Resonant energy transfer within the Stark manifold

Resonant energy exchange among ultracold Rydberg atoms has been used in quantum computing, quantum simulation, and studies of dynamics in closed quantum systems. Prior studies of dipole-dipole interaction have focused on systems with few initial and final states. We have observed interactions among atoms excited to states within the Stark manifold. The harmonic nature and large number of states in the manifold allow for rich dynamics in this energy exchange process.
