- Abstract: We discuss the conditional measurement of field amplitudes by a nonclassical
photon sequence in the Jaynes-Cummings (JC) model under multiphoton operation.
We do so by employing a correlator of immediate experimental relevance to
reveal a distinct nonclassical evolution in the spirit of [G. T. Foster et al.,
Phys. Rev. Lett. 85 3149 (2000)]. The correlator relies on the complementary
nature of the pictures obtained from different unravelings of a JC source
master equation. We demonstrate that direct photodetection entails a
conditioned separation of timescales, a quantum beat and a semiclassical
oscillation, produced by the coherent light-matter interaction in its
strong-coupling limit. We single the quantum beat out in the analytical
expression for the waiting-time distribution, pertaining to the particle nature
of the scattered light, and find a negative spectrum of quadrature amplitude
squeezing, characteristic of its wave nature for certain operation settings.
Finally, we jointly detect the dual aspects through the wave-particle
correlator, showing an asymmetric regression of fluctuations to the steady
state which depends on the quadrature amplitude being measured.

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.

We consider an ensemble of Alkali atoms that are continuously optically pumped and probed.
Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state.
We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator.
We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.

We study a system of two interacting, non-indentical quantum emitters driven by a coherent field.
We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters.
This can be exploited for applications such as superresolution imaging of point-like sources.

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.
