Scattering resonances and bound states for strongly interacting Rydberg polaritons

Przemysław Bienias, Soonwon Choi, Ofer Firstenberg +5 more

We provide a theoretical framework describing slow-light polaritons interacting via atomic Rydberg states. The method allows us to analytically derive the scattering properties of two polaritons. We identify parameter regimes where polariton-polariton interactions are repulsive. Furthermore, in the regime of attractive interactions, we identify multiple two-polariton bound states, calculate their dispersion, and study the resulting scattering resonances. Finally, the two-particle scattering properties allow us to derive the effective low-energy many-body Hamiltonian. This theoretical platform is applicable to ongoing experiments.We provide a theoretical framework describing slow-light polaritons interacting via atomic Rydberg states.

Effective Field Theory for Rydberg Polaritons

Michael J. Gullans, Jeff D. Thompson, Yang Wang +4 more

We develop an effective field theory (EFT) to describe the few- and many-body propagation of one-dimensional Rydberg polaritons. We show that the photonic transmission through the Rydberg medium can be found by mapping the propagation problem to a nonequilibrium quench, where the role of time and space are reversed. We include effective range corrections in the EFT and show that they dominate the dynamics near scattering resonances in the presence of deep bound states. Finally, we show how the long-range nature of the Rydberg-Rydberg interactions induces strong effective N-body interactions between Rydberg polaritons. These results pave the way towards studying nonperturbative effects in quantum field theories using Rydberg polaritons.We develop an effective field theory (EFT) to describe the few- and many-body propagation of one-dimensional Rydberg polaritons.
