近日，德国马克斯·普朗克光科学研究所Vahid Sandoghdar团队研究了通过共同光子模式的分子杂交。该项研究成果发表在2025年7月30日出版的《美国科学院院刊》杂志上。

当原子和分子彼此靠得非常近时，它们会发生热杂交并形成键。

在这项工作中，研究组证明了分子甚至可以通过由光学微腔的共享模式介导的远场电磁相互作用杂交。他们揭示了真空拉比分裂的集体增强，并研究了谐振和色散状态下由腔介导耦合产生的超态和次态。此外，研究组还证明了在新的光学化合物的基态和激发态之间出现的双光子跃迁。他们的实验数据与塔维斯-卡明斯哈密顿量的预测非常吻合，为实现光-物质混合材料打开了大门。

Abstract: Atoms and molecules usually hybridize and form bonds when they come in very close proximity of each other. In this work, we show that molecules can hybridize even through far-field electromagnetic interactions mediated by the shared mode of an optical microcavity. We discuss a collective enhancement of the vacuum Rabi splitting and study super- and subradiant states that arise from the cavity-mediated coupling both in the resonant and dispersive regimes. Moreover, we demonstrate a two-photon transition that emerges between the ground and excited states of the new optical compound. Our experimental data are in excellent agreement with the predictions of the Tavis–Cummings Hamiltonian and open the door to the realization of hybrid light–matter materials.
