This book offers a comprehensive review of the state-of-the-art theoretical and experimental advances in linear and nonlinear parity-time-symmetric systems in various physical disciplines, and surveys the emerging applications of parity-time (PT) symmetry. PT symmetry originates from quantum mechanics...
Parity-time symmetrynonlinear optical couplernon-Hermitian Hamiltonian with real spectraThis work analyses the propagation of soliton beam in parityCtime () symmetric nonlinear coupled systems with varying loss/gain profiles. When the loss/gain coefficient is a constant, the phase transition takes place...
parity‐time symmetryAs an elementary processor of neural networks, a neuron performs exotic dynamic functions, such as bifurcation, repetitive firing, and oscillation quenching. To achieve ultrafast neuromorphic signal processing, the realization of photonic equivalents to neuronal dynamic functions has ...
As a corollary to their hallmark protected edge transport, the conventional understanding of such systems holds that they are intrinsically closed, that is, that they are assumed to be entirely isolated from the surrounding world. Here, by demonstrating a parity–time-symmetric topological insulator,...

parity-time ( \mathcal{PT} \mathcal{PT} ) symmetric systems, have attracted tremendous attention over the past decade. Their exotic properties arise from exceptional point (EP) degeneracies of non-Hermitian Hamiltonians that govern their dynamics. In recent years, increasingly sophisticated models ...
Synthetic non-conservative systems with parity-time (PT) symmetric gain-loss structures can exhibit unusual spontaneous symmetry breaking that accompanies spectral singularity. Recent studies on PT symmetry in optics and weakly interacting open quantum systems have revealed intriguing physical properties, yet...

In non-Hermitian PT-symmetric systems, we can define adirectionality, stemming from the broken parity-symmetry. For instance, a PT-symmetric structure with loss in the bottom and gain in the top can be defined asup, whiledownindicates gain in the bottom and loss in the top. Hence, the PT...
A parity-time (PT) symmetric system is a special non-Hermitian system of which its Hamiltonian possesses real eigenvalues. Recently, PT symmetry has been investigated extensively in photonic1,2,3,4,5,6,7,8,9,10,11,12,13 and optoelectronic14,15 systems, one of the main reasons being its...
