AI 中文摘要
腔磁子学正超越传统的相干自旋-光子杂化范式，转向对耗散与相干相互作用的受控工程、Floquet动力学以及量子涨落的研究。本展望文章考察了这些要素如何重塑集体动力学，并为量子态工程、输运和传感开辟新途径。我们讨论了耗散耦合和反$\mathcal{PT}$对称性在实现长寿命集体模式和增强光谱响应中的作用，并强调Floquet工程作为实现非互易输运和相位控制相互作用的手段。随后，我们回顾了量子磁子学的最新进展，从压缩和纠缠磁子态（包括热磁子的压缩）到制备磁子薛定谔猫态的前瞻性方案。我们还讨论了参数驱动和有源增益如何强烈改变杂化磁化率并放大磁子-光子响应。这些进展将腔磁子学的范围扩展到传统极化激元物理之外，使其成为传感、换能、自旋输运和混合量子技术的多功能平台。
英文摘要
Cavity magnonics is moving beyond the conventional paradigm of coherent spin--photon hybridization toward the controlled engineering of dissipative and coherent interactions, Floquet dynamics, and quantum fluctuations. This Perspective examines how these ingredients reshape collective dynamics and open new avenues for quantum state engineering, transport, and sensing. We discuss the role of dissipative coupling and anti-$\mathcal{PT}$ symmetry in enabling long-lived collective modes and enhanced spectral response, and highlight Floquet engineering as a means of engineering nonreciprocal transport and phase-controlled interactions. We then review recent progress in quantum magnonics, ranging from squeezed and entangled magnon states, including the squeezing of thermal magnons, to prospective schemes for preparing magnonic Schrödinger-cat states. We also discuss how parametric driving and active gain strongly modify hybrid susceptibilities and amplify magnon--photon response. These advances expand the scope of cavity magnonics beyond conventional polariton physics, establishing it as a versatile platform for sensing, transduction, spin transport, and hybrid quantum technologies.
