In the subradiant regime of a bad-cavity laser, a dissipative phase transition maps to a switch from detailed-balance Markov chains to ones with time-asymmetric currents and N-scaling entropy production, producing observable self-pulsing.

The maximum photon emission rate in atomic ensembles scales universally as atom number times optical depth at fixed density, unifying ordered and disordered systems from independent emission to the Dicke limit.
In a minimal model of partially pumped atomic ensembles, collective dissipation induces interference that allows tuning linewidth from size-independent to extensive and photon statistics from antibunched to bunched via phase and pump rate.
Superradiant emission remains asymptotically robust to strong disorder in waveguide QED arrays because atoms spontaneously self-organize their spin states to optimize constructive interference.
