On the modulational stability of Gross-Pittaevskii type equations in 1+1 dimensions
Z. Rapti, P. G. Kevrekidis, V. V. Konotop
The modulational stability of the nonlinear Schr{ö}dinger (NLS) equation is examined in the cases with linear and quadratic external potential. This study is motivated by recent ex…
Soliton generation of two-component Bose-Einstein condensates in optical lattices
N. A. Kostov, V. Z. Enol'skii, V. S. Gerdjikov +2
Coupled nonlinear Schrodinger equations (CNLS) with an external elliptic function potential model a quasi one--dimensional interacting two-component Bose-Einstein condensate trappe…
On creation and evolution of dark solitons in Bose-Einstein condensates
V. A. Brazhnyi, A. M. Kamchatnov, V. V. Konotop
Generation of dark solitons from large initial excitations and their evolution in a quasi-one-dimensional Bose-Einstein condensate trapped by a harmonic potential is studied analyt…
Dynamics of a Bose-Einstein condensate in optical trap
F. Kh. Abdullaev, B. B. Baizakov, V. V. Konotop
The dynamics of a 2D Bose-Einstein condensate in optical trap is studied taking into consideration fluctuations of the far-off-resonance laser field intensity. The problem is descr…
