我们研究了一种腔量子电动力学效应，其中二维自由旋转光学偶极子的排列是由它们与腔场的集体耦合驱动的。通过利用一组旋转偶极子与聚合物的形式等价，我们计算了耦合光物质系统的配分函数，并证明了它在各向同性取向的束状状态和所有偶极子排列的拉伸状态之间表现出二阶相变。这种跃迁表现为极化子模式共振的强度依赖位移。我们的工作处于腔量子电动力学和量子光力学的十字路口，必须成为腔量子电动力学和量子光力学的十字路口。
We investigate a cavity quantum electrodynamic effect, where the alignment of two-dimensional freely rotating optical dipoles is driven by their collective coupling to the cavity field. By exploiting the formal equivalence of a set of rotating dipoles with a polymer we calculate the partition function of the coupled light-matter system and demonstrate that it exhibits a second order phase transition between a bunched state of isotropic orientations and a stretched one with all the dipoles aligned. Such a transition manifests itself as an intensity-dependent shift of the polariton mode resonance. Our work, lying at the crossroads of cavity quantum electrodynamics and quantum optomechanics has to become the crossroads between cavity quantum electrodynamics and quantum optomechanics.
