Counting statistics for Dicke-Superradiance — •Wassilij Kopylov, Clive Emary, and Tobias Brandes — TU Berlin, Institute of Theoretical Physics, Deutschland

We consider the Dicke-Hamiltonian valid in a rotating frame and couple it to a dissipative zero- temperature bath. We derive a cumulant generating function for emitted photons using the P - representation of the master equation with counting field for this model in the thermodynamic limit. The macroscopic occupation in the superradiant case is determined by the linear terms in the master equation.
