title: Time-asymmetric fluctuations of light and the breakdown of detailed balance.
abstract: Temporal fluctuations of the light radiated by a photoemissive source are studied through the cross correlation of output fields. Whereas microscopic reversibility guarantees time-symmetric fluctuations in thermal equilibrium--where detailed balance holds--away from equilibrium time asymmetry is permitted. Examples of time asymmetry in cavity QED are reported.
