AI 中文总结
该论文围绕超共振展开，其定义为辐射线宽因辐射通道相消干涉趋于零而裸单通道耦合仍大。介绍其典型实现，逐场研究相关现象并提炼规则，还区分了超共振与相干增强、整数 - 可公度性锁定等概念，明确其与黑洞超辐射中放大的不同。
AI 中文摘要
超共振已分别用于声学腔阵列的集体模式（托尔斯泰）、光子学中介质谐振器的极高品质因数状态以及磁振子学中的磁振子 - 极化子束缚态，现在可互换应用于物理上不同的现象。本综述围绕一个精确的、与场无关的定义展开：一种模式，其辐射线宽通过其辐射通道之间的相消干涉被驱动至零，即\(\gamma_{\rm rad}/\gamma_{\rm rad}^{\rm cl}\to0\)，而裸单通道耦合仍然很大。典型实现是两种模式共享一个连续体的弗里德里希 - 温特根情景。相同的非厄米本征值结构出现在托尔斯泰的声学阵列、连续体中的光子束缚态和准 BIC 超腔模式、无偶极子、相干完美吸收体的暗模式、例外点附近的奇偶时间对称器件、磁振子暗模式和拓扑边缘模式中。我们逐场研究这些实现，并提炼出可转移的设计规则和品质因数。然后，我们将超共振与共享“超 - ”前缀的两个家族区分开来：相干增强，其中与连续体的耦合是集体增加而不是抑制（迪克超辐射、超散射、回音壁模式）；以及整数 - 可公度性锁定（平均运动、波 - 粒子和弗洛凯共振）。黑洞超辐射中的放大同样被区分开来。
英文摘要
Super-resonance has been coined independently for collective modes of acoustic cavity arrays (Tolstoy), extreme high-$Q$ states of dielectric resonators in photonics, and magnon-polaron bound states in magnonics, and is now applied interchangeably to physically distinct phenomena. We organise this review around the one usage admitting a precise, field-agnostic definition: a mode whose radiative linewidth is driven toward zero by destructive interference among its radiation channels, $γ_{\rm rad}/γ_{\rm rad}^{\rm cl}\to0$, while the bare single-channel coupling remains large. The canonical realisation is the Friedrich-Wintgen scenario of two modes sharing a continuum. The same non-Hermitian eigenvalue structure recurs in Tolstoy's acoustic arrays, photonic bound states in the continuum and quasi-BIC supercavity modes, anapoles, dark modes of coherent perfect absorbers, parity-time-symmetric devices near exceptional points, magnonic dark modes, and topological edge modes. We survey these realisations field by field and distil transferable design rules and figures of merit. We then disambiguate super-resonance from two families sharing the "super-" prefix: coherent enhancement, in which coupling to the continuum is collectively increased rather than suppressed (Dicke super-radiance, superscattering, whispering-gallery modes); and integer-commensurability locking (mean-motion, wave-particle, and Floquet resonances). Amplification, as in black-hole super-radiance, is likewise distinguished.
