Bose-Einstein condensation has been studied in different systems in the last years. One of them are photons trapped in a cavity, where thermalization is achieved by thermal contact to a dye medium. Unlike the “usual” atomic BEC , here the dye molecules serve both as a heat and a particle reservoir, and grandcanonical experimental conditions can approximately be realized in this system, where the condensate shows large number fluctuations.

In my talk, I will give an overview on the properties of the photon condensate. First, I will give an introduction on the photon BEC , and then discuss the thermodynamic properties of the photons. Following this, I will present measurements on the dynamical properties of the condensate, including the large number fluctations expected in the grand canonical regime and the formation dynamics of the condensate.
