Quantum many-body dynamics of driven-dissipative Rydberg polaritons — •Tim Pistorius, Javad Kazemi, and Hendrik Weimer — Institut für theoretische Physik, Leibniz Universität Hannover, Deutschland

We develop a theory to describe the propagation of a light pulse through a lattice of Rydberg atoms using the polariton picture. A system of three-level atoms is coupled with a space-dependent probe and control field. A Bose-Hubbard-like model for the dark state polariton is obtained after a transformation in the Wannier basis. The analysis is done with the variational principle[1] which allows for the investigation of larger system sizes, long-range jumps, dissipative processes and also an implementation of the Rydberg blockade radius. We show the evolution of the output intensity and the dark state polariton occupation probability. The results are the first step towards the study of the behavior of the dark state polariton inside a lattice.
