Knotted nature

The final publication of my PhD was accepted into Nature Physics and was also selected as the front cover article. My contribution to this publication was in setting up and running the experiment alongside optimising the experiment parameters and processing the data.

In a nutshell, the result of the paper is the first demonstration of isolated knotted optical vortices in a laser beam. This means that we were able to engineer the light in the beam such that it circulated in the pattern of a knot.

The experiment’s success derived from combining two very separate domains: knot theory and holography.
