Throughout nature, complex systems are found to exhibit remarkably similar scale-invariant properties that are exceedingly difficult to explain from microscopic principles. Recently we discovered self-organisation and the emergence of scale-invariant behaviour in systems of ultracold atoms driven to Rydberg states by laser fields, providing one of the first clean experimental realizations of "self-organised criticality" (SOC). In this project we will develop the technology for controlling ultracold Rydberg atoms even further for exploring complex quantum dynamics in currently poorly-understood regimes. This will enable the first comprehensive determination of the universal properties of self-organised critical systems which can be directly linked to theoretical models derived from the underlying microscopic physics. We will also address long standing questions, such as how do quantum fluctuations modify the non-equilibrium universal properties. Finally, we will explore how self-organising dynamics might be harnessed to engineer complex quantum states and process quantum information.
This highly collaborative 3 year funded project is embedded in the Giant Interactions in Rydberg Systems network [www.giryd.de] and involves exceptionally strong collaborations with the theory groups. The selected candidate will also be part of the International Graduate School Quantum Science and Nanomaterials [qmat.unistra.fr] and the Doctoral College ED182
Candidates are expected to have a strong background in atomic physics and quantum mechanics. Experimental experience will be highly beneficial. Interested candidates should contact Shannon Whitlock (
