Nonlinear modes and symmetries in linearly-coupled pairs of PT-invariant dimers
K. Li, P. G. Kevrekidis, B. A. Malomed
The subject of the work are pairs of linearly coupled PT-symmetric dimers. Two different settings are introduced, namely, straight-coupled dimers, where each gain site is linearly…
Spatiotemporal vortex solitons in hexagonal arrays of waveguides
H. Leblond, B. A. Malomed, D. Mihalache
By means of a systematic numerical analysis, we demonstrate that hexagonal lattices of parallel linearly-coupled waveguides, with the intrinsic cubic self-focusing nonlinearity, gi…
Transition to miscibility in linearly coupled binary dipolar Bose-Einstein condensates
G. Gligoric, A. Maluckov, M. Stepic +2
We investigate effects of dipole-dipole (DD) interactions on immiscibility-miscibility transitions (IMTs) in two-component Bose-Einstein condensates (BECs) trapped in the harmonic-…
Discrete surface solitons in two dimensions
H. Susanto, P. G. Kevrekidis, B. A. Malomed +2
We investigate fundamental localized modes in 2D lattices with an edge (surface). Interaction with the edge expands the stability area for ordinary solitons, and induces a differen…
Polychromatic solitons in a quadratic medium
I. N. Towers, B. A. Malomed
We introduce the simplest model to describe parametric interactions in a quadratically nonlinear optical medium with the fundamental harmonic containing two components with (slight…
Nonlinear parametric instability in double-well lattices
Jaroslav Riedel, Eva Majernikova, Boris A. Malomed
A possibility of a nonlinear resonant instability of uniform oscillations in dynamical lattices with harmonic intersite coupling and onsite nonlinearity is predicted. Numerical sim…
Stability of narrow beams in bulk Kerr-type nonlinear media
B. Malomed, K. Marinov, D. Pushkarov +1
We consider (2+1)-dimensional beams, whose transverse size may be comparable to or smaller than the carrier wavelength, on the basis of an extended version of the nonlinear Schrödi…
Light Bullet Modes in Self-Induced-Transparency Media with Refractive Index Modulation
M. Blaauboer, G. Kurizki, B. A. Malomed
We predict the existence of a new type of spatiotemporal solitons ("light bullets") in two-dimensional self-induced-transparency media with refractive index modulation in the direc…
Nonsteady condensation and evaporation waves
Osamu Inomoto, Shoichi Kai, Boris Malomed
We study motion of a phase transition front at a constant temperature between stable and metastable states in fluids with the universal Van der Waals equation of state (which is va…
