Spin-dependent interactions: a fundamental basis for spin-electronics. This project will establish a comprehensive understanding of spin-dependent interactions and correlated behaviour of multi-electron systems that are responsible for spin-relaxation, spin transport and spin coherence in spin-electronic devices. Our approach is based on the spin-resolved two-electron coincidence spectroscopy that is inherently suited for studying electronic correlations.

This project will establish a comprehensive understanding of spin-dependent interactions and correlated behaviour of multi-electron systems that are responsible for spin-relaxation, spin transport and spin coherence in spin-electronic devices. Our approach is based on the spin-resolved two-electron coincidence spectroscopy that is inherently suited for studying electronic correlations. Systematic investigations of spin-dependent interactions in atoms, molecules and ultrathin films will increase understanding of magnetic (spin) properties of artificially structured materials with reduced dimensionality for the benefit of nanotechnology. This understanding will be used to design and control, at the quantum mechanical level, the building blocks of spin-electronic devices.Read moreRead less

This proposal brings together significant research groups in La Trobe University, Monash University, the University of Western Australia, Newcastle University and Sydney University to establish a unique materials characterisation facility which will enable surface and magnetic structures of technologically significant materials to be determined. It will support developments in the areas of new magnetic phenomenon which is used in magnetic sensing and in the exploration of processes of size reduction for electronic devices. It will enable this new, world leading technology, to be applied to surface structures relevant in the areas of nanotechnology and catalysis.Read moreRead less
Measurement of the spatial distribution of temperature and velocity in lakes using Acoustic Tomography. This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity. The challenges with lake acoustic tomography are the accuracy required in the travel time measurements over shorter distances, acoustic losses due to reflections and ensuring enough rays travel through the thermocline, the region of greatest inte ....Measurement of the spatial distribution of temperature and velocity in lakes using Acoustic Tomography. This project will investigate the use of acoustic tomography in lakes to continuously measure the lake-wide distribution of temperature and velocity. The challenges with lake acoustic tomography are the accuracy required in the travel time measurements over shorter distances, acoustic losses due to reflections and ensuring enough rays travel through the thermocline, the region of greatest interest in lakes. A pilot experiment in a deep lake will investigate the quality of travel time measurements computed from rays travelling through the thermocline of a strongly stratified lake. This has wide applications for the water quality management of lakes and reservoirs.Read moreRead less
Acoustic observation of Antarctic ice rifting and calving events using remote hydroacoustic listening stations. The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level aro ....Acoustic observation of Antarctic ice rifting and calving events using remote hydroacoustic listening stations. The calving activity of the Antarctic ice shelves is one of the major indicators of global climate change. Global warming induced by an increase in atmospheric CO2 will affect the Antarctic Ice Sheet, primarily in form of disintegration of the Antarctic ice shelves surrounding the continent. The processes of calving on the ice shelves may lead to a substantial increase of sea level around the world, with devastating effects on the continental coasts and low-lying islands. The method of remote acoustic observations investigated in this project is a new approach to the problem of creating an efficient and cost effective system to monitor rifting and calving of the Antarctic ice shelves.

Redefining Temperature. The international system of units, which is at the basis of every accurate measurement, requires coherent definitions for its basic units (eg. metre, second, kelvin). Unfortunately, at the moment this is not so, and a global call has gone out to redefine every basic unit in terms of fundamental constants, which are by definition the same anywhere and anytime. This project will develop a new laser-based approach to measuring temperature which can be widely deployed and us ....Redefining Temperature. The international system of units, which is at the basis of every accurate measurement, requires coherent definitions for its basic units (eg. metre, second, kelvin). Unfortunately, at the moment this is not so, and a global call has gone out to redefine every basic unit in terms of fundamental constants, which are by definition the same anywhere and anytime. This project will develop a new laser-based approach to measuring temperature which can be widely deployed and uses fundamental principles for its operation: this can bring accuracy to thermometry in industry for the first time. These outcomes will generate high-level recognition for this Australian project and provide opportunities for high level research training.Read moreRead less

Uncovering highly excited states of quantum three body systems using new technological approaches. Experimental studies of the fundamental structure of quantum three body systems are proposed to uncover long-lived highly-excited states. Ultra-fast timing technology applied to a variant of electron time-of-flight studies will form the basis of the measurement system to be used at a world-class synchrotron light source.

While our world is made of matter, all particles have anti-particles and the most abundant is the positron, the electron's antiparticle. It is the "workshop" for most anti-matter studies, particularly for the characterization of materials, including gases, polymers, insulators, thin films and surfaces, as well as the development of new and novel, nano-structured materials.
