Formation of rogue waves and modulational instability with zero-wavenumber gain in multicomponent systems with coherent coupling

L Liu, WR Sun, BA Malomed - Physical Review Letters, 2023 - APS
It is known that rogue waves (RWs) are generated by the modulational instability (MI) of the
baseband type. Starting with the Bers-Kaup-Reiman system for three-wave resonant …

Discrete flat-band solitons in the kagome lattice

RA Vicencio, M Johansson - Physical Review A—Atomic, Molecular, and …, 2013 - APS
We consider a model for a two-dimensional kagome lattice with defocusing nonlinearity, and
show that families of localized discrete solitons may bifurcate from localized linear modes of …

Creating two-dimensional bright solitons in dipolar Bose-Einstein condensates

P Köberle, D Zajec, G Wunner, BA Malomed - Physical Review A—Atomic …, 2012 - APS
We propose a realistic experimental setup for creating quasi-two-dimensional (2D) bright
solitons in dipolar Bose-Einstein condensates (BECs), the existence of which was proposed …

Time-localized dark modes generated by zero-wave-number-gain modulational instability

L Liu, WR Sun, BA Malomed, PG Kevrekidis - Physical Review A, 2023 - APS
We report the emergence of a previously unexplored species of solitary waves, viz., time-
localized dark modes in integrable and nonintegrable variants of the massive Thirring model …

Mobility of solitons in one-dimensional lattices with the cubic-quintic nonlinearity

C Mejía-Cortés, RA Vicencio, BA Malomed - Physical Review E—Statistical …, 2013 - APS
We investigate mobility regimes for localized modes in the discrete nonlinear Schrödinger
(DNLS) equation with the cubic-quintic on-site terms. Using the variational approximation …

Controlled mobility of compact discrete solitons in nonlinear Lieb photonic lattices

B Real, RA Vicencio - Physical Review A, 2018 - APS
We study the mobility of localized solutions in a nonlinear Lieb photonic lattice. We
characterize different families of nonlinear solutions looking for different regions of …

Lattice solitons with quadrupolar intersite interactions

Y Li, J Liu, W Pang, BA Malomed - Physical Review A, 2013 - APS
We study two-dimensional (2D) solitons in the mean-field models of ultracold gases with
long-range quadrupole-quadrupole interaction (QQI) between particles. The condensate is …

Experimental study of the interplay between dynamic localization and Anderson localization

D Guzman-Silva, M Heinrich, T Biesenthal… - Optics Letters, 2020 - opg.optica.org
We investigate the interplay between two fundamentally different localization mechanisms in
discrete systems: dynamic localization, ie, resonant wave packet revivals in periodically …

Bright solitons in quasi-one-dimensional dipolar condensates with spatially modulated interactions

FK Abdullaev, A Gammal, BA Malomed, L Tomio - Physical Review A—Atomic …, 2013 - APS
We introduce a model for the condensate of dipolar atoms or molecules, in which the dipole-
dipole interaction (DDI) is periodically modulated in space due to a periodic change of the …
