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...

Off-resonance absorption and dispersion in vapours of hot alkali-metal atoms (2009)
Journal Article
Siddons, P., Adams, C., & Hughes, I. (2009). Off-resonance absorption and dispersion in vapours of hot alkali-metal atoms. Journal of Physics B: Atomic, Molecular and Optical Physics, 42(17), Article 175004. https://doi.org/10.1088/0953-4075/42/17/175004

We study the absorptive and dispersive properties of Doppler-broadened atomic media as a function of detuning. Beginning from the exact lineshape calculated for a two-level atom, a series of approximations to the electric susceptibility are made. The...

Bright solitary waves of trapped atomic Bose-Einstein condensates (2009)
Journal Article
Parker, N., Martin, A., Adams, C., & Cornish, S. (2009). Bright solitary waves of trapped atomic Bose-Einstein condensates. Physica D: Nonlinear Phenomena, 238(15), 1456-1461. https://doi.org/10.1016/j.physd.2008.07.001

Motivated by recent experimental observations, we study theoretically multiple bright solitary waves of trapped Bose–Einstein condensates. Through variational and numerical analyses, we determine the threshold for collapse of these states. Under π-ph... Read More about Bright solitary waves of trapped atomic Bose-Einstein condensates.

A gigahertz-bandwidth atomic probe based on the slow-light Faraday effect (2009)
Journal Article
Siddons, P., Bell, N., Cai, Y., Adams, C., & Hughes, I. (2009). A gigahertz-bandwidth atomic probe based on the slow-light Faraday effect. Nature Photonics, 3(4), 225-229. https://doi.org/10.1038/nphoton.2009.27

The ability to probe quantum systems on short timescales is central to the advancement of quantum technology. Here we show that this is possible using an off-resonant dispersive probe. By applying a magnetic field to an atomic vapour the spectra of t... Read More about A gigahertz-bandwidth atomic probe based on the slow-light Faraday effect.

Laser frequency stabilization to excited state transitions using electromagnetically induced transparency in a cascade system (2009)
Journal Article
Abel, R., Mohapatra, A., Bason, M., Pritchard, J., Weatherill, K., Raitzsch, U., & Adams, C. (2009). Laser frequency stabilization to excited state transitions using electromagnetically induced transparency in a cascade system. Applied Physics Letters, 94(7), Article 071107. https://doi.org/10.1063/1.3086305

We demonstrate laser frequency stabilization to excited state transitions using cascade electromagnetically induced transparency. Using a room temperature Rb vapor cell as a reference, we stabilize a first diode laser to the D2 transition and a secon...
