Nonlocal gap solitons in PT-symmetric periodic potentials with defocusing nonlinearity
Chandroth P. Jisha, Alessandro Alberucci, Valeriy A. Brazhnyi +1
Existence and stability of PT-symmetric gap solitons in a periodic structure with defocusing nonlocal nonlinearity are studied both theoretically and numerically. We find that, for…
Localized modes in two-dimensional Schroedinger lattices with a pair of nonlinear sites
Valeriy A. Brazhnyi, Boris A. Malomed
We address the existence and stability of localized modes in the two-dimensional (2D) linear Schroedinger lattice with two symmetric nonlinear sites embedded into it, and a general…
Scattering of gap solitons by PT-symmetric defects
F. Kh. Abdullaev, V. A. Brazhnyi, M. Salerno
The resonant scattering of gap solitons (GS) of the periodic nonlinear Schrödinger equation with a localized defect which is symmetric under the parity and the time-reversal (PT) s…
Dynamical generation of interwoven soliton trains by nonlinear emission in binary Bose-Einstein condensates
V. A. Brazhnyi, David Novoa, Chandroth P. Jisha
We propose a method for the generation of trains of alternating bright solitons in two-component Bose-Einstein condensates, using controlled emission of nonlinear matter-waves in t…
Interaction of discrete nonlinear Schrödinger solitons with a linear lattice impurity
Valeriy A. Brazhnyi, Chandroth P. Jisha, A. S. Rodrigues
The interaction of moving discrete solitons with a linear Gaussian defect is investigated. Solitons with profiles varying from hyperbolic secant to exponentially localized are cons…
Dragging two-dimensional discrete solitons by moving linear defects
V. A. Brazhnyi, B. A. Malomed
We study the mobility of small-amplitude solitons attached to moving defects which drag the solitons across a two-dimensional (2D) discrete nonlinear-Schrödinger (DNLS) lattice. Fi…
