Superfluid helium: a probe into the Universe. (2025-2029)

This project aims to develop advanced photonic circuits and microscopy techniques to probe superfluid helium¿the only quantum liquid, characterised by flow without dissipation and quantized vortices. Leveraging these unique characteristics, the devices developed in this project will provide access within a compact laboratory setting to extreme regimes of nonlinear flow, inaccessible even in the world¿TM)s largest wavetanks, and be applied to tackle some of the biggest problems in physics, such as the nature of turbulence and the search for dark matter. This project¿TM)s outcomes will advance Australia¿TM)s leadership in quantum science and precision measurement, fields expected to drive significant economic growth in the coming decades.
