We have been world-leaders in the field of atomic collision theory for almost a decade, and now, utilising the latest software and hardware, will have the capacity to extend the numerical techniques to a vast range of collision systems of interest to science and industry, where visualisation and sheer computer power will play a major role in both

The proposed project is designed to enable one of the most exciting and least studied components of the gravitational wave spectrum, the Astrophysical Gravitational wave Background (AGB), to be detected by Advanced LIGO. It will extend the Australia-US collaboration in Advanced LIGO to include modeling, simulation and detection methods of the AGB and the study of the optical noise in LIGO and Advanced LIGO type systems. In particular we plan to search for anomalous noise sources and, especially those arising in high optical power cavities that could limit detection of the AGB.Read moreRead less
Investigation of 1/f noise mechanisms in HgCdTe heterostructure IR photodiodes. Since the performance of any photon detector is defined by its signal to noise ratio, the reduction of noise generating mechanisms is equally important to improvement of the signal. In this project we propose to carry out, for the first time, a comprehensive analysis of noise generating mechanisms in HgCdTe detectors using recently developed, two-dimensional analysis procedure.

In this project we propose to carry out, for the first time, a comprehensive analysis of noise generating mechanisms in HgCdTe detectors using recently developed, two-dimensional analysis procedure. The main objective of this project is to prove that 1/f noise in HgCdTe photodetectors is caused by dark current fluctuations in the high electric field regions of the detector structure. The primary outcome of this work will be the first comprehensive two-dimensional device model that can predict 1/f noise in a semiconductor device.Read moreRead less

This project will strengthen Australian "know how" and expertise, and place us in a position to participate in current and future space missions. Moreover, this represents an opportunity for high profile involvement as the only southern hemisphere user of the most accurate space clock ever developed, which will likely involve the order of 30 institutes worldwide. This work necessarily includes collaboration with the world's elite metrological institutes.Read moreRead less
Exploring Synergies between Frontier Microphotonics and Advanced Time and Frequency Technology. Recently scientists have developed the means to manufacture objects that are on the same microscopic scale as light itself.

These structures can deliver exquisite control of the properties of the light beams. Our existing research has been aimed at developing some of the world's most precise measurement tools based on clocks and the pure colours generated by lasers. By combining these two technologies, both of which lie at the extreme limit of precision, we will develop a new generation of technology for fundamental science objectives as well as for industrial needs.Read moreRead less
Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools ....Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools and measurement techniques that will elucidate the flow-structure dynamics leading to new diagnostic and improved treatment methods. Simulating the effect of treatment on any individual will permit it to be chosen to maximise its efficacy for a problem that costs the nation an estimated $2 Billion per year in lost productivity.Read moreRead less
