Steffi (or rather her finger) explaining the experiment

Experimental setup and origin of the fluctuations

View at the experiment: The photons are trapped between two mirrors, and interact with the dye molecules, visible by the orange fluorescence. From the statistics of the outcoupled light we can determine the fluctuations. The fluctuations result from the interconversion of photons and excited dye molecules and vice versa (Inset).

Onsager Regression Theorem

Concept of the experiment: A condensate of photons (small sphere) is coupled to a large bath depicted by the red sphere. What happens to the condensate when the bath is disturbed, and how is this connected to the fluctuations of the bath?
