我们预测，一个充满染料的微腔内的光子凝聚体形成长寿命的空间结构，类似于漩涡时，非相干激发的聚焦泵绕腔轴旋转。精细结构的密度的凝聚体具有离散的旋转对称性，这是由泵点的轨道频率控制，并在其整个空间范围内的相位相干，尽管没有任何有效的光子-光子相互作用。
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.
