Nonlinearity-induced localization in a periodically-driven semi-discrete system
R. Driben, V. V. Konotop, B. A. Malomed +2
We demonstrate that nonlinearity plays a constructive role in supporting the robustness of dynamical localization in a model which is discrete, in one dimension and continuous in t…
Dynamics of dipoles and vortices in nonlinearly-coupled three-dimensional harmonic oscillators
R. Driben, V. V. Konotop, B. A. Malomed +1
The dynamics of a pair of three-dimensional matter-wave harmonic oscillators (HOs) coupled by a repulsive cubic nonlinearity is investigated through direct simulations of the respe…
Multipoles and vortex multiplets in multidimensional media with inhomogeneous defocusing nonlinearity
Rodislav Driben, Nir Dror, Boris Malomed +1
We predict a variety of composite quiescent and spinning two- and three-dimensional (2D and 3D) self-trapped modes in media with a repulsive nonlinearity whose local strength grows…
Non-coaxial vortices in two-component Bose-Einstein condensates: Persistent precession and nutation
R. Driben, V. V. Konotop, T. Meier
It is demonstrated that a two-component Bose-Einstein condensate (BEC) with all-repulsive inter-atomic interactions loaded into a radially symmetric harmonic trap supports robust n…
Three-dimensional hybrid vortex solitons
Rodislav Driben, Yaroslav V. Kartashov, Boris A. Malomed +2
We show, by means of numerical and analytical methods, that media with a repulsive nonlinearity which grows from the center to the periphery support a remarkable variety of previou…
Soliton gyroscopes in media with spatially growing repulsive nonlinearity
Rodislav Driben, Yaroslav V. Kartashov, Boris A. Malomed +2
We find that the recently introduced model of self-trapping supported by a spatially growing strength of a repulsive nonlinearity gives rise to robust vortex-soliton tori, i.e., th…
