A quantum instanton method based on quasiprobability dynamics describes stationary states and asymptotic relaxation rates for large-spin collective systems, outperforming the Wigner approach by accounting for non-Gaussian fluctuations.
Quantum jump correlations and waiting-time distributions in long-range dissipative spins display clear signatures of the paramagnetic-to-ferromagnetic transition when analyzed with tilted Lindbladian, cluster mean-field, and cumulant expansion methods.
Aligning an exceptional point with a dissipative phase transition in an extended open Dicke model amplifies critical fluctuations and modifies critical exponents through EP-induced Jordan-block dynamics.
