The Australian alumina and aluminium industries contribute over $11 billion export income annually. All refineries, except one, operate in rural areas and are the main economic drivers in these regions. In order to maintain the industry's commitment to reduce the environmental impact of its processes and remain economically sustainable, innovative technologies are required to monitor mercury emissions. The aim of this project is to develop robust sensors, for online monitoring of mercury vapours, that operate under challenging industrial environments. This project will also provide excellent training for young researchers in established international industrial research groups, thereby meeting skill shortages in the Australian resource sector.Read moreRead less

Summary
Calming the Superfluid Storm: Taming Turbulence in Superfluid Devices. Turbulence, the chaotic flow of fluids, occurs in the vast majority of fluid flows in nature. This project aims to develop a new understanding of turbulence in superfluids, a class of quantum fluids which can flow without friction. The significance is that aspects of turbulence are universal, so that discoveries in superfluid turbulence will provide fundamental insights into all forms of turbulence. The expected outcomes are ....Calming the Superfluid Storm: Taming Turbulence in Superfluid Devices. Turbulence, the chaotic flow of fluids, occurs in the vast majority of fluid flows in nature. This project aims to develop a new understanding of turbulence in superfluids, a class of quantum fluids which can flow without friction. The significance is that aspects of turbulence are universal, so that discoveries in superfluid turbulence will provide fundamental insights into all forms of turbulence. The expected outcomes are solutions to two outstanding questions – what are the universal laws of turbulent flow for superfluids, and what new forms of quantum vortex matter are possible? New insights into turbulence will benefit all applications which rely on its understanding, for example in medicine, aviation, and climate modelling.Read moreRead less
Propagation and properties of solitonic matterwaves in atomic metamaterials. This project aims to develop and investigate solitonic matter waves interacting with crystals of light, known as optical lattices. Using a unique apparatus, the project plans to investigate how solitonic matter waves propagate in their ground and excited states, how those matter waves interact with each other, and how we can manufacture new optical materials to obtain different, and potentially useful, new behaviour.

Using a unique apparatus, the project plans to investigate how solitonic matter waves propagate in their ground and excited states, how those matter waves interact with each other, and how we can manufacture new optical materials to obtain different, and potentially useful, new behaviour. Although the proposed studies are purely fundamental in nature, the project has the potential to affect the field of quantum sensors, where solitonic matter waves are predicted to offer gains over traditional atom sources.Read moreRead less

Summary
Quantum enhancement for ultra-precise atomic sensors. This project will investigate methods for drastically improving the sensitivity of measurement devices derived from atom interferometers. This will enable experimental tests of certain aspects of fundamental physics, as well as practical tools such as ultra-precise geodesy for minerals exploration.
Creating high flux degenerate quantum atomic sources with active feedback. This project aims to deliver a new technique for cooling dilute ultracold gases, which are rapidly transitioning from a fundamental physics platform to a building block for quantum technology. This technique is measurement-based feedback cooling. Unlike the current evaporative methods, feedback cooling neither loses atoms, nor relies on elastic collisions or internal atomic structure.

This project aims to deliver a new technique for cooling dilute ultracold gases, which are rapidly transitioning from a fundamental physics platform to a building block for quantum technology. This technique is measurement-based feedback cooling. Unlike the current evaporative methods, feedback cooling neither loses atoms, nor relies on elastic collisions or internal atomic structure. This opens up the possibility of directly cooling traditionally un-coolable systems. This project will expand the quality and range of available atomic sources, benefitting research into exotic materials, and improving precision sensor applications. Quantum sensors are rapidly reforming our image of what a sensor is and what it can do, offering unprecedented opportunities in sensor fusion, and directly impacting business opportunities in mineral exploration, mapping and navigation.Read moreRead less
