Cooperative Atom-Light Interaction in a Blockaded Rydberg Ensemble (2010)
Journal Article
Pritchard, J., Maxwell, D., Gauguet, A., Weatherill, K., Jones, M., & Adams, C. (2010). Cooperative Atom-Light Interaction in a Blockaded Rydberg Ensemble. Physical Review Letters, 105(19), Article 193603. https://doi.org/10.1103/physrevlett.105.193603

By coupling a probe transition to a Rydberg state using electromagnetically induced transparency (EIT) we map the strong dipole-dipole interactions onto an optical field. We characterize the resulting cooperative optical nonlinearity as a function of... Read More about Cooperative Atom-Light Interaction in a Blockaded Rydberg Ensemble.

Design and characterization of a field-switchable nanomagnetic atom mirror (2010)
Journal Article
Hayward, T., West, A., Weatherill, K., Curran, P., Fry, P., Fundi, P., …Allwood, D. (2010). Design and characterization of a field-switchable nanomagnetic atom mirror. Journal of Applied Physics, 108(4), https://doi.org/10.1063/1.3466995

We present a design for a switchable nanomagnetic atom mirror formed by an array of 180° domain walls confined within Ni80Fe20 planar nanowires. A simple analytical model is developed which allows the magnetic field produced by the domain wall array...

Enhanced electric field sensitivity of rf-dressed Rydberg dark states (2010)
Journal Article
Bason, M., Tanasittikosol, M., Sargsyan, A., Mohapatra, A., Sarkisyan, D., Potvliege, R., & Adams, C. (2010). Enhanced electric field sensitivity of rf-dressed Rydberg dark states. New Journal of Physics, 12, Article 065015. https://doi.org/10.1088/1367-2630/12/6/065015

Optical detection of Rydberg states using electromagnetically induced transparency (EIT) enables continuous measurement of electric fields in a confined geometry. In this paper, we demonstrate the formation of radio frequency (rf)-dressed EIT resonan... Read More about Enhanced electric field sensitivity of rf-dressed Rydberg dark states.

Optical control of Faraday rotation in hot Rb vapor (2010)
Journal Article
Siddons, P., Adams, C., & Hughes, I. (2010). Optical control of Faraday rotation in hot Rb vapor. Physical Review A, 81(4), Article 043838. https://doi.org/10.1103/physreva.81.043838

We demonstrate controlled polarization rotation of an optical field conditional on the presence of a second field. Induced rotations of greater than π/2 rad are seen with a transmission of 95%, corresponding to a ratio of phase shift to absorption of...
