Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment.

A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.Read moreRead less
Existence and Stability of a Model for Three-Dimensional Toroidal Plasma Equilibria. There is great physical interest in modelling strongly non-axisymmetric toroidal plasmas, but fundamental existence problems have made rigorous numerical analysis so far impossible. We seek to overcome this by investigating a class of idealized, but physically motivated, magnetohydrodynamic equilibria with stepped pressure profiles for which existence in the neighbourhood of axisymmetry has been proven. We will ....Existence and Stability of a Model for Three-Dimensional Toroidal Plasma Equilibria. There is great physical interest in modelling strongly non-axisymmetric toroidal plasmas, but fundamental existence problems have made rigorous numerical analysis so far impossible. We seek to overcome this by investigating a class of idealized, but physically motivated, magnetohydrodynamic equilibria with stepped pressure profiles for which existence in the neighbourhood of axisymmetry has been proven. We will (i) develop numerical techniques to extend these piece-wise Beltrami states far away from axisymmetry (ii) develop practical tests to determine when existence breaks down (iii) analyze the frequency spectrum of small oscillations about such equilibria (iv) extend the model to two-fluid MHD.Read moreRead less

Burning Plasmas: resolving energetic particle physics for the International Thermonuclear Experimental Reactor (ITER). Fusion power is a zero greenhouse gas emitting technology, which if realised, offers millions of years of base-load electricity. This promise has prompted the international community to accelerate fusion energy development, principally via support of the next-step technology-enabling experiment, International Thermonuclear Experimental Reactor (ITER).

Fusion power is a zero greenhouse gas emitting technology, which if realised, offers millions of years of base-load electricity. This promise has prompted the international community to accelerate fusion energy development, principally via support of the next-step technology-enabling experiment, International Thermonuclear Experimental Reactor (ITER). Our project addresses a grand science challenge facing ITER and fusion power: can the products of reaction be kept confined and therefore self-heat the plasma? The answer will affect both the ITER program, and the viability of fusion power. This project provides a low-cost high-impact contribution to the science base for the $16 billion ITER project, whilst growing Australian capability in this strategically important technology.Read moreRead less
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.

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
Synthesis of Unique Mesoporous Graphitic Carbons and their Application to Fundamental Problems in Adsorption Science.

The development of synthesis techniques to create porous graphitic carbons with highly ordered pore structures, easily accessible pore volume and good electrical conductivity can underpin technological advancements in many industrial applications such as energy storage, removal of pollutants from exhaust streams, direct-methanol fuel cells and lithium ion batteries. Techniques developed in this project are also applicable to creating other materials important to advanced sensors and optoelectronics. The fundamental study of water adsorption and hysteresis using these carbons will help us create better models for adsorption. This will underpin theoretical studies, characterisation and optimisation of carbon materials into the future. Read moreRead less

Nucleosynthesis today and tomorrow. Australia is a recognised world leader in understanding the interiors of stars and how they make the elements seen all around us, from Carbon to Gold and beyond. This project combines Australian theoreticians with the world's largest telescopes and computers, as well as the latest laboratory instruments and techniques, to further our understanding of where all the elements originated.
