contemporary atomic physics were first demonstrated in hot vapours. Alkali-metal atomic …

[HTML][HTML] ElecSus: A program to calculate the electric susceptibility of an atomic ensemble

MA Zentile, J Keaveney, L Weller, DJ Whiting… - Computer Physics …, 2015 - Elsevier
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 …

Collective Lamb shift of a nanoscale atomic vapor layer within a sapphire cavity

T Peyrot, YRP Sortais, A Browaeys, A Sargsyan… - Physical Review Letters, 2018 - APS
We measure the near-resonant transmission of light through a dense medium of potassium

Maximum refractive index of an atomic medium

F Andreoli, MJ Gullans, AA High, A Browaeys… - Physical Review X, 2021 - APS
It is interesting to observe that all optical materials with a positive refractive index have a
value of index that is of order unity. Surprisingly, though, a deep understanding of the …

The hyperfine Paschen–Back Faraday effect

MA Zentile, R Andrews, L Weller… - Journal of Physics B …, 2014 - iopscience.iop.org
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 …

Circular dichroism of magnetically induced transitions for D2 lines of alkali atoms

Optical transmission of an atomic vapor in the mesoscopic regime

T Peyrot, YRP Sortais, JJ Greffet, A Browaeys… - Physical Review Letters, 2019 - APS
By measuring the transmission of near-resonant light through an atomic vapor confined in a
nanocell we demonstrate a mesoscopic optical response arising from the nonlocality …

Optical Response of Gas-Phase Atoms at Less than from a Dielectric Surface

KA Whittaker, J Keaveney, IG Hughes, A Sargsyan… - Physical Review Letters, 2014 - APS
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 …
