Spontaneous symmetry breaking of solitons trapped in a double-channel potential
M. Matuszewski, B. A. Malomed, M. Trippenbach
We consider a two-dimensional (2D) nonlinear Schrodinger equation with self-focusing nonlinearity and a quasi-1D double-channel potential, i.e., a straightforward 2D extension of t…
New approximation for nonlinear evolution in periodic potentials
M. Matuszewski
A new approximation for evolution described by Nonlinear Schrodinger Equation (NLS) with periodic potential is presented. It relies on restricting dynamics to one band of the bandg…
Simple and efficient generation of gap solitons in Bose-Einstein condensates
Michal Matuszewski, Wieslaw Krolikowski, Marek Trippenbach +1
We suggest an efficient method for generating matter-wave gap solitons in a repulsive Bose-Einstein condensate, when the gap soliton is formed from a condensate cloud in a harmonic…
Crossover from self-defocusing to discrete trapping in nonlinear waveguide arrays
Michal Matuszewski, Christian R. Rosberg, Dragomir N. Neshev +6
We predict a sharp crossover from nonlinear self-defocusing to discrete self-trapping of a narrow Gaussian beam with the increase of the refractive index contrast in a periodic pho…
