- Abstract: We calculate the second-order correlation function for the atomic
fluorescence in the two-photon resonance operation of a driven dissipative
Jaynes-Cummings oscillator. We employ a minimal four-level model comprising the
driven two-photon transition alongside two intermediate states visited in the
dissipative cascaded process, in the spirit of [S. S. Shamailov et al., Opt.
Commun. 283, 766 (2010)]. We point to the difference between the output of a JC
oscillator exhibiting two-photon blockade and the scattered field of ordinary
resonance fluorescence, and discuss the quantum interference effect involving
the intermediate states, which is also captured in the axially transmitted
light. The spectrum and intensity correlation of atomic emission explicitly
reflect the particulars of the cascaded model.

We explore the statistical behavior of the light emanating from a coherently driven Jaynes-Cummings (JC) oscillator operating in the regime of multiphoton blockade.
We find that monitoring different quadratures of the cavity field in conditional homodyne detection affects the times waited between successive photon counter clicks''
Despite the fact that the steady-state cavity occupation is of the order of a photon, monitoring of the developing bimodality also impacts on the ratio between the emissions directed along the two decoherence channels.

Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement.
We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

We show that their combination leads to a neat picture compatible with perturbative two-photon scattering.

In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics.
Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
