- Authors: Eduardo Zubizarreta Casalengua, Elena del Valle and Fabrice P. Laussy
- Abstract summary: We discuss two-photon correlations from the side peaks that are formed when a two-level system emitter is driven coherently.
We show that their combination leads to a neat picture compatible with perturbative two-photon scattering.
This should help to control, enhance and open new regimes of multiphoton emission.

- Abstract: We discuss two-photon correlations from the side peaks that are formed when a
two-level system emitter is driven coherently, with a detuning between the
driving source and the emitter (quasi-resonance fluorescence). We do so in the
context of the theories of frequency-resolved photon correlations and
homodyning, showing that their combination leads to a neat picture compatible
with perturbative two-photon scattering that was popular in the early days of
quantum electrodynamics. This should help to control, enhance and open new
regimes of multiphoton emission. We also propose a way to evidence the quantum
coherent nature of the process from photoluminescence only, through the
observation of a collapse of the symmetry of the lineshape accompanied by a
surge of its intensity of emission. We discuss several of our results in the
light of recent experimental works.

We investigate an extended Jaynes-Cummings model where two photon modes are coupled off-resonantly to a quantum emitter.
We identify few-photon scattering mechanisms that lead to a full inversion of the emitter while transferring off-resonant photons from one mode to another.
Our results can be understood as quantized analogue of the recently developed off-resonant quantum control scheme known as Swing-UP of quantum EmitteR.

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.

Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.
One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them.
Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

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.

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.
