Recent progress on nonlinear properties of parity-time (PT)-symmetric systems is
comprehensively reviewed in this article. PT symmetry started out in non-Hermitian quantum …

One of the challenges of the modern photonics is to develop all‐optical devices enabling
increased speed and energy efficiency for transmitting and processing information on an …

This article offers a comprehensive survey of results obtained for solitons and complex
nonlinear wave patterns supported by nonlinear lattices (NLs), which represent a spatially …

The existence of localized modes supported by the PT-symmetric nonlinear lattices is
reported. The system considered reveals unusual properties: unlike other typical dissipative …

The observation of PT symmetry in a coupled optical waveguide system that involves a
complex refractive index has been demonstrated impressively in the experiment by Rüter et …

The interaction of fractional diffraction and parity-time (PT) symmetric would bring some
unique properties to certain physical system. Here we report a spontaneous symmetry …

This work presents an analytical study of the existence of solitons in non-Kerr law media
modulated by the P T-symmetric mixed linear and nonlinear optical complex lattices. Four …

The nonlinear dynamics induced by the modulation instability (MI) of a binary mixture in an
atomic Bose-Einstein condensate (BEC) is investigated theoretically under the joint effects of …

We study the families of nonlinear modes described by the nonlinear Schrödinger equation
with the PT-symmetric harmonic potential x 2− 2 i α x. The nonlinear modes found display a …

Dynamics of a chain of interacting parity-time-invariant nonlinear dimers is investigated. A
dimer is built as a pair of coupled elements with equal gain and loss. A relation between …
