16:15 - 17:15 Tuesday 24 May 2022 Video: https://us02web.zoom.us/j/83616069325 Designing non-trivial light distributions, and controlling them during propagation, is of interest for modern optical technologies and
particle/atom trapping. In this presentation I will show how light carrying orbital angular momentum (OAM) can be used to generate optical solitons carrying angular momentum as they propagate, or rotating Turing patterns inside an optical cavity. I will show how the intensity and phase structure of the light can control the number of solitons produced and the rotation speed of the patterns, and how adding polarization structure can lead to even better control. Finally I will show what happens when we move from hot gases to ultracold atomic gases by considering the propagation of far-detuned structured optical fields through Bose Einstein Condensates (BECs).
