Title: Dipolar QED (dQED): an alternative paradigm for quantum optics.

Time and place: Thursday January 7, 11:15-12:00, 1520-732

Abstract:

In the strong coupling regime of cavity QED, a single photon modifies the optical response of the atom-cavity system to subsequent photons. An analogous effect can occur in atomic ensembles without the need of a cavity, if the atoms interact strongly. For example a single photon stored as a Rydberg excitation can switch the optical response of the ensemble to subsequent photons. In this talk we review some applications of this dipolar QED effect in both the quantum and classical regimes.

Tea and coffee will be available from 11:00.
