"Dipole-Dipole Interactions Among Ultracold Rydberg Atoms".
For microsecond timescales, the dipole-dipole interaction is the dominant mechanism for energy exchange among atoms in an ultracold gas of highly excited neutral atoms, or Rydberg atoms. By applying a dc electric field it is possible to tune these energy exchange processes into resonance via the Stark effect. I will explore some of the interesting dynamics the can result from these field tuned resonant interactions. Recent experiments will also be discussed, such as the direct imaging of the dipole-dipole interaction using a spatially sensitive ion detector, as well as possible interference in the resonant energy exchange process when atoms are prepared in coherent superposition states.
