Highly frequency stable oscillators may be used as frequency or timing standards (clocks) and have commercial application as well as application of testing fundamental physical principles. This project is to continue the development of novel frequency standards in collaboration with some of the best research institutes in France funded by the French Space Agency (CNES). With the advent of the International Space Station and new atomic clocks, the physics community is embarking on an experimental program that will make use of the microgravity environment of space. Combined with the new improved timing it will be possible to perform new experimental tests of general and special relativity, tests for drifts in the fine structure constant and tests for a preferred direction of the speed of light at unprecedented sensitivity.Read moreRead less

Low Energy Effective Actions in Supersymmetric Gauge Theories. The quest for a unified quantum theory of all the fundamental interactions of Nature, including gravity, is a major goal of modern physics. Superstring theory is at present the only plausible candidate. This theory makes nontrivial predictions (non-renormalization theorems) about the low energy structure of certain supersymmetric gauge theories (the Standard Model of particle physics is a special gauge theory).

The quest for a unified quantum theory of all the fundamental interactions of Nature, including gravity, is a major goal of modern physics. Superstring theory is at present the only plausible candidate. This theory makes nontrivial predictions (non-renormalization theorems) about the low energy structure of certain supersymmetric gauge theories (the Standard Model of particle physics is a special gauge theory). This project will develop new tools for the computation of low energy effective actions, which will then be used for a detailed analysis of the non-renormalization theorems governing the low energy dynamics of supersymmetric gauge theories.

The aim of this project is to establish a state-of-the-art triple-axis x-ray diffraction facility capable of non-destructively analysing complex semiconductor materials and structures investigated by all Australian semiconductor-growing groups. Growers and device engineers will be able to control growth processes accurately and correlate device performance with structural analysis. Modern triple-axis instruments can also be used for high-resolution texture analysis and surface reflectivity measurements on numerous types of materials. Thus chemists, geologists, and materials scientists with interests outside of the semiconductor growth community will gain substantial benefit from this instrument for the investigation of materials of technological and economic importance.Read moreRead less

A well known example is the giant magnetoresistance, a phenomena discovered over fifteen years ago that now plays a key role in current high density magnetic disc drives. Future developments will involve spin dependent transport through structures wherein quantum interference effects will be important. Two basic problems facing the construction of a complete theory of transport in such ?mesoscopic? conductors will be solved in this project. The results will provide important insights into the dynamics of spin transport through structures such as magnetic nano-wires.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.

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.
