Light storage and control of photon-photon interactions in a cold Rydberg gas [PDF]

, 2013
The effect of strong interatomic interactions on an optical field stored in Rydberg states of a cold atomic gas is investigated. Due to their large dipole moments Rydberg atoms interact very strongly with each other.
