We predict that a photon condensate inside a dye-filled microcavity forms long-lived spatial structures that resemble vortices when incoherently excited by a focused pump orbiting around the cavity axis. The finely structured density of the condensates have a discrete rotational symmetry that is controlled by the orbital frequency of the pump spot and is phase coherent over its full spatial extent, despite the absence of any effective photon-photon interactions.

寻找光子凝聚中的漩涡

我们预测,当被围绕腔轴旋转的聚焦泵非相干地激发时,充满染料的微腔内的光子凝聚形成长寿命的空间结构,类似于漩涡。尽管没有任何有效的光子 - 光子相互作用,但凝聚物的精细结构密度具有离散的旋转对称性,该对称性由泵浦光斑的轨道频率控制,并且在其整个空间范围内是相位相干的。
