Description
We generalize Glauber’s theorem to quantum fields generated by classical sources, including axion dark matter and gravitational waves. In quantum optics, Glauber’s theorem states that a classical current produces quantized photons in a coherent state. Likewise, the linearity of the inverse Primakoff and Gertsenshtein effects leads to coherent photon states in resonant cavities driven by classical dark matter or gravitational-wave fields. We also introduce thermal coherent states as a more realistic description of resonators employed in axion and gravitational-wave detectors. Finally, we derive a general solution for squeezed graviton states produced during black hole mergers.
