Stability of excited states of a Bose-Einstein condensate in an anharmonic trap
Dmitry A. Zezyulin, Georgy L. Alfimov, Vladimir V. Konotop +1
We analyze the stability of non-ground nonlinear states of a Bose-Einstein condensate in the mean field limit in effectively 1D (``cigar-shape'') traps for various types of confini…
Nonlinear modes for the Gross-Pitaevskii equation -- demonstrative computation approach
G. L. Alfimov, D. A. Zezyulin
A method for the study of steady-state nonlinear modes for Gross-Pitaevskii equation (GPE) is described. It is based on exact statement about coding of the steady-state solutions o…
Mixed symmetry localized modes and breathers in binary mixtures of Bose-Einstein condensates in optical lattices
H. A. Cruz, V. A. Brazhnyi, V. V. Konotop +2
We study localized modes in binary mixtures of Bose-Einstein condensates embedded in one-dimensional optical lattices. We report a diversity of asymmetric modes and investigate the…
Stationary localized modes in the quintic nonlinear Schrodinger equation with a periodic potential
G. L. Alfimov, V. V. Konotop, P. Pacciani
We consider the localized modes (bright solitons) described by one-dimensional quintic nonlinear Schrodinger equation with a periodic potential. In the case of attractive nonlinear…
On classification of intrinsic localized modes for the Discrete Nonlinear Schrödinger Equation
G. L. Alfimov, V. A. Brazhnyi, V. V. Konotop
We consider localized modes (discrete breathers) of the discrete nonlinear Schrödinger equation , , . We…
