We will contribute to Australia's skill base via the training of the best and brightest postgraduate students. These students will be equipped with the skills to act as original thinkers on general problems in the wider community. Fundamental questions about the nature of our Universe engage the intellectual curiosity of the general public and inspire the next generation of scientists.Read moreRead less
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
Frontiers in particle and astroparticle physics. This project will address fundamental questions about our universe, drawing on new experimental data at the cosmic and energy frontiers: what is the cosmological dark matter; why does the universe contain more matter than antimatter; what new surprises may be revealed? The answers will provide a guide to develop fundamental theories of nature.

Summary
The human nervous system and organs are reliant on precisely controlled transmission of electrical currents through sodium and potassium channels. Their core functions are compromised when currents fail to switch on and off normally. Faulty potassium channels are implicated in diabetes, epilepsy and heart failure. This project re-examines the mechanisms controlling potassium channels, with a view to scientific and therapeutic discrimination between the different classes present in human cells.
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

Imaging in three dimensions beyond the nanoscale. After two decades of research the first wave of applications in nanotechnology and nanobiology is breaking. The economic stakes are high: nanostructured electronics and photonics will be the next epoch after transistors (1947) and the microprocessor (1971), and designer therapies and drugs will be in high demand. Immediately key to further progress in both areas is the ability to characterize structure in three dimensions at and beyond the nanosc ....Imaging in three dimensions beyond the nanoscale.

Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the interg ....Pinpointing the hosts of Fast Radio Bursts with UTMOST-2D. This project proposes to localise a sample of detected ‘fast radio bursts’ to their host galaxies (or local progenitors) for the first time. ‘Fast radio bursts’ are impulsive bursts of radio energy, with characteristics consistent with an origin billions of light-years from Earth. If the source of the bursts can be pinpointed, they would offer a unique tool to study the tenuous, otherwise nearly invisible plasma that permeates the intergalactic medium. They could also be used as cosmic rulers to measure the expansion history of the Universe. To date, no burst has been associated with a host galaxy at a known distance, and some researchers maintain that fast radio bursts originate from more nearby sources, potentially even within our own Galaxy. The project plans to explore this hypothesis.Read moreRead less
