Title: Accessing Rydberg-dressed interactions using many-body Ramsey dynamics
Abstract: We demonstrate that Ramsey spectroscopy can be used to observe Rydberg-dressed
interactions in a many-body system. Our scheme operates comfortably within experimentally
measured lifetimes, and accesses a regime where quantum superpositions are crucial. We
build a spin-1/2 from one level that is Rydberg-dressed and another that is not. These
levels may be hyperfine or long-lived electronic states. An Ising spin model governs the
Ramsey dynamics, for which we derive an exact solution. Due to the structure of Rydberg
interactions, the dynamics differs significantly from that in other spin systems. As one
example, spin echo can increase the rate at which coherence decays.
Location: B-106 @ Center for Astrophysics (60 Garden Street)
Directions: After entering the lobby of the CfA, turn right to enter the hallway of the B
building. In the hallway, turn right again, B-106 will be at the end of the hallway on the
left side.
