The origin of (dark) matter. This project aims to discover the origin and nature of dark matter and why the Universe contains more matter than antimatter – two important unresolved problems in particle physics and cosmology. These questions cannot be resolved within the framework of the particle physics Standard Model, and thus provide concrete evidence that new elementary particle physics remains to be uncovered. This project aims to explore the origin of dark matter, new mechanisms for creatin ....The origin of (dark) matter. This project aims to discover the origin and nature of dark matter and why the Universe contains more matter than antimatter – two important unresolved problems in particle physics and cosmology. These questions cannot be resolved within the framework of the particle physics Standard Model, and thus provide concrete evidence that new elementary particle physics remains to be uncovered. This project aims to explore the origin of dark matter, new mechanisms for creating a matter-antimatter asymmetry, and the possibility that dark and ordinary matter share a common origin. This project could address humanity's deep need to understand the nature of the universe and our origins.Read moreRead less
Implementing large-scale solid-state quantum computation. The goal of quantum computing research is to harness the properties of quantum mechanics to build computers that are exponentially more powerful than the computers of today. Along the way, many spin-off technologies for conventional computing and nanotechnology are expected. Realising the quantum computing dream is a daunting experimental challenge requiring both theoretical assurance that it is possible in principle, and theoretical guid ....Implementing large-scale solid-state quantum computation. The goal of quantum computing research is to harness the properties of quantum mechanics to build computers that are exponentially more powerful than the computers of today. Along the way, many spin-off technologies for conventional computing and nanotechnology are expected. Realising the quantum computing dream is a daunting experimental challenge requiring both theoretical assurance that it is possible in principle, and theoretical guidance as to the best method. We seek to provide this theoretical support for solid-state systems, and broaden the range of problems that such systems are demonstrably suited to tackle.Read moreRead less
Atom Location by Channelling Enhanced Microanalysis using Inner-shell Electron Energy Loss Spectroscopy. The technique of Atom Location by Channelling Enhanced Microanalysis (ALCHEMI) has been explored extensively using Electron Energy Dispersive X-ray (EDX) measurements by many authors. The extension of this method to Electron Energy Loss Spectroscopy (EELS) is difficult due to the more complicated formulation of inner-shell ionization required under such experimental conditions.

The technique of Atom Location by Channelling Enhanced Microanalysis (ALCHEMI) has been explored extensively using Electron Energy Dispersive X-ray (EDX) measurements by many authors. The extension of this method to Electron Energy Loss Spectroscopy (EELS) is difficult due to the more complicated formulation of inner-shell ionization required under such experimental conditions. Issues such as the "delocalization" of the ionization interaction and the significance of channelling of the scattered electron need to be addressed so that this method may be generally applicable. It is the aim of this project to extend this commonly used method to the topical field of EELS.Read moreRead less
The phase and inverse scattering problem for electrons multiply scattered by non-periodic solids. Theoretical methods for the inversion of multiple scattering of electrons in non-periodic solids will be obtained. This will vastly extend the range of utility of atomic resolution electron microscopy and electron tomography, where single scattering conditions are usually assumed. We will further develop our recent novel solutions to the phase problem from images and diffraction patterns (needed as ....The phase and inverse scattering problem for electrons multiply scattered by non-periodic solids. Theoretical methods for the inversion of multiple scattering of electrons in non-periodic solids will be obtained. This will vastly extend the range of utility of atomic resolution electron microscopy and electron tomography, where single scattering conditions are usually assumed. We will further develop our recent novel solutions to the phase problem from images and diffraction patterns (needed as a prelude to the inversion) that are robust in the presence of discontinuities in the phase (such as vortices). These phase retrieval methods will be useful not only for problems in electron optics but also in visible, x-ray, neutron and atom optics.Read moreRead less

This project aims to capitalise on the dawn of the era of gravitational wave astronomy by studying the radio afterglows that result from gravitational wave merger events in minute detail. By comparing ultra-high resolution images to sophisticated computational models, we anticipate recovering information about the merger events that cannot be obtained from the gravitational wave data alone. In doing so, we expect new insights into not just of the extreme and unique physics in the aftermath of a violent neutron star merger, but also about the fundamental nature of the Universe, namely the speed at which it is expanding. This knowledge will provide significant benefits to astronomers studying the Universe at all wavelengths.Read moreRead less

This project expects to localise 100s of bursts using novel infrastructure deployed on Australia's largest radio telescopes. Expected outcomes include an understanding of the processes that shape both the large-scale structures of the Universe, and the extreme conditions that exist at the sites of Fast Radio Bursts. This should provide significant benefits to our fundamental knowledge of the Universe, inspire students into careers in science, technology, engineering and mathematics, and develop signal processing techniques of application to both the Square Kilometre Array and industry.Read moreRead less
