Computational methods in atomic collision theory. We will develop computational methods for solving interactions between particles on the atomic scale. Computational problems, of particular interest to the industry partner, are the treatment of large-scale ill-conditioned linear systems, and the extension of the Gaussian molecular structure package to collision physics.

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 astrophysical stochastic background of gravitational waves and detection by advanced high optical power interferometers: an Australia-US collaboration. 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 ....The astrophysical stochastic background of gravitational waves and detection by advanced high optical power interferometers: an Australia-US collaboration. 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.

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. 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
