Multimode cavity QED description of photonic Bose-Einstein condensation — •David Steinbrecht1, Robert Bennett1,2, and Stefan Yoshi Buhmann1,2 — 1University of Freiburg, Germany — 2Freiburg Institute for Advanced Studies (FRIAS), Germany
Photonic Bose–Einstein condensation is a novel quantum state of light that arises when a laser-driven ensemble of dye molecules thermalises with light inside a cavity [1]. We are developing a first-principles description of the spatiotemporal structure of the phenomenon on the basis of multimode cavity QED. In our model, the molecule–light interactions are described in an open systems approach that quantifies spontaneous decay, cavity losses and intramolecular channels. The spatial mode structure is determined in terms of the electromagnetic Green’s tensor [2].
