• Abstract summary: We extend the Dicke model to elucidate the influence of nuclear motion on superradiant emission. Our simulations reveal a new time scale attributed to the population leakage of the dark, subradiant states. These findings impact how superradiant states and molecular degrees of freedom can be leveraged and utilized in quantum optical systems.

• Abstract: Superradiance, in which the collective behavior of emitters can generate enhanced radiative decay, was first predicted by a model, now known as the Dicke model, that contains a collection of two-level systems (the emitters) all interacting with the same photonic mode. In this article, we extend the original Dicke model to elucidate the influence of nuclear motion on superradiant emission. Our dynamical simulations of the combined electronic, nuclear, and photonic system reveal a new time scale attributed to the population leakage of the dark, subradiant states. Furthermore, this dark state emission pathway can be controlled by tuning the nuclear potential energy landscape. These findings impact how superradiant states and molecular degrees of freedom can be leveraged and utilized in quantum optical systems.

  We study subradiance in a Bose-Einstein condensate positioned at the mode crossing of two optical cavities. metastable density structures that suppress emission into one cavity mode prevent relaxation to the stationary, superradiant grating. We reproduce these dynamics by a quantum mean field model, suggesting that subradiance shares characteristics with quasi-stationary states predicted in other long-range interacting systems.

• Directional spontaneous emission in photonic crystal slabs [49.1574468325115]
  Spontaneous emission is a fundamental out-of-equilibrium process in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations. One way to modify these photon-mediated interactions is to alter the dipole radiation patterns of the emitter, e.g., by placing photonic crystals near them. Our study delves into the interaction between these directional emission patterns and the aforementioned variables, revealing the untapped potential to fine-tune collective quantum optical phenomena.

  Dicke superradiance describes the collective radiative decay of a fully inverted ensemble of two-level atoms. We experimentally investigate this effect for a chiral, i.e.,direction-dependent light--matter coupling. Our results shed light on the collective radiative dynamics of cascaded quantum many-body systems.

We show that it is modulated in time, and that the presence of the oscillating mirror can enhance or inhibit the decay rate.
