Metastability timescales near first-order transitions in driven-dissipative systems with hidden time-reversal symmetry are analytically predictable via purification of the steady state.
A stochastic unravelling that stays inside the permutation-symmetric subspace cuts simulation cost for N two-level emitters from O(N^5) to O(N^2) (or O(N) with extra symmetries) and extends to d-level emitters.
Emitter-emitter interactions allow individual nonlinear susceptibilities to appear as vibrational sidebands in the linear spectra of quantum emitter arrays and heterodimers.
