AI 中文摘要
近几十年来，基于两能级原子（分子）与光子构建和研究单个量子系统已取得重大进展。本文证明，MoMo键长仅为2.1Å的四重键合Mo₂单元，可在环境条件下作为本征发射器-谐振器分子量子系统，在两个钼原子之间捕获可见光光子，从而产生具有极小模式体积的强量子化局域电磁场。三种Mo₂配合物的共振荧光光谱表明，金属间Mo-Mo电荷转移跃迁与局域散射场相干耦合，呈现真空拉比分裂和莫洛三重态。单分子及N分子系综通过边带激发与散射光的共振耦合，产生覆盖宽波长范围的一系列离散光学模式，其极化激元跃迁与Ni₂基系统中观测到的完全一致。这些结果确立了Mo₂分子作为独立的发射器-谐振器集成量子系统，可利用常规光谱仪器在自由空间开展量子光学实验。本研究将量子电动力学拓展至分子科学，为金属-金属键、分子物理及光-物质相互作用提供新见解。
英文摘要
In recent decades, significant progress has been made in constructing and studying individual quantum systems based on two level atoms (molecules) and photons. Here we demonstrate that the quadruply bonded Mo2 unit, with a MoMo bond distance as short as 2.1A, functions as an innate emitter resonator molecular quantum system capable of trapping visible light photons between the two molybdenum atoms under ambient conditions, thereby generating an intense quantized local electromagnetic field with an extremely small mode volume. The resonance fluorescence spectra of three Mo2 complexes indicate that the intermetallic Mo-Mo charge transfer transition is coherently coupled to the local scattering field, exhibiting vacuum Rabi splitting and Mollow triplets. Resonant coupling of single molecules and N-molecule ensembles to the scattered light through sideband excitation produces a sequence of discrete optical modes spanning a broad wavelength range, with polaritonic transitions identical to those observed in Ni2 based systems. These results establish the Mo2 molecule as an independent emitter resonator integrated quantum system that enables quantum optical experiments in free space using conventional spectroscopic instrumentation. This work extends quantum electrodynamics into molecular science, providing new insights into metal metal bonding, molecular physics, and light matter interactions.
