SUMMARY: Bose-Einstein Condensates of light: Thermodynamics\, Fluctuations
  and Evolution - Frank Vewinger (University of Bonn)

DESCRIPTION:Bose-Einstein condensation has been studied in different syste
 ms 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 par
 ticle reservoir\, and grandcanonical experimental conditions can approxima
 tely be realized in this system\, where the condensate shows large number 
 fluctuations.\n\nIn 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. Follow
 ing 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.\n
