FOAM News

We were delighted to attend the 6th International Conference on Optical Angular Momentum (ICOAM22), held on the 12th-17th June 2022 at Tampere University in Finland. Several members of the FOAM group participated:

    • Alison: “Structuring light for controlled propagation of optical and atomic solitons” (talk)
    • Rob: “How to knot microwaves” (talk)
    • Grant: “Propagation of coupled atom-light solitons carrying angular momentum in a Bose-Einstein Condensate” (poster)

New pre-print from the group:

G. Henderson, G. R. M. Robb, G.-L. Oppo, and A. M. Yao, “Control of light-atom solitons and atomic transport by optical vortex beams propagating through a Bose-Einstein Condensate” arXiv:2203.11640.

New paper by Alison and collaborators:

Huge congratulations to FOAM member Rob Cameron who has been awarded a prestigious 5 year Royal Society University Research Fellowship to investigate molecular chirality.

Welcome to 3rd year student Emmanouil Alexakis who was awarded an EPSRC Vacation Bursary to work in the FOAM group over summer.

We had a great time at ICOAM19 presenting our invited talks on “Novel ‘standing waves’ and their applications” and “Control of Spatially Rotating Solutions in a Kerr Cavity” and our poster on “Designing fully-structured light for chiroptical interactions”.

Congratulations to FOAM member Christopher Gibson who successfully defended his thesis in May with external examiner Assoc. Prof. Fabio Biancalana and internal examiner Dr. Aidan Arnold.
