Photonic Parity-Time (PT) symmetry takes advantage of these inherent losses, utilizing them in conjunction with balanced gain media to control eigenmode evolution. In this chapter, we review progress in PT-symmetric plasmonics, focusing on planar and coaxial geometries. We show how inclusion of ...
宇称-时间对称(Parity-Time-symmetry)理论由卡尔班德(Carl Bender)和他的合作者提出的,是基础物理学的研究热点。
-shaded surface represents the real part of the quasi-energyε. The intact PT symmetry of the arrangement is evidenced by the globally vanishing imaginary (Imag) part (orange). The right side shows that in addition to the projection of the bulk bands (blue), the edge band structure (...
parity-time symmetry; holographic principal; quantum simulation1. Introduction In the 1980s, Richard Feynman envisioned the advantage of using quantum mechanical systems to simulate quantum physics [1]. As most formulations of quantum mechanics consider the systems to be governed by Hermitian Hamiltonian...
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 ...
A detailed analysis of the proper- ties of the Floquet operator and the generalized PT symmetry of the effective Hamiltonian is provided in Supplementary Section 2. Due to the non-orthogonality of the eigenstates of the Floquet operator, the intensity of any given state is no longer a ...
1PT symmetry-enabled linewidth manipulation Among various types of nonlinear processes (e.g., second-order χ(2)and third-order χ(3)susceptibility, stimulated Raman scattering, stimulated Brillouin scattering), we employ degenerate four-wave mixing (FWM) based on χ(3)for the NOSP. The degener...
parity–time symmetry; coupled optoelectronic oscillator; gain coefficient; coupling coefficient; orthogonal polarization; phase noise1. Introduction High-frequency microwave signals with high spectral purity are widely used in wireless communication, sensing, and radar [1]. Conventionally, high-frequency ...
