In addition to being important bio-molecules, they have properties which make them useful for high tech applications especially in electronics and optoelectronics. Unfortunately, our current understanding of these fascinating materials is poor. In our project we aim to solve this limiting problem. We will develop new science to explain their behaviour, and use this knowledge to create bio-compatible hi-tech materials and devices. We anticipate significant benefits from the perspectives of basic science and utilisation of biomaterials for new green technologies.Read moreRead less

Condensed matter physics has produced the technologies and materials that fuelled the digital and communications revolution. 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. These 'strongly correlated' materials include technologically important materials used in power distribution, catalysis and plastic display technologies. This p ....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. 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

Spin-liquids, antiferromagnetism, and superconductivity in organic charge transfer salts: synthesis, neutron scattering and theory. 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.

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
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.

Successful experimental demonstration of the proposed technique will considerably enhance Australia's standing in high profile areas of natural sciences. In practical terms, it can contribute to development of new generation solar cells, artificial photosynthetic centres, and a new generation of nanoprobes for biomedical applications. Because the single-molecule technique is a new and dynamic field, opportunities exist for significant commercial property development. The project will also train a number of students in several fields of high technology, all of which are likely to have high demand in the future.Read moreRead less

Neutron scattering enables new science across a broad range of disciplines, and for this reason it is undergoing major expansion in the USA, Europe, Japan and Australia. Various diffactometers and spectrometers have recently been built at ANSTO, but an instrumental option for a high-throughput cross-discipline spectroscopy is urgently needed. Fortunately, it is fairly straightforward to add this type of option to an existing spectrometer that will broaden its user-base from specialised applications in physics to more general applications in physics, chemistry, materials-science and biology. This additional option provides a totally new way for Australian scientists to study atomic and molecular motions. Read moreRead less
