论文摘要
我们介绍了一个经典的相思模型，以描述多模光子冷凝物，该模型通过反复的吸收和染料分子再发射的热量化。热平衡是通过波动散落关系来表达的，该关系将能量阻尼与自发发射波动联系起来。我们将模型应用于光子约瑟夫森连接（两个耦合井），并将模型应用于光子冷凝物的一维阵列和二维阵列。在零泵送和空腔损耗的极限下，我们恢复了热平衡结果，但是在规范状态下弱驱动的触及式情况下，我们发现相对于理想的玻色气体，密度和相位波动被抑制。
We introduce a classical phasor model for the description of multimode photon condensates that thermalize through repeated absorptions and reemissions by dye molecules. Thermal equilibrium is expressed through the fluctuation-dissipation relation that connects the energy damping to spontaneous emission fluctuations. We apply our model to a photonic Josephson junction (two coupled wells) and to one- and two-dimensional arrays of photon condensates. In the limit of zero pumping and cavity losses, we recover the thermal equilibrium result, but in the weakly driven-dissipative case in the canonical regime, we find suppressed density and phase fluctuations with respect to the ideal Bose gas.
