Engineering superfluid transport with dissipation

The emerging field of atomtronics uses superfluid quantum gases to build functional circuits inspired by traditional electronics. Unlike electronic systems, however, quantum gases exhibit coherence and can flow without viscosity, properties that enable distinctive transport phenomena and new device concepts. As atomtronics approaches a transition from fundamental exploration to practical devices, progress is increasingly limited by a lack of understanding of far‑from‑equilibrium superfluid transport. Addressing this challenge is essential for the development of high‑precision quantum sensors and simulators based on superfluids.

The aim of this theoretical physics PhD project is to design and model an atomtronic circuit element exhibiting negative differential conductance (NDC) arising in the far‑from‑equilibrium dynamics controlled by patterned dissipation and controlled atomic losses. Building on this, you will demonstrate how such behaviour can be harnessed to realise a diode, transistor, or another novel atomtronic circuit elements. 

The research environment for this project at UQ is world-class, with quantum physics identified as a strategic strength of the School of Mathematics and Physics. The applicant will benefit from a vibrant HDR community, regular seminars, and opportunities for national and international collaboration. The project aligns strongly with institutional and national priorities, including Queensland’s Quantum and Advanced Technologies Strategy, ensuring strategic relevance and high-impact outcomes.

The project will be hosted by the quantum gas theory group in the School of Mathematics in Physics, made up of three academic staff and a number of PhD students and postdoctoral fellows.  We will work closely with researchers at the University of Oxford, and the UQ Bose-Einstein condensation experimental group.

This project is supported by the Research project scholarship.
