论文摘要
对于平衡系统，热波动的幅度与对外部扰动的耗散反应密切相关。已经描述了在各个域中的材料颗粒中描述了这种波动散落的关系。在这里，我们通过实验探测数量波动的关系与与染料储层相连的光子的玻璃体冷凝物之间的关系，这表明了光的量子气体的波动 - 隔离关系。观察到的量表因子与环境温度的一致性都直接证实了光凝结物的热性质，并证明了玻色 - 内斯坦冷凝物的波动 - 散落定理的有效性。
For equilibrium systems, the magnitude of thermal fluctuations is closely linked to the dissipative response to external perturbations. This fluctuation-dissipation relation has been described for material particles in a wide range of fields. Here we experimentally probe the relation between the number fluctuations and the response function for a Bose-Einstein condensate of photons coupled to a dye reservoir, demonstrating the fluctuation-dissipation relation for a quantum gas of light. The observed agreement of the scale factor with the environment temperature both directly confirms the thermal nature of the optical condensate and demonstrates the validity of the fluctuation-dissipation theorem for a Bose-Einstein condensate.
