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…
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…
