AI 中文摘要

极化激元是混合光-物质准粒子,为动态调控多种凝聚态系统提供了通用平台。传统极化激元平台依赖直接偶极耦合,但受光学选择定则和太赫兹腔的限制,难以调控偶极禁戒或拉曼活性的晶格与自旋激发。本文提出理论平台以实现连续波磁子-拉曼声子-极化激元(MRP)凝聚:在连续波横向激光泵浦下,将包含强耦合磁子和拉曼活性声子(MRP)模式的磁性介质嵌入光学微腔,推导了稳态相图,证明临界条件下存在不同MRP凝聚相的特征。此外,由于裸磁子频率可通过外磁场调谐,横向泵浦频率和外磁场依赖的磁子可作为高度灵活的调控参数,用于探索和控制腔量子光学、晶格动力学与量子磁学交叉领域的宏观量子现象。

英文摘要

Polaritons---hybrid light-matter quasiparticles---provide a versatile platform for dynamically controlling a wide range of condensed matter systems. While conventional polaritonic platforms rely on direct dipole coupling, controlling dipole-forbidden or Raman-active lattice and spin excitations remains challenging due to optical selection rules and the limitations of THz cavities. Here, we propose a theoretical platform for realizing a continuous-wave magnon--Raman phonon--polariton condensate. By embedding a magnetic medium hosting strongly coupled magnon and Raman-active phonon (MRP) modes inside an optical microcavity under continuous-wave transverse laser pumping, we derive the stationary-state phase diagram and demonstrate the emerging signature of distinct MRP condensation phases under critical conditions. Furthermore, since the bare magnon frequency is tunable via an external magnetic field, we show that the transverse pump frequency and the external magnetic field-dependent magnon simultaneously as highly flexible control parameters for exploring and controlling macroscopic quantum phenomena at the interface of cavity quantum optics, lattice dynamics, and quantum magnetism.
