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 review of (chiefly, theoretical) results for self-trapped states (solitons) in
two-and three-dimensional (2D and 3D) models of nonlinear dissipative media. The …

This work investigates the existence and stability of soliton families in cubic–quintic–septic
Gross–Pitaevskii equation under non-PT-symmetric complex potentials. The cubic and …

We present an alternative type of parity-time (PT)-symmetric generalized Scarf-II potentials,
which makes possible for non-Hermitian Hamiltonians in the classical linear Schrödinger …

We present a procedure for nonlinearity management of metal-dielectric nanocomposites
(MDNCs). Varying the volume fraction occupied by silver nanoparticles (NPs) suspended in …

We demonstrate two new types of non-circularly-symmetric solitons, the elliptical and
rectangular solitons, which can be sustained by the cubic–quintic nonlinearity in the …

We discover that the physically interesting P T-symmetric Dirac delta-function potentials can
not only make sure that the non-Hermitian Hamiltonians admit fully-real linear spectra but …

We study a class of physically intriguing PT-symmetric generalized Scarf-II (GS-II) potentials,
which can support exact solitons in one-and multi-dimensional nonlinear Schrödinger …

Higher-dimensional PT-symmetric potentials constituted by delta-sign-exponential (DSE)
functions are created in order to show that the exceptional points in the non-Hermitian …
