Voices of Regional Australia: The linguistic patterning of local attachment. This project aims to investigate language and social dynamics among regional Australians, who, despite representing one third of the population, have been often neglected in the research to date. The project expects to generate new knowledge around regional attachment and the impact that has on speech patterns, adapting for the first time recently developed international metrics to the Australian context. Expected outco ....Voices of Regional Australia: The linguistic patterning of local attachment. This project aims to investigate language and social dynamics among regional Australians, who, despite representing one third of the population, have been often neglected in the research to date. The project expects to generate new knowledge around regional attachment and the impact that has on speech patterns, adapting for the first time recently developed international metrics to the Australian context. Expected outcomes include a better understanding of models of language change across urban and rural areas, and a novel dataset recording the stories of regional Australians, and in particular, their experiences facing bushfire. This should provide significant benefits as a record of life, language and community in regional Australia.Read moreRead less
Superdeformed nuclei and their decay: challenging nuclear models and probing quantum tunnelling. Nuclear superdeformation, where the atomic nucleus adopts an elongated, ellipsoidal shape and can undergo rapid rotation, offers a fascinating opportunity to study quantum mechanical effects in a system where single-particle and collective regimes overlap. The superdeformed shape itself is a spectacular example of collective motion in a mesoscopic system, while the rapid change to a sperhical shape ....Superdeformed nuclei and their decay: challenging nuclear models and probing quantum tunnelling. Nuclear superdeformation, where the atomic nucleus adopts an elongated, ellipsoidal shape and can undergo rapid rotation, offers a fascinating opportunity to study quantum mechanical effects in a system where single-particle and collective regimes overlap. The superdeformed shape itself is a spectacular example of collective motion in a mesoscopic system, while the rapid change to a sperhical shape is an excellent example of quantum-assisted tunnelling. The results of this project will shed light on this important process and provide a stringent test of our understanding of the nucleus.Read moreRead less
Languages of Barrier Islands, Sumatra: Description, History and Typology. This project aims to investigate endangered languages of the Asia-Pacific via four undocumented languages in the Barrier Islands, Indonesia. New knowledge will be generated into the languages, cultures and societies of the region on an unprecedented scale, and be made freely available to the public. New data will uncover past migration patterns in Southeast Asia, advance language theory (such as linguistic typology and lan ....Languages of Barrier Islands, Sumatra: Description, History and Typology. This project aims to investigate endangered languages of the Asia-Pacific via four undocumented languages in the Barrier Islands, Indonesia. New knowledge will be generated into the languages, cultures and societies of the region on an unprecedented scale, and be made freely available to the public. New data will uncover past migration patterns in Southeast Asia, advance language theory (such as linguistic typology and language change), and support the computational modelling of Austronesian for future language technologies. Connections with Indonesian institutions will strengthen Australia’s regional engagement, and support language revitalisation and maintenance among minority communities for the preservation of their culture and history.Read moreRead less
Isomers as Probes of Nuclear Structure and Sources of Energetic Photons. The aim is to study exotic long-lived states in nuclei using accelerator facilities in Australia and overseas. This involves the development of sensitive instrumentation and will lead to a new understanding of how such states are formed, of how they may be used to identify the structure of exotic nuclei, and on the limits of stability of nuclei in general. Isomers represent a special form of nuclear matter and they play a r ....Isomers as Probes of Nuclear Structure and Sources of Energetic Photons. The aim is to study exotic long-lived states in nuclei using accelerator facilities in Australia and overseas. This involves the development of sensitive instrumentation and will lead to a new understanding of how such states are formed, of how they may be used to identify the structure of exotic nuclei, and on the limits of stability of nuclei in general. Isomers represent a special form of nuclear matter and they play a role in the formation of the elements in stellar nucleosynthesis. Stimulated isomer decay may ultimately lead to new forms of energy storage and gamma-ray lasers.Read moreRead less

Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited sta ....Structure of Hadronic Excitations from Lattice Quantum Chromodynamics. Quantum chromodynamics describes the fundamental strong interactions between quarks and gluons as they compose hadrons such as the proton or neutron. Beyond these lowest-energy systems, the quantum mechanical excitation spectra display a rich and complex structure. Remarkably, little is known about the internal structure of these states. The central goal of this project is to unveil the nature of hadrons and their excited states using the first principles approach of lattice gauge theory. By elucidating aspects of hadron structure in terms of the most fundamental non-perturbative quark and gluon fields, the project will create new knowledge impacting on renowned experimental programs at international facilities.Read moreRead less
Electromagnetic structure of hadronic excitations from lattice quantum chromodynamics. Just as quantum electrodynamics describes the quantum mechanical excitation spectra of atomic systems, quantum chromodynamics (QCD) describes the excitation spectra of quark and gluon systems, such as the proton. This project will resolve the internal structure of the low-lying excitations of QCD, as being investigated at international facilities.
Alpha-particle cluster structure in light nuclei: helping and hindering fusion? A new, efficient detector system will be designed and built to answer a question never before asked - can the special structures of carbon, resembling three alpha-particles, assist rather than hinder the process of fusion with heavy nuclei? This question has arisen through my recent work published in Nature, which showed that in reactions with heavy nuclei, paradoxically both fusion and break-up into alpha-particles ....Alpha-particle cluster structure in light nuclei: helping and hindering fusion? A new, efficient detector system will be designed and built to answer a question never before asked - can the special structures of carbon, resembling three alpha-particles, assist rather than hinder the process of fusion with heavy nuclei? This question has arisen through my recent work published in Nature, which showed that in reactions with heavy nuclei, paradoxically both fusion and break-up into alpha-particles are more likely for carbon than for neighbouring nuclei. These results defy interpretation within the standard theory of nuclear fusion. The project will help to maintain Australia's world-leading position in the study of nuclear fusion.
