• Abstract: When axionic dark matter interacts with a static magnetic field, it can convert into photons with energy near the axion's mass. Classical analysis shows that incorporating a resonant cavity significantly enhances this conversion rate, forming the basis for many experiments aimed at detecting dark matter axions. However, one question remains: Does the axion-photon conversion rate increase for a single axion-photon transition? Answering this issue could lead to optimizations in searching for axions by integrating quantum measurement techniques. In this paper, we demonstrate that at the quantum level, single axion-photon transitions are amplified by the cavity's quality factor $Q$; even if dark matter particles lack coherence, the conversion rate is still enhanced. Furthermore, the quantum perspective reveals an additional factor of $\pi/2$ in the transition rate compared to the classical result. Additionally, we also provide an analysis of the scenario involving dark photon dark matter.

  No class-B quantum density-matrix model is available to date, capable of accurately describing coherence and photon correlations within a unified theory. Here we carry out a density-matrix theoretical approach for generic class-B lasers, and provide closed equations for the photonic and atomic reduced density matrix in the Fock basis of photons. This model enables the study of few-photon bifurcations and non-classical photon correlations in class-B laser devices, also leveraging quantum descriptions of coherently coupled nanolaser arrays.
