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 …

Via the N th Darboux transformation, a chain of nonsingular localized-wave solutions is
derived for a nonlocal nonlinear Schrödinger equation with the self-induced parity-time (PT) …

We introduce a new unified two-parameter {(ϵ x, ϵ t)| ϵ x, t=±1} wave model (simply called
Q ϵ x, ϵ t (n) model), connecting integrable local and nonlocal vector nonlinear Schrödinger …

We investigate the dynamical behavior of continuous and discrete Schrödinger systems
exhibiting parity-time (PT) invariant nonlinearities. We show that such equations behave in a …

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 …

The exploration of quantum‐inspired symmetries in optical and photonic systems has
witnessed immense research interest both fundamentally and technologically in a wide …

We investigate the existence and stability of in-phase three-pole and four-pole gap solitons
in the fractional Schrödinger equation supported by one-dimensional parity-time-symmetric …

We study the modulational instability and soliton solution for nonlocal Kundu–Eckhaus (KE)
equation which is distinctly different from KE equation. KE equation can describe the …

We introduce a class of physically intriguing PT-symmetric Dirac-δ-Scarf-II optical potentials.
We find the parameter region making the corresponding non-Hermitian Hamiltonian admit …
