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

Summary
Access for Australian Researchers to Advanced Neutron-Beam Technique. Neutron scattering is one of the most powerful and important investigative tools in the study of materials. Australia has only a low-flux neutron source, HIFAR, which provides no cold or hot neutrons. This excludes large, important areas of science, such as functional films, polymers, self-assembly systems, biological materials, colloids and emulsions, and real-time in-situ studies.

This excludes large, important areas of science, such as functional films, polymers, self-assembly systems, biological materials, colloids and emulsions, and real-time in-situ studies.
This application aims to continue Australia's parnership with the world's most intense neutron source, ISIS in the UK, in order to sustain the considerable Australian scientific momentum which now relies on ISIS.
The outcome will be new science that cannot be generated solely within Australia.Read moreRead less

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.

Fluid properties and chaotic dynamics in equilibrium and nonequilibrium states. Over the last decade a revolution has been taking place in nonequilibrium statistical mechanics [Physics Today, Sept, 2002].

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
Algebraic approach to exactly soluble models for disordered systems. In nanoscience there are a diverse range of systems in which disorder, randomness, or noise can play a significant role. Examples range from quantum wires to qubits to unzipping DNA.
Even the simplest mathematical models for systems in the presence of disorder have a rich mathematical structure because they can be formulated in terms of Lie algrebras or diffusion on a curved surface.

The scientific importance of condensed matter physics is indicated by the fact that ten Nobel prizes have been awarded for work in this field since 1990. This proposal brings together world leading chemists, experimental physicists and theoretical physicists from Australia, USA and UK to work on highly interdisciplinary projects designed to discover how quantum mechanics leads to the novel properties of chemically complex materials. Such materials will be of central importance to the technologies of the future such as computer memories and the superconducting magnets in hospital MRI machines.Read moreRead less
Strongly correlated electron models for organic superconductors. In conventional metals such as copper the interactions between the electrons do not qualitively change the behaviour of the material. However, over the last few decades many materials have been discovered whose behaviours are dominated by the interactions between electrons.

However, over the last few decades many materials have been discovered whose behaviours are dominated by the interactions between electrons. These 'strongly correlated' materials include technologically important materials used in power distribution, catalysis and plastic display technologies. This project will combine theoretical and experimental methods from chemistry and physics in an effort to explain the novel behaviours seen in certain classes of organic strongly correlated materials. This understanding has the potential to impact future electronic devices and advanced materials.Read moreRead less
