This project aims to harness the ability to control the fundamental interactions which limit the precision of a diamond quantum sensor, enabling more sensitive magnetometry. Quantum sensors are unveiling new insights into nano-scale phenomena. Single atom defects in diamonds have been at the forefront of this revolution in nano-scale sensor technology. A unique capability, spinning diamond quantum sensors at up to 500,000 rpm, fast enough that quantum properties of the defects are preserved during a cycle has been established. This project will address the long-standing problem of nano-scale solid-materials characterisation using rotationally-enhanced quantum magnetic resonance spectroscopy.Read moreRead less
Measuring critical background in the Australian search for dark matter. This project aims to develop ultra-sensitive detector technology essential for SABRE, a world-wide experiment with detectors in both the Northern and Southern Hemispheres which are operated together to directly detect the dark matter halo of our Milky Way galaxy. Dark matter makes up nearly five times more mass in the universe than everything we can see, yet it has never been detected in the laboratory. SABRE South will be i ....Measuring critical background in the Australian search for dark matter. This project aims to develop ultra-sensitive detector technology essential for SABRE, a world-wide experiment with detectors in both the Northern and Southern Hemispheres which are operated together to directly detect the dark matter halo of our Milky Way galaxy. Dark matter makes up nearly five times more mass in the universe than everything we can see, yet it has never been detected in the laboratory. SABRE South will be installed in the Stawell Underground Physics Laboratory in a goldmine in Victoria, Australia. Dark matter is not the only thing SABRE can detect. The project will measure all possible types of naturally occurring radiation, from space, the surrounding rock, and the detectors themselves, that can blind SABRE to dark matter.Read moreRead less
Australia’s first direct-detection dark matter search, at Stawell Gold Mine. This project aims to develop an underground integrated laboratory at Stawell Gold Mine in Victoria to host the Southern Hemisphere's first-ever direct-detection dark matter experiment. Following the Higgs boson discovery, the direct detection of dark matter is seen as the next major challenge for particle physics.

This project aims to develop an underground integrated laboratory at Stawell Gold Mine in Victoria to host the Southern Hemisphere's first-ever direct-detection dark matter experiment. Following the Higgs boson discovery, the direct detection of dark matter is seen as the next major challenge for particle physics. This project sees Australian physicists team up with local and international partners in research and industry to join the search for dark matter. This Australian experiment aims to help to confirm or deny current results from Northern Hemisphere experiments. As the mine nears the end of its working life as a gold mine, this project is expected to benefit the local economy and provide opportunities for education and outreach.Read moreRead less

Summary
Viewing Chemistry through Diamond: Quantum Sensors for Realtime in situ NMR. This project aims to develop a new analytical method and integrated platform technology for time dependent, in situ monitoring of chemical reactions. The proposed research will capitalise on recent developments made in the field of diamond-based quantum sensing to enable the resolution of chemical species and their concentrations within the timescales associated with many important reaction systems. This project thus ex ....Viewing Chemistry through Diamond: Quantum Sensors for Realtime in situ NMR. This project aims to develop a new analytical method and integrated platform technology for time dependent, in situ monitoring of chemical reactions. The proposed research will capitalise on recent developments made in the field of diamond-based quantum sensing to enable the resolution of chemical species and their concentrations within the timescales associated with many important reaction systems. This project thus expects to generate knowledge in both quantum metrology and physical chemistry. Moreover, the realisation of this technology has significant potential to improve the design and manufacture of important advanced materials, ranging from clean energy production and storage, to pharmaceutical development and drug discovery.Read moreRead less
Building time crystals with ultracold atoms. This project aims to create a new exotic form of quantum matter in which a many-body system of ultracold atoms bouncing on a vibrating mirror spontaneously self-organises its motion with a period tens of times longer than the driving period of the mirror. Such ‘time crystals’ are predicted to be robust against external perturbations and to persist for very long times. The project expects to generate new knowledge on exotic non-equilibrium crystalline ....Building time crystals with ultracold atoms. This project aims to create a new exotic form of quantum matter in which a many-body system of ultracold atoms bouncing on a vibrating mirror spontaneously self-organises its motion with a period tens of times longer than the driving period of the mirror. Such ‘time crystals’ are predicted to be robust against external perturbations and to persist for very long times. The project expects to generate new knowledge on exotic non-equilibrium crystalline phenomena in the time domain, such as many-body localisation with temporal disorder, which has counter-intuitive characteristics such as absence of thermalisation and vanishing direct current transport. Time crystals could provide significant benefits for the storage and transfer of quantum information, and this, and other outcomes may ultimately lead to commercial products.Read moreRead less
Transport and impurity dynamics in a unitary Fermi gas. This project aims to generate new understandings of transport and the behaviour of impurities in a gas of strongly-interacting atoms cooled to nanoKelvin temperatures. By measuring the response of a unitary Fermi gas to disturbances with well-defined momenta and energies, we will map the elementary excitations in both the superfluid and normal fluid phases. From this, the parameters that define how particles and impurities travel through th ....Transport and impurity dynamics in a unitary Fermi gas. This project aims to generate new understandings of transport and the behaviour of impurities in a gas of strongly-interacting atoms cooled to nanoKelvin temperatures. By measuring the response of a unitary Fermi gas to disturbances with well-defined momenta and energies, we will map the elementary excitations in both the superfluid and normal fluid phases. From this, the parameters that define how particles and impurities travel through the system can be determined. Our study will reveal whether the unitary Fermi gas approaches a conjectured quantum limit for perfect fluidity, examine how the properties of the gas depend on impurity concentration and establish new benchmarks for theories of strongly-correlated quantum matter.Read moreRead less
A Stress-relax Model for Stellar Flares. This project aims to improve our ability to predict solar and stellar flares by developing a theoretical model for the build-up and release of magnetic stress in stellar atmospheres. Solar flares are the most energetic events in the solar system, and together with associated coronal mass ejections can create hazardous conditions in our local space environment. Stellar flares are thousands of times more energetic and produce dangerous space weather for exo ....A Stress-relax Model for Stellar Flares. This project aims to improve our ability to predict solar and stellar flares by developing a theoretical model for the build-up and release of magnetic stress in stellar atmospheres. Solar flares are the most energetic events in the solar system, and together with associated coronal mass ejections can create hazardous conditions in our local space environment. Stellar flares are thousands of times more energetic and produce dangerous space weather for exoplanets orbiting flare stars. Expected outcomes include insight into the flare mechanism, and new approaches to flare prediction. The major potential benefit is improved solar and stellar space weather forecasting to protect human safety and infrastructure.Read moreRead less
