Polaritons, which are superpositions of a photonic and a collective atomic excitation, can interact via dressing to long-range interacting Rydberg states. This opens the possibility for investigating many-body physics with photons as well as strongly correlated states of light. For observing these effects strong interactions or large interaction times are needed. However, the latter is usually limited by the propagation time of the slow light polariton through the medium under conditions of electromagnetically induced transparency (EIT). We show that this limitation can be overcome by generating propagation free photonic excitations, so called stationary light polaritons, and explain how this kind of polaritons can serve to engineer strongly interacting many body systems.
