标题： Many-Body Photon Blockade and Quantum Light Generation from Cavity Quantum Materials

摘要： 光子与光学腔体内量子材料的强耦合 regime 已成为利用光操控物质状态的有前景环境。 在此，我们表明光子见证了腔内量子电动力学对材料的修改，导致通过腔体的光具有深刻非经典的特性。 通过将量子光学输入输出关系推广到关联的量子材料，我们研究了二阶光子相干性 g2(t)，并证明透射光子的抗聚束现象是光诱导腔嵌入材料变化的直接证据。 我们表明接近量子临界点的材料可以实现集体多体光子阻塞，从而通过利用强物质涨落生成单光子或爱因斯坦-波多尔斯基-罗森对。 我们的发现为探测和利用腔嵌入量子材料作为量子光源提供了新途径，作为基于光子的计算和量子传感的资源。 显示英文摘要

摘要： The strong coupling regime of photons and quantum materials inside optical cavities has emerged as a promising environment for manipulating states of matter with light. Here, in turn, we show that photons bear witness to cavity quantum-electrodynamical modifications of the material, leading to profoundly non-classical properties of light passing through the cavity. By generalizing quantum-optical input-output relations to correlated quantum materials, we study the second-order photon coherence g2(t) and demonstrate that antibunching of transmitted photons serves as direct evidence of light-induced changes to the cavity-embedded material. We show that materials near a quantum critical point can realize a collective many-body photon blockade, enabling the generation of single photons or Einstein-Podolsky-Rosen pairs via leveraging strong matter fluctuations. Our findings provide new routes for interrogating and harnessing cavity-embedded quantum materials as quantum light sources, as a resource for photon-based computation and quantum sensing.
