Superfluid Turbulence Cascades in a Dilute Atomic Film

This Earmarked Scholarship project is aligned with a recently awarded Category 1 research grant. It offers you the opportunity to work with leading researchers and contribute to large projects of national significance.

Uniformly trapped Bose-Einstein condensate (BEC) superfluids have recently emerged as the premier system for the experimental study of two-dimensional quantum turbulence and point vortices. This PhD project aims to answer open questions in turbulence by stirring many vortices into a superfluid Bose-Einstein condensate. This will be accomplished through technical innovations on the UQ BEC apparatus enabling the trapping and manipulation of larger superfluids. The project seeks to determine how an effective viscosity can be experimentally realised in a superfluid through vortex shedding, how vortex dynamics redistribute energy across broad length scales in superfluids, and how superfluid turbulence can arise from classical fluid instabilities. The outcomes of this project will elucidate the links between quantum and classical fluids, and provide unambiguous tests of theoretical models in real-world systems. These results will be beneficial to the understanding of the physics of quantum superfluids, and will inform the engineering of quantum-enhanced devices that utilise trapped superfluid media for precision sensing.

This experimental project will allow for the development of diverse and transferable skills, including electronic and optical design, experimental system design and implementation, software design, and data analysis. This project will also allow for attendance of related international workshops and conferences.  There will also be the opportunity to interact with other projects within the ARC Centre of Excellence for Engineered Quantum Systems (EQUS), as well as the theoretical quantum atom optics group at the University of Queensland.

Students will enrol through the School of Mathematics and Physics.

Preferred educational background

Applications will be judged on a competitive basis taking into account the applicant's previous academic record, publication record, honours and awards, and employment history.

A working knowledge of quantum optics and condensed matter would be of benefit to someone working on this project.

The applicant will demonstrate academic achievement in the field(s) of physics/optics or closely related fields and the potential for scholastic success.

Previous laboratory experience in a ultracold atoms lab and/or publications are highly desirable.

*The successful candidate must commence by Research Quarter 4, 2021. You should apply at least 3 months prior to the research quarter commencement date. International applicants may need to apply much earlier for visa reasons.
