Turbulent cascades in superfluid Flatland (2020-2024)
Abstract
This project aims to answer open questions in turbulence by stirring many tiny whirlpools (vortices) into a superfluid Bose-Einstein condensate. It seeks to determine how vortex dynamics redistribute energy across broad length scales in superfluids, how turbulence arises from instabilities, and how turbulence redistributes energy in multicomponent superfluids. 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.
