Microwave control of the interaction between two optical photons

D. Maxwell, D. J. Szwer, D. P. Barato +5

A microwave field is used to control the interaction between pairs of optical photons stored in highly excited collective states (Rydberg polaritons). We show that strong dipole-di…

Storage and control of optical photons using Rydberg polaritons

D. Maxwell, D. J. Szwer, D. P. Barato +6

We use a microwave field to control the quantum state of optical photons stored in a cold atomic cloud. The photons are stored in highly excited collective states (Rydberg polarito…

Non-linear optics using cold Rydberg atoms

J. D. Pritchard, K. J. Weatherill, C. S. Adams

The implementation of electromagnetically induced transparency (EIT) in a cold Rydberg gas provides an attractive route towards strong photon--photon interactions and fully determi…

Fractional photon-assisted tunnelling of ultra-cold atoms in periodically shaken double-well lattices

Martin Esmann, Jonathan D. Pritchard, Christoph Weiss

Fractional photon-assisted tunnelling is investigated both numerically and analytically in a double-well lattice. While integer photon-assisted tunnelling is a single-particle effe…

Correlated photon emission from multi--atom Rydberg dark states

J. D. Pritchard, C. S. Adams, K. Mølmer

We consider three level atoms driven by two resonant light fields in a ladder scheme where the upper level is a highly excited Rydberg state. We show that the dipole--dipole intera…

Optical non-linearity in a dynamical Rydberg gas

J D Pritchard, A Gauguet, K J Weatherill +1

We use the technique of electro-magnetically induced transparency (EIT) to probe the effect of attractive dipole-dipole interactions in a highly excited Rydberg gas. The transient…
