Title: Superradiant emission of a thermal atomic beam into an optical cavity
Authors: Simon B. J\"ager, Haonan Liu, John Cooper, Travis L. Nicholson, and Murray J. Holland
Abstract summary: We theoretically analyze the collective dynamics of a thermal beam of atomic dipoles that couple to a single mode when traversing an optical cavity. We derive a semiclassical model and determine the onset of superradiant emission and its stability. We show that both superradiant phases are robust against free-space spontaneous emission and $T$ dephasing processes.

Abstract: We theoretically analyze the collective dynamics of a thermal beam of atomic dipoles that couple to a single mode when traversing an optical cavity. For this setup we derive a semiclassical model and determine the onset of superradiant emission and its stability. We derive analytical expressions for the linewidth of the emitted light and compare them with numerical simulations. In addition, we find and predict two different superradiant phases; a steady-state superradiant phase and a multi-component superradiant phase. In the latter case we observe sidebands in the frequency spectrum that can be calculated using a stability analysis of the amplitude mode of the collective dipole. We show that both superradiant phases are robust against free-space spontaneous emission and $T_2$ dephasing processes.

Floquet Engineering of Non-Equilibrium Superradiance [0.0]
We show the emergence of a non-equilibrium superradiant phase in the dissipative Rabi-Dicke model. This phase is characterized by a photonic steady state that oscillates with a frequency close to the cavity frequency. We propose to use this Floquet-assisted superradiant phase to obtain controllable optical gain for a laser-like operation.

Collective emission of an atomic beam into an off-resonant cavity mode [1.5749416770494706]
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.

Finite temperature spectrum at the symmetry-breaking linear-zigzag transition [0.0]
We investigate the normal mode spectrum of a trapped ion chain at the symmetry-breaking linear to zigzag transition and at finite temperatures. The expected mode softening at the critical point, a signature of the second-order transition, is not observed. Our study could prove important for implementing ground-state laser cooling close to the critical point.

Multimode-polariton superradiance via Floquet engineering [55.41644538483948]
We consider an ensemble of ultracold bosonic atoms within a near-planar cavity, driven by a far detuned laser. We show that a strong, dispersive atom-photon coupling can be reached for many transverse cavity modes at once. The resulting Floquet polaritons involve a superposition of a set of cavity modes with a density of excitation of the atomic cloud.
