In the mean-field approximation, the well-known effect of the critical quantum collapse in a 3D gas of particles pulled to the center by potential U(r)=−U0/2r2 is suppressed by repulsive inter-particle interactions, which create the otherwise non-e

We introduce one- and two-dimensional (1D and 2D) models of a degenerate bosonic gas composed of ions carrying positive and negative charges (cations and anions), under the condition of the electroneutrality. The system may exist in the mean-field co

This article provides a focused review of recent findings which demonstrate, in some cases quite counter-intuitively, the existence of bound states with a singularity of the density pattern at the center; the states are physically meaningful because

We consider possibilities to control dynamics of solitons of two types, maintained by the combination of cubic attraction and spin-orbit coupling (SOC) in a two-component system, namely, semi-dipoles (SDs) and mixed modes (MMs), by making the relativ

We consider a model of the exciton-polariton condensate based on a system of two Gross–Pitaevskii equations coupled by the second-order differential operator, which represents the spin–orbit coupling in the system. Also included are the linear ga

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 trapping potential, as the splitter for the incident soliton. An estim

We introduce a two-dimensional (2D) system which can be implemented in dual-core planar optical couplers with the Kerr nonlinearity in its cores, making it possible to blend the effects of ${ \mathcal P }{ \mathcal T }$ symmetry, represented by the b

This volume contains the proceedings of the third meeting in the series of symposia and workshops on nuclear medium effects. The topics covered include many-body forces in few-nucleon systems, nuclear interactions in the medium, medium effects in nuc

Vortex motion in coupled phase oscillator lattices is analogous to the dislocation motion in crystals. A single vortex exhibits a glide motion by force at the boundaries. Thermal fluctuations induce the glide motion even below the critical point corr
