Multimode-polariton superradiance via Floquet engineering

  title={Multimode-polariton superradiance via Floquet engineering},
  author={Christian Johansen and Johannes Lang and Andrea Morales and Alexander Baumgarenter and Tobias Donner and Francesco Piazza},
We consider an ensemble of ultracold bosonic atoms within a near-planar cavity, driven by a far detuned laser whose phase is modulated at a frequency comparable to the transverse cavity mode spacing. 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 excitation of the atomic cloud. The mutual interactions between these modes lead to… Expand

Optomechanical atom-cavity interaction in the sub-recoil regime
We study the optomechanical interaction of a Bose–Einstein condensate with a single longitudinal mode of an ultra-high finesse standing wave optical resonator. As a unique feature the resonatorExpand
Steering matter wave superradiance with an ultranarrow-band optical cavity.
The instability boundary for the onset of matter wave superradiance is recorded and its main features are explained by a mean field model. Expand
Supermode-density-wave-polariton condensation with a Bose–Einstein condensate in a multimode cavity
The ability to observe and understand density-wave-polariton condensation in the few-mode-degenerate cavity regime and the potential to study similar questions in fully multimode cavities are demonstrated. Expand
Interacting Floquet polaritons
The production of Floquet polaritons provides a promising new route to the realization of ordered states of strongly correlated photons, including crystals and topological fluids, as well as quantum information technologies such as multimode photon-by-photon switching. Expand
Interaction-Induced Transparency for Strong-Coupling Polaritons.
This work considers the propagation under the condition of electromagnetically induced transparency and shows that a novel many-body phenomenon can appear due to strong, dissipative interactions between the polaritons, and predicts the interaction-induced transparency transition even at low polariton densities.

Strongly interacting polaritons in coupled arrays of cavities
Observing quantum phenomena in strongly correlated many-particle systems is difficult because of the short length- and timescales involved. Exerting control over the state of individual elementsExpand
