From Maxwell Equations to Bose-Einstein Condensation of Photons — •Tobias Rexin1, Carsten Henkel1, and Axel Pelster21Institut für Physik und Astronomie, Universität Potsdam, Germany — 2Hanse-Wissenschaftskolleg, Delmenhorst, Germany

Light confined in a microcavity [1] is described by Maxwell’s equations with appropriate boundary conditions. A careful analysis of the corresponding boundary value problem in oblate spheroidal coordinates provides a systematic approach to determine the underlying mode functions. In the paraxial approximation, this three-dimensional microcavity problem can be reduced to an effective two-dimensional trapped massive Bose gas. This result supports the heuristic derivation of Ref. [2], where even the Bose-Einstein condensation of these massive photons was observed. We present recent calculations of the mode structure and correlation functions in thermodynamic equilibrium.
