• Abstract: We theoretically investigate cooperative effects in cold atomic gases exhibiting both electric and magnetic dipole-dipole interactions, such as occurring for example in clouds of dysprosium atoms. We distinguish between the quantum degenerate case, where we take a many body physics approach and the quantum non-degenerate case, where we use the formalism of open system dynamics. For quantum non-degenerate gases, we illustrate the emergence of tailorable spin models in the high-excitation limit. In the low-excitation limit, we provide analytical and numerical results detailing the effect of magnetic interactions on the directionality of scattered light and characterize sub- and superradiant effects. For quantum degenerate gases, we study the interplay between sub- and superradiance effects and the fermionic or bosonic quantum statistics nature of the ensemble.

• Directional superradiance in a driven ultracold atomic gas in free-space [0.0]
  We study a dense ensemble illuminated by a strong coherent drive while interacting via dipole-dipole interactions. Although the steady-state features some similarities to the reported superradiant to normal non-induced transition, we observe significant qualitative and quantitative differences. We develop a simple theoretical model that explains the scaling properties by accounting for interaction-equilibrium inhomogeneous effects and spontaneous emission.

  We explore cooperative dynamics of quantum emitters in an optical lattice that interact by radiating atomic matter waves. We demonstrate directional super- and subradiance from a superfluid phase with tunable radiative phase lags. We observe a coupling to collective bound states with radiation trapped at and between the emitters.

  Quasiparticles are emergent excitations of matter that underlie much of our understanding of quantum many-body systems. We take advantage of the clean setting of homogeneous quantum gases and fast radio-frequency control to manipulate Fermi polarons. We measure the decay rate and the quasiparticle residue of the driven polaron from the Rabi oscillations between the two internal states.

Such systems, arrays of two-level atoms (qubits) coupled to light being described by the classical Dicke model, have recently been realized in experiments with cold atoms and superconducting qubits.
