We elaborate a model of the interferometer which, unlike previously studied ones, uses a
local (δ-functional) nonlinear repulsive potential, embedded into a harmonic-oscillator …

We consider a matter-wave bright soliton interferometer composed of a harmonic potential
trap with a Rosen-Morse barrier at its center on which an incident soliton collides and splits …

The interaction of matter–wave solitons with a potential barrier is a fundamentally important
problem, and the splitting and subsequent recombination of the soliton by the barrier is the …

In this communication, we have constructed a generalized nonlinear Schrödinger equation
based on nonlocal quantum momentum square operator. Single and bright singular combo …

We consider evolution of one-dimensional nonlinear-Schrödinger (NLS) two-soliton
complexes (breathers) with narrow repulsive or attractive potentials (barrier or well …

We investigate numerically the collisions of two distinguishable quantum matter-wave bright
solitons in a one-dimensional harmonic trap. We show that such collisions can be used to …

We investigate the ground state (GS) of a collisionless Bose-Einstein condensate (BEC)
trapped in a soft one-dimensional optical lattice (OL), which is formed by two …

We explore the impact of dimensionality on the scattering of a small bosonic ensemble in an
elongated harmonic trap off a centered repulsive barrier, thereby taking particle correlations …

Scattering quantum bright solitons off barriers has been predicted to lead to nonlocal
quantum superpositions, in particular the NOON state. The focus of this paper lies on …

We consider the interaction of two-component bright-bright solitons with a narrow potential
barrier (splitter) in the framework of a system of two Gross-Pitaevskii (nonlinear-Schrödinger) …
