Two-component gap solitons with linear interconversion
Sadhan K. Adhikari, Boris A. Malomed
We consider one-dimensional solitons in a binary Bose-Einstein condensate with linear coupling between the components, trapped in an optical-lattice potential. The inter-species an…
Stabilization of two-dimensional solitons and vortices against supercritical collapse by lattice potentials
Rodislav Driben, Boris A. Malomed
It is known that optical-lattice (OL) potentials can stabilize solitons and solitary vortices against the critical collapse, generated by the cubic attractive nonlinearity in the 2…
Wave patterns generated by a supersonic moving body in a binary Bose-Einstein condensate
Yu. G. Gladush, A. M. Kamchatnov, Z. Shi +3
Generation of wave structures by a two-dimensional object (laser beam) moving in a two-dimensional two-component Bose-Einstein condensate with a velocity greater than both sound ve…
Gap solitons on a ring
Yaroslav V. Kartashov, Boris A. Malomed, Victor A. Vysloukh +1
We introduce a new species of gap solitons (GSs) supported by an azimuthally modulated guiding ring in defocusing cubic media. The periodicity in the azimuthal direction strongly m…
Localized matter-waves patterns with attractive interaction in rotating potentials
Hidetsgu Sakaguchi, Boris Malomed
We consider a two-dimensional (2D) model of a rotating attractive Bose-Einstein condensate (BEC), trapped in an external potential. First, an harmonic potential with the critical s…
Spontaneous symmetry breaking in a nonlinear double-well structure
Thawatchai Mayteevarunyoo, Boris A. Malomed, Guangjiong Dong
We propose a model of a nonlinear double-well potential (NDWP), alias a double-well pseudopotential, with the objective to study an alternative implementation of the spontaneous sy…
