SUMMARY:Microwave Control of Rydberg-Rydberg Interactions\, R. G. Herb
  Condensed Matter Seminar\, Deniz Kurdak\, University of Maryland
DESCRIPTION:Experimental control over the strength and angular depende
 nce of interactions between atoms is a key capability for advancing qu
 antum technologies. Here\, we use microwave dressing to manipulate Ryd
 berg-Rydberg interactions in an atomic ensemble. By coupling opposite 
 parity Rydberg states\, we create eigenstates with first-order dipole-
 dipole interactions. We study the modification of the interactions by 
 measuring the statistics of the light retrieved from the ensemble. Fur
 thermore\, we discuss the prospects for the nullification of the inter
 actions and the generation of bound states. These more ambitious inter
 action engineering proposals require precise control over the polariza
 tion of the microwave fields\, which is a challenge for many atomic ph
 ysics experiments. We develop spectroscopic techniques to measure the 
 polarization of microwave fields and utilize multiple sources with ind
 ependent phase and amplitude control to generate arbitrary microwave p
 olarizations.
