Results Parity-time-symmetric sine-Gordon model. We consider a class of one-dimensional (1D) quantum systems described by the field theory Hamiltonian Z H^ ¼ & dx 'v 2p K @x ^y2 þ 1 K @x f^ 2 ! þ ' Vðf^Þ ; ð1Þ where f^ is a scalar field, @x...
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...
Here, we experimentally realize parity-time-symmetric optics on a chip at the 1,550 nm wavelength in two directly coupled high-Q silica-microtoroid resonators with balanced effective gain and loss. With this composite system, we further implement switchable optical isolation with a non-reciprocal ...
Parity-time symmetric quantum critical phenomena Synthetic nonconservative systems with parity-time (PT) symmetric gain-loss\nstructures can exhibit unusual spontaneous symmetry breaking that accompanies\...

A parity-time–symmetric optoelectronic oscillator was demonstrated without the use of a narrowband microwave or optical filter. An optoelectronic oscillator (OEO) is a hybrid microwave and photonic system incorporating an amplified positive feedback loop to enable microwave oscillation to generate a high...
2. The Eigenvalue Problem and PT -Symmetric Evolution We start by considering the simple case of a massless Fermion moving in one dimension, which has a linear dispersion relation as shown in Figure 1a. The right and left moving particles form a two-state system { | L 〉 , | R 〉...
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 ...
Parity-time-symmetric microring lasers The ability to control the modes oscillating within a laser resonator is of fundamental importance. In general, the presence of competing modes can be detrimental to beam quality and spectral purity, thus leading to spatial as well as te... H Hodaei,MA ...
We propose nonlinear parity-time symmetric circuits to deliver robust wireless power transfer even as a device is rapidly moving. Here we review the ... S Assawaworrarit,S Fan - International Conference on Metamaterials & Nanophotonics Metanano: St Petersburg 被引量: 0发表: 2020年 Nonreciprocal...
