Piezoelectrically actuated time-averaged atomic microtraps (2012)
Journal Article
West, A., Wade, C., Weatherill, K., & Hughes, I. (2012). Piezoelectrically actuated time-averaged atomic microtraps. Applied Physics Letters, 101(2), Article 023115. https://doi.org/10.1063/1.4736580

We present a scheme for creating tight and adiabatic time-averaged atom-traps through the piezoelectric actuation of nanomagnetic structures. We show that potentials formed by the circular translation of magnetic structures have several advantages ov... Read More about Piezoelectrically actuated time-averaged atomic microtraps.

Optical preparation and measurement of atomic coherence at gigahertz bandwidth (2012)
Journal Article
Siddons, P., Adams, C., & Hughes, I. (2012). Optical preparation and measurement of atomic coherence at gigahertz bandwidth. Journal of Physics B: Atomic, Molecular and Optical Physics, 45(12), https://doi.org/10.1088/0953-4075/45/12/124009

We detail a method for the preparation of atomic coherence in a high-density atomic vapour of 87Rb, utilizing a coherent preparation scheme of off-resonant gigahertz bandwidth pulses. The scheme is found to be faster and more effective than technique... Read More about Optical preparation and measurement of atomic coherence at gigahertz bandwidth.

Cooperative Lamb Shift in an Atomic Vapor Layer of Nanometer Thickness (2012)
Journal Article
Keaveney, J., Sargsyan, A., Krohn, U., Hughes, I., Sarkisyan, D., & Adams, C. (2012). Cooperative Lamb Shift in an Atomic Vapor Layer of Nanometer Thickness. Physical Review Letters, 108(17), Article 173601. https://doi.org/10.1103/physrevlett.108.173601

We present an experimental measurement of the cooperative Lamb shift and the Lorentz shift using a nanothickness atomic vapor layer with tunable thickness and atomic density. The cooperative Lamb shift arises due to the exchange of virtual photons be... Read More about Cooperative Lamb Shift in an Atomic Vapor Layer of Nanometer Thickness.

Measuring the Stokes parameters for light transmitted by a high-density rubidium vapour in large magnetic fields (2012)
Journal Article
Weller, L., Dalton, T., Siddons, P., Adams, C., & Hughes, I. (2012). Measuring the Stokes parameters for light transmitted by a high-density rubidium vapour in large magnetic fields. Journal of Physics B: Atomic, Molecular and Optical Physics, 45(5), Article 055001. https://doi.org/10.1088/0953-4075/45/5/055001

Here we report on measurements of the absolute absorption and dispersion of light in a dense rubidium vapour on the D2 line in the weak-probe regime with an applied magnetic field. A model for the electric susceptibility of the vapour is presented wh...

A simple model for calculating magnetic nanowire domain wall fringing fields (2012)
Journal Article
West, A., Hayward, T., Weatherill, K., Schrefl, T., Allwood, D., & Hughes, I. (2012). A simple model for calculating magnetic nanowire domain wall fringing fields. Journal of Physics D: Applied Physics, 45(9), Article 095002. https://doi.org/10.1088/0022-3727/45/9/095002

We present a new approach to calculating magnetic fringing fields from head-to-head type domain walls (DWs) in planar magnetic nanowires. In contrast to calculations based on micromagnetically simulated structures the descriptions of the fields are f...
