- Abstract summary: We derive an analytical expression for the equation of motion of the photon-photon correlation function inside a dye-filled microcavity.
This allows us to derive the coherence time of the photonic modes and identify a nonmonotonic dependence of the temporal coherence of the condensed light with the cutoff frequency of the microcavity.

- Abstract: The study of temporal coherence in a Bose-Einstein condensate of photons can
be challenging, especially in the presence of correlations between the photonic
modes. In this work, we use a microscopic, multimode model of photonic
condensation inside a dye-filled microcavity and the quantum regression
theorem, to derive an analytical expression for the equation of motion of the
photon-photon correlation function. This allows us to derive the coherence time
of the photonic modes and identify a nonmonotonic dependence of the temporal
coherence of the condensed light with the cutoff frequency of the microcavity.

We study the frequency-resolved density response of a photon Bose-Einstein condensate coupled to a bath of dye molecules by time-periodic driving.
We find that as the photon number increases, the response of the coupled condensate-bath system transitions from overdamped to resonant behavior.

Detection of single, itinerant microwave photons is an important functionality for emerging quantum technology applications.
It was demonstrated that a double quantum dot (DQD) coupled to a microwave resonator can act as an efficient and continuous photodetector.
Here we theoretically investigate, in the same system, the fluctuations of the photocurrent through the DQD for a coherent microwave drive of the resonator.

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.
