systems, and discuss how this can be employed to obtain physical intuition. Focusing on a specific
model of a non-linear driven Kerr cavity, we discuss the connections between spectral functions
changing sign and population inversion in the steady state. Surprisingly, we find that dissipation
can change the sign of spectral functions, with direct physical implications, even in absence of steady
state population inversion
