The Gross-Pitaevskii-Poisson model for an ultracold plasma: density waves and solitons
Hidetsugu Sakaguchi, Boris A. Malomed
We introduce 1D and 2D models of a degenerate bosonic gas composed of ions with positive and negative charges (cations and anions). The system may exist in the mean-field condensat…
Robust PT symmetry of two-dimensional fundamental and vortex solitons supported by spatially modulated nonlinearity
Eitam Luz, Vitaly Lutsky, Er'el Granot +1
The real spectrum of bound states produced by PT-symmetric Hamiltonians usually suffers breakup at a critical value of the strength of gain-loss terms, i.e., imaginary part of the…
Symmetry breaking in laser cavities
Boris A. Malomed
A brief introduction to the topic of spontaneous symmetry breaking (SSB) in conservative and dissipative nonlinear systems with an underlying double-well-potential structure is giv…
Trapping of two-component matter-wave solitons by mismatched optical lattices
Z. Shi, K. J. H. Law P. G. Kevrekidis, B. A. Malomed
We consider a one-dimensional model of a two-component Bose-Einstein condensate in the presence of periodic external potentials of opposite signs, acting on the two species. The in…
Bose-Einstein condensates under a spatially-modulated transverse confinement
L. Salasnich, A. Cetoli, B. A. Malomed +2
We derive an effective nonpolynomial Schrodinger equation (NPSE) for self-repulsive or attractive BEC in the nearly-1D cigar-shaped trap, with the transverse confining frequency pe…
Optical Solitons in Periodic Media with Resonant and Off-Resonant Nonlinearities
G. Kurizki, A. E. Kozhekin, T. Opatrny +1
The properties of optical solitons in periodic nonlinear media are reviewed. The emphasis is on solitons in periodically refractive media (Bragg gratings) incorporating a periodic…
