• Abstract summary: We evaluate the exact dipole coupling strength between a single emitter and the radiation field within an optical cavity. Our model allows one to freely vary the resonance frequency of the cavity, the frequency of light or atomic transition addressing it and the design wavelength of the dielectric mirror. For very short cavities, the effective length used to determine their mode volume and the lengths defining their resonances are different, and also found to diverge appreciably from their geometric length.

• Abstract: We evaluate the exact dipole coupling strength between a single emitter and the radiation field within an optical cavity, taking into account the effects of multilayer dielectric mirrors. Our model allows one to freely vary the resonance frequency of the cavity, the frequency of light or atomic transition addressing it and the design wavelength of the dielectric mirror. The coupling strength is derived for an open system with unbound frequency modes. For very short cavities, the effective length used to determine their mode volume and the lengths defining their resonances are different, and also found to diverge appreciably from their geometric length, with the radiation field being strongest within the dielectric mirror itself. Only for cavities much longer than their resonant wavelength does the mode volume asymptotically approach that normally assumed from their geometric length.

  We experimentally investigate the transition from cavity to waveguide QED. We tailor the spectral density of modes of the resonator while remaining in the strong coupling regime.

  cavity photons and ferromagnetic spins excitations can exchange information coherently in hybrid architectures. Speed enhancement is usually achieved by optimizing the geometry of the electromagnetic cavity. We show that the geometry of the ferromagnet plays also an important role, by setting the fundamental frequency of the magnonic resonator.

  We study the collective emission of a beam of atomic dipoles into an optical cavity. By developing a theoretical description of the coupled atom-cavity dynamics we analyze the stationary atomic configurations. We find that the pulling is small if the cavity linewidth is much larger than the collective linewidth of the atomic beam.
