the nonsymmetric Landau-Zener tunneling of Bose-Einstein condensates in deep optical lattices is presented. It is shown that periodic exchange of matter between the bands is described by a...
Stability of quantized vortices in a Bose-Einstein condensate confined in an optical lattice
Linear stability quantization whirlpool nonlinear schrodinger equation
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...
