Understanding and characterizing phase transitions in driven-dissipative systems constitutes a new frontier for many-body physics1–8. A generic feature of dissipative phase transitions is a vanishing gap in the Liouvillian spectrum9, which leads to long-lived deviations from the steady state as the system is driven towards the transition. Here, we show that photon correlation measurements can be used to characterize the corresponding critical slowing down of non-equilibrium dynamics. We focus… 
Experimental observation of a dissipative phase transition in a multi-mode many-body quantum system
We characterize the dissipative phase transition in a driven dissipative Bose-Einstein condensate of neutral atoms. Our results generalize the work on dissipative nonlinear Kerr resonators towards

This work studies the driven-dissipative Bose-Hubbard model, a minimal description of numerous atomic, optical, and solid-state systems in which particle loss is countered by coherent driving and establishes new connections between traditional techniques from many-body physics (functional integrals) and quantum optics (the system-size expansion).
