The role of low-energy excited states in solar-energy capture. This project aims to determine the nature and role of the lowest-energy excited states in most natural photosynthetic reaction centres and light-harvesting complexes. The lowest-energy states of bacterial reaction centres are critical to function and are used as a paradigm in artificial organic solar-energy capture, but for most photosystems their nature remains unknown. The project aims to answer the critical question of why they do ....The role of low-energy excited states in solar-energy capture. This project aims to determine the nature and role of the lowest-energy excited states in most natural photosynthetic reaction centres and light-harvesting complexes. The lowest-energy states of bacterial reaction centres are critical to function and are used as a paradigm in artificial organic solar-energy capture, but for most photosystems their nature remains unknown. The project aims to answer the critical question of why they do not actually prevent function. It is expected that both the outcomes obtained and techniques developed will be directly relevant to solar-energy device design. The project will apply five existing, complimentary and purposely built spectrometers as well as quantum electronic and nuclear simulation techniques to identify and characterise three key systems.Read moreRead less
HARMONIC ANALYSIS AND BOUNDARY VALUE PROBLEMS FOR ELLIPTIC SYSTEMS. It is of the utmost necessity for Australia to develop the theoretical

Propagation of singularities for the Schrodinger equation. The time-dependent Schrodinger equation governs the evolution of quantum particles. In this project we aim to use new techniques from mathematical scattering theory to analyse solutions of the Schrodinger equation and obtain sharp bounds on their singularities. Controlling such singularities will allow us to deduce quantitative bounds on the number of eigenvalues in certain situations, and provide new techniques for studying nonlinear Sc ....Propagation of singularities for the Schrodinger equation.

Physics of Risk: new tools to survey the Australian market and beyond. The lives of most Australians depend on the dynamics of financial markets that affects investments, savings, business, employment, growth, wealth and -ultimately- the daily functioning of our society. Understanding, monitoring and managing the dynamics of financial markets is of crucial importance to policy-makers, financial institutions and businesses that are increasingly faced with managing risk, planning strategies and ta ....Physics of Risk: new tools to survey the Australian market and beyond. The lives of most Australians depend on the dynamics of financial markets that affects investments, savings, business, employment, growth, wealth and -ultimately- the daily functioning of our society. Understanding, monitoring and managing the dynamics of financial markets is of crucial importance to policy-makers, financial institutions and businesses that are increasingly faced with managing risk, planning strategies and taking decisions in an increasingly complex market-place. The project is also of importance to the continued evolution of physics in this country contributing to the emergence of a strong new area of statistical physics concerned with the ?real world? in a manner hitherto unknown.Read moreRead less
HARMONIC ANALYSIS, BOUNDARY VALUE PROBLEMS, AND MAXWELL'S EQUATIONS IN LIPSCHITZ DOMAINS. Boundary value problems for partial differential equations arise naturally when physical problems are expressed in mathematical terms.

Boundary value problems for partial differential equations arise naturally when physical problems are expressed in mathematical terms. This project concerns the systematic development of the harmonic analysis of partial differential operators, and of the corresponding boundary integrals in order to solve such problems on irregular regions. Particular emphasis is given to studying the behaviour of electromagnetic waves both inside and outside irregularly shaped surfaces, and their propagation through it.Read moreRead less
Harmonic analysis of differential operators in Banach spaces. This proposal aims to develop harmonic analysis (the mathematical tools used in digital music and photography) in new contexts. It focuses on boundary value problems (the theory behind medical or geological imaging) and stochastic equations (which describe phenomena with random components such as the behaviour of financial markets).

Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in ....Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in mixtures. The current proposal is aimed at introducing new technology into the Australian National Beamline Facility that will greatly improve the quality and quantity of experiments that can be performed and extend studies into dilute solutions and protein samples.Read moreRead less

This project aims to assess the function of proteins by monitoring their motions using new nuclear magnetic resonance (NMR) spectroscopy techniques. As snapshots of 3D protein structures have been determined by crystallography, the new tools are designed to analyse functionally important motions in solution. A facility for ultrafast (> 100 kHz) magic angle spinning NMR spectroscopy of proteins in the semi-solid state will bring cutting-edge know-how to Australia and allow the interrogation of 3D structure and dynamics in selected protein regions. The expected outcomes of the project will have immediate benefits for the rational engineering of biocatalysts and in the design of lead compounds in drug development.Read moreRead less
