Symmetry breaking in competing single-well linear-nonlinear potentials
Dmitry A. Zezyulin, Mikhail E. Lebedev, Georgy L. Alfimov +1
The combination of linear and nonlinear potentials, both shaped as a single well, enables competition between the confinement and expulsion induced by the former and latter potenti…

Localized modes in the Gross-Pitaevskii equation with a parabolic trapping potential and a nonlinear lattice pseudopotential
G. L. Alfimov, L. A. Gegel, M. E. Lebedev +2
We study localized modes (LMs) of the one-dimensional Gross-Pitaevskii/nonlinear Schrödinger equation with a harmonic-oscillator (parabolic) confining potential, and a periodically…
