ElecSus: A program to calculate the electric susceptibility of an atomic ensemble (2014)
Journal Article
Zentile, M., Keaveney, J., Weller, L., Whiting, D., Adams, C., & Hughes, I. (2015). ElecSus: A program to calculate the electric susceptibility of an atomic ensemble. Computer Physics Communications, 189, 162-174. https://doi.org/10.1016/j.cpc.2014.11.023

We present a computer program and underlying model to calculate the electric susceptibility of a gas, which is essential to predict its absorptive and dispersive properties. Our program focuses on alkali-metal vapours where we use a matrix representa... Read More about ElecSus: A program to calculate the electric susceptibility of an atomic ensemble.

Optical Response of Gas-Phase Atoms at Less than λ/80 from a Dielectric Surface (2014)
Journal Article
Whittaker, K., Keaveney, J., Hughes, I., Sargsyan, A., Sarkisyan, D., & Adams, C. (2014). Optical Response of Gas-Phase Atoms at Less than λ/80 from a Dielectric Surface. Physical Review Letters, 112, Article 253201. https://doi.org/10.1103/physrevlett.112.253201

We present experimental observations of atom-light interactions within tens of nanometers (down to 11 nm) of a sapphire surface. Using photon counting we detect the fluorescence from of order one thousand Rb or Cs atoms, confined in a vapor with thic...

The hyperfine Paschen-Back Faraday effect (2014)
Journal Article
Zentile, M. A., Andrews, R., Weller, L., Knappe, S., Adams, C. S., & Hughes, I. G. (2014). The hyperfine Paschen-Back Faraday effect. Journal of Physics B: Atomic, Molecular and Optical Physics, 47(7), Article 075005. https://doi.org/10.1088/0953-4075/47/7/075005

We investigate experimentally and theoretically the Faraday effect in an atomic medium in the hyperfine Paschen–Back regime, where the Zeeman interaction is larger than the hyperfine splitting. We use a small permanent magnet and a micro-fabricated v... Read More about The hyperfine Paschen-Back Faraday effect.
