I am a PhD Student in the Atomic and Molecular Physics group at Durham University. My project is funded by the Max Planck Institute for the Science of Light and the work is a collaborative effort in the field of atomic physics and nano-optics.

Working with thermal vapour of Rubidium, we seek to exploit the relative simplicity (compared to cold atom experiments) and see quantum phenomena. We construct our own nano-scale vapour cells that allow us to study Rubidium atoms in extremely confined geometries with a goal to create a single addressable atom in thermal vapour. We implement numerous detection methods including transmission spectroscopy, fluorescence spectroscopy, total internal reflection fluorescence, and confocal microscopy. All of which allow us to be sensitive to the single photon and single atom level whilst also providing the spatial resolving power required to probe our sub-micron scale vapour cell structures.

Ultimately, we seek to control the presence of individual atoms on the sub-wavelength scale and provide a switchable single photon source. Our work shows utility in quantum optics, atom-light interactions, non-linear optics, and quantum information processing.

my cell is so very thin

I can see atoms"
