Rydberg interactions modify the transmission of a light field through a cold atomic gas under conditions of electromagnetically induced transparency (EIT).
In this work, we develop a theory for the nonlinear, nonlocal optical response in a such a medium, without employing the adiabatic elimination of the intermediate state. We find an enhancement of this response in the vicinity of the single-photon resonance due to resonant Rydberg dressing of the atoms. Simulations show that this enhancement can be observed experimentally in the transmission of the EIT probe beam.
