Metastable soliton necklaces confined by the boundary of a flattop region
Dmitry A. Zezyulin
We present quasistationary ring-shaped soliton necklaces in a two-component envelope propagating in a medium with competing cubic-quintic nonlinearity. Metastable propagation of so…
Quantized transport of solitons in Bose-Einstein condensates driven by spin-orbit coupling
Yaroslav V. Kartashov, Vladimir V. Konotop, Dmitry A. Zezyulin
We demonstrate that linear and nonlinear Thouless pumping can be realized in two-component elongated Bose-Einstein condensates using helicoidal spin-orbit coupling that slides with…
Towards the complete description of stationary states of a Bose-Einstein condensate in a one-dimensional quasiperiodic lattice: A coding approach
G. L. Alfimov, A. P. Fedotov, Ya. A. Murenkov +1
We consider stationary states of an effectively one-dimensional Bose-Einstein condensate in a quasiperiodic lattice. We formulate sufficient conditions for a one-to-one corresponde…
Double-flat-top half-vortices and self-bound solitary wave billiards in cubic-quintic media with intermodal attraction
Dmitry A. Zezyulin
We consider a bimodal light field envelope propagating in a bulk medium characterized by competing cubic and quintic nonlinearities. The subfields are coupled by a cross-phase modu…
Transverse instability of hybrid solitons in the strong light-matter coupling regime
Alexey V. Yulin, Dmitry A. Zezyulin
We investigate the transverse instability of two-component solitons forming in a planar waveguide operating in the regime of strong light-matter coupling. The instability emerges a…
Localized Floquet modes in arrays of out-of-phase curved waveguides with a quasiperiodic modulation
Yaroslav V. Kartashov, Dmitry A. Zezyulin
We study light propagation in an array of periodically curved waveguides consisting of pairs of waveguides with out-of-phase oscillations of waveguide centers. We compute the corre…
