• Abstract: We study the propagation of strongly interacting Rydberg polaritons through an atomic medium in a one-dimensional optical lattice. We derive an effective single-band Hubbard model to describe the dynamics of the dark state polaritons under realistic assumptions. Within this model, we analyze the driven-dissipative transport of polaritons through the system by considering a coherent drive on one side and by including the spontaneous emission of the metastable Rydberg state. Using a variational approch to solve the many-body problem, we find strong antibunching of the outgoing photons despite the losses from the Rydberg state decay.

  We study the out-of-equilibrium dynamics of Rydberg exciton-polaritons fueled by their characteristic long-range non-local interactions. We trace this phenomenon back to the destructive interference between the polariton state and the pump in a driven ensemble. These findings provide new opportunities for exploring the emerging field of long-range interacting gases through Rydberg exciton-polaritons.

  Polarons arise from the self-trapping interaction between electrons and lattice distortions in a solid. We present a microscopic model that exhibits a diverse range of dynamic behavior, arising from the intricate interplay between excitation-phonon coupling terms. This work contributes to the understanding of polaron dynamics with their potential applications in coherent quantum transport.

  We employ a Rydberg quantum simulator to experimentally demonstrate strongly correlated spin transport in anisotropic Heisenberg magnets. In our approach, the motion of magnons is controlled by an induced spin-exchange interaction through Rydberg dressing. As the most prominent signature of a giant anisotropy, we show that nearby Rydberg excitations form distinct types of magnon bound states.

  We experimentally investigate individual spin dynamics in a two-dimensional ensemble of electron spins on the surface of a diamond crystal. We show that this anomalously slow relaxation rate is due to the presence of strong dynamical disorder. Our work paves the way towards microscopic study and control of quantum thermalization in strongly interacting disordered spin ensembles.

• Many-body radiative decay in strongly interacting Rydberg ensembles [0.0]
  When atoms are excited to high-lying Rydberg states they interact strongly with dipolar forces. We show that these interactions have also a significant impact on dissipative effects caused by the inevitable coupling of Rydberg atoms to the surrounding electromagnetic field. We discuss how this collective dissipation - stemming from a mechanism different from the much studied super- and sub-radiance - accelerates decoherence and affects dissipative phase transitions in Rydberg ensembles.

  We consider an ensemble of Alkali atoms that are continuously optically pumped and probed. Due to the collective scattering of photons at large optical depth, the steady state of atoms does not correspond to an uncorrelated tensor-product state. We find and characterize regimes of Raman lasing, akin to the model of a superradiant laser.

We perform a detailed analysis of the phase diagram at half- and incommensurate fillings, in the mean-field approximation. We furthermore study the stability of the phases with respect to temperature within the mean-field approximation.

  We propose a novel scheme for coupling a Rydberg state to a stationary light polariton, based on a dual-V level scheme. We investigate the properties of the resulting stationary Rydberg polariton, and show that its form and its dispersion relation closely resemble that of the stationary light polariton of the underlying dual-V scheme.
