A High-Throughput Neutron Spectrometer for The Study of Atomic and Molecular Motion at ANSTO. Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed.

Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed. Fortunately, it is fairly straightforward to add this type of option to an existing spectrometer that will broaden its user-base from specialised applications in physics to more general applications in physics, chemistry, materials-science and biology. This additional option provides a totally new way for Australian scientists to study atomic and molecular motions. Read moreRead less
Modelling Superconducting Quantum Devices. The capability to incorporate quantum mechanical systems into electronic circuits leads to devices with fundamentally new properties. These devices are very sensitive to their environment, so can be used as sensitive sensors. In the extreme, with many such devices connected together, it would lead to a full scale quantum computer, which has the capacity to perform tasks that are unfeasible on an ordinary computer. This proposal aims to characterise ....Modelling Superconducting Quantum Devices.

Quantum materials are a diverse class of materials whose unusual properties emerge from the strong interactions between electrons. Many have metallic phases with a low electrical conductivity (bad metals). The aim is to understand and characterise this quantum state of matter and how it emerges from the constituent electrons. An expected outcome will be falsification of specific theoretical models (based on techniques from string theory) and development of concepts that can be used to interpret experiments, including on ultra-cold atomic gases. Projected future benefits include new insights and concepts that may aid the design and synthesis of new materials for applications based on superconductivity, thermoelectricity and magnetoresistance.Read moreRead less
