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…
Resonant mode interactions in nonlinear lattices
V. v. Konotop
Resonant mode interactions in weakly nonlinear multi-dimensional lattices and related effects are described. We concentrate on formal description of the phenomenon and consider as…
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…
On global existence of localized solutions of some nonlinear lattices
G. Perla Menzala, V. V. Konotop
We prove global existence and uniqueness of solutions of some important nonlinear lattices which include the Fermi-Pasta-Ulam (FPU) lattice. Our result shows (on a particular examp…
