Materials have driven the digital revolution. Understanding and controlling silicon has allowed us to make smaller devices that perform better; an iPhone has more computing power than a PC had ten years ago. For this remarkable trend to continue future devices will need to utilise novel physics and be made from new materials. We will grow crystals of organic molecules, whose properties derive from the correlated motion of the electrons in these materials. State-of-the-art 'neutron scattering' experiments will test theories of the way the electrons behave in these materials. We will answer fundamental questions, which is an important first step towards harnessing such effects for future technology.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.

Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also ....Fluctuations in the properties of nonequilibrium fluids and the influence of thermostatting mechanisms. The behaviour of nonequilibrium fluids will be studied by combining ideas from liquid state theory, statistical mechanics and dynamical systems theory. This work will result in development and testing of mathematical expressions (Fluctuation Theorems) that are consistent with the Second Law of Thermodynamics, which determines the direction of any change in any macroscopic system, but are also applicable to microscopic systems. The expressions will determine the probability that finite sized systems will violate the Second Law for small periods of time and will therefore contribute to development of a fundamental understanding of microscopic systems and the development of nanotechnology.

Hydrogen Absorption by Nanostructured Carbons. Carbon-based materials show great promise for clean energy storage through the absorption and desorption of hydrogen. The project aims to use powerful theoretical and experimental methods to resolve the controversy that surrounds reports of massive hydrogen absorption by nanostructured carbons, by understanding why particular structures should or should not absorb hydrogen atoms or molecules. We will particularly study and model intercalated graphit ....Hydrogen Absorption by Nanostructured Carbons. Carbon-based materials show great promise for clean energy storage through the absorption and desorption of hydrogen. The project aims to use powerful theoretical and experimental methods to resolve the controversy that surrounds reports of massive hydrogen absorption by nanostructured carbons, by understanding why particular structures should or should not absorb hydrogen atoms or molecules. We will particularly study and model intercalated graphite and nanotubes made in Australia. Their hydrogen capacity will be compared to the US DOE target of 6.5 weight percent for viable automotive hydrogen fuel storage. Reproducibly exceeding this target would constitute a great advance in the field.Read moreRead less

Over the last decade a revolution has been taking place in nonequilibrium statistical mechanics [Physics Today, Sept, 2002]. This revolution is characterized by adapting the mathematical theory of chaos to nonequilibrium statistical mechanics. Fundamental new theorems and algorithms for computing transport coefficients have been derived. The CIs have played a key role in this revolution. We seek to broaden these developments by: generalizing a theorem which relates transport coefficients to chaoticity; detailed studies of the influence of thermostatting mechanisms on nonequilibrium chaoticity and fluctuations, and by understanding the range of applicability of a nonequilibrium fluctuation theorem for non-isoenergetic systems.Read moreRead less
