Self-organized magnetic and droplet states for quantum technologies

The project will investigate self-organized phases in cold atoms with light-mediated coupling. We are looking at laser cooled thermal atoms or quantum degenerate gases driven by a detuned laser beam with feedback from a single mirror or a cavity leading to the spontaneous emergence of intriguing spatial structures, from localized droplets to periodic structures like stripes and hexagons. Depending on the interest of the student, it can have a theoretical or experimental focus and would be either supervised by Prof Ackemann or Dr Robb as lead supervisor.

For more details, please contact Prof Thorsten Ackemann - thorsten.ackemann@strath.ac.uk.
