Parametric Brain Imaging via Modeling and Analysis of Electroencephalographic Signals. Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods. This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data. T ....Parametric Brain Imaging via Modeling and Analysis of Electroencephalographic Signals. Parameters of brain function and physiology will be spatially imaged with high time resolution via their effects on electroencephalographic (EEG) signals, a form of imaging that is impossible with existing methods. This will be achieved by improving existing physiologically-based models of the generation of EEGs and developing analysis tools based on fitting of model predictions to multielectrode EEG data. The results will be used to probe spatiotemporal features of EEGs in normal subjects to explore the underlying fundamental mechanisms and to infer novel parameter variations of practical relevance.Read moreRead less
Many-body problems. The discovery of new superheavy elements, chemical evolution of the Universe, nuclear reactions deep under the Coulomb barrier in nuclear reactors, in stars and during the Big Bang Nucleosynthesis, accuracy of precise atomic clocks, consistency of the Standard Model in strong fields are among the most vital problems of modern science.

The discovery of new superheavy elements, chemical evolution of the Universe, nuclear reactions deep under the Coulomb barrier in nuclear reactors, in stars and during the Big Bang Nucleosynthesis, accuracy of precise atomic clocks, consistency of the Standard Model in strong fields are among the most vital problems of modern science. This project suggests several new ideas in these areas, which are based on knowledge accumulated in different research fields. The outcomes of the research will help Australia to build up a "critical mass" of scientific expertise, which is necessary to place and keep it among leaders in these frontier areas of physics, and to train the next generation of experts in these fields.Read moreRead less
Modelling quantum dynamics of electronic excited states in complex molecular materials. Understanding new materials that are the basis of new sources of renewable energy sources represents a major scientific challenge. Many of these materials are composed of large organic molecules containing hundreds of atoms.

Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects. This pr ....Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects.

The laser sources generally do not have simple (Gaussian) distributions. The applicant has recently developed a model, describing free propagation of complex (non-Gaussian) laser beams. This project seeks to develop a comprehending model for laser beams propagation through complex optical systems. The effects of various optical elements will be defined employing a novel method known as SAFE (Stable Aggregate of Flexible Elements) which is a compromise between geometrical and physical optics. Applying this model to micromachining and optical data storage (ODS), which need high beam quality (low divergence and good focussibility), enable accurate predictive capability critical to the optimisation of micromachining and ODS designs.Read moreRead less
