• Authors: Thomas F. Allard, Guillaume Weick
• Abstract summary: We study the interplay between disorder and light-matter coupling by considering a disordered one-dimensional chain of lossy dipoles coupled to a multimode optical cavity. Such a system, hosting polaritonic excitations, may be realized experimentally in a wide range of platforms under strong light-matter coupling.

• Abstract: We study the interplay between disorder and light-matter coupling by considering a disordered one-dimensional chain of lossy dipoles coupled to a multimode optical cavity, through a microscopically derived Hamiltonian. Such a system, hosting polaritonic excitations, may be realized experimentally in a wide range of platforms under strong light-matter coupling. By analyzing both the eigenspectrum and the driven-dissipative transport properties of our system, we find that in the strong-coupling regime, increasing disorder leads almost uncoupled dark states to acquire a photonic part, allowing them to inherit polaritonic long-range transport characteristics. Crucially, we show that this disorder-enhanced transport mechanism is increasingly noticeable when the considered dipoles are lossier.

  We study the cooperative radiance of moir'e excitons that is demonstrated to emerge from the deep subwavelength nature of the moir'e lattice. Our results show that interlayer moir'e excitons offer a unique platform for exploring cooperative optical phenomena in strongly interacting many-body systems.

  We show that mirrors in the direction transverse to the chain may act as effective defects, leading to the emergence of Tamm edge states. Considering a topological chain, we demonstrate that such transverse mirrors may also protect edge states against the effects of the strong light-matter coupling.

  Long-range interactions are a key resource in many quantum phenomena and technologies. We show how to design the polaritonic bands of these atomic metamaterials to feature a pair of frequency-isolated Weyl points. These Weyl excitations can thus mediate interactions that are simultaneously long-range, due to their gapless nature; robust, due to the topological protection of Weyl points; and decoherence-free, due to their subradiant character.

• Dissipative stabilization of maximal entanglement between non-identical emitters via two-photon excitation [49.1574468325115]
  Two non-identical quantum emitters, when placed within a cavity and coherently excited at the two-photon resonance, can reach stationary states of nearly maximal entanglement. We show that this mechanism is merely one among a complex family of phenomena that can generate both stationary and metastable entanglement when driving the emitters at the two-photon resonance.

  We investigate collective phenomena in a system of many particles in a harmonic trap coupled to a homogeneous quantum cavity field. The cavity field mediates pairwise long-range interactions and enhances the effective mass of the particles. The light-matter interaction also modifies the photonic properties of the polariton system, as the ground state is populated with bunched photons.

  Electromagnetically induced transparency (EIT) is a phenomenon that can provide strong and robust interfacing between optical signals and quantum coherence of electronic spins. We show that EIT can be established with high visibility also in this material platform upon careful design of the measurement geometry. Our work provides an understanding of EIT in multi-level systems with significant inhomogeneities, and our considerations are valid for a wide array of defects in semiconductors.

  We investigate the exciton complexes photoluminescence, dynamics and photon statistics in the concurrent strong weak coupling regime. We demonstrate the strong and weak coupling can coexist dynamically, as a form of intermediate regime mediated by phonon scattering. This study suggests our device has potential for new and subtle cavity quantum electrodynamical phenomena, cavity enhanced indistinguishable single photon generation, and cluster state generation via the exciton-photon complexes for quantum networks.
