Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects. This pr ....Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects. This project is devoted to a theoretical investigation of weak interaction effects in atoms, molecules, and nuclei. It will provide improved tests of unified theories.Read moreRead less

Violation of fundamental symmetries and test of unification models. This project is devoted to a theoretical investigation of the atomic and nuclear effects of parity and time invariance violation. Measurements of these effects provide accurate tests of unification theories of elementary particles. Effects of weak interactions are normally very small, and we want to look for possibilities to enhance these effects. We also plan to search for new effects and tests of the unification theories an ....Violation of fundamental symmetries and test of unification models.

Novel approaches to studies of violations of fundamental symmetries of nature. This project will contribute to research at the leading edge of fundamental physics. This is an international project that incorporates intensive collaboration with US experimental groups which will base their work on our calculations. Ultimately these studies will shed light on the origin of matter-antimatter asymmetry in the Universe.
Topological order and anyons: quantum engineering of emergent physics. Australia is recognized as one of the world leaders in the area of quantum information and computation. As a frontier technology with tremendous potential but engineering challenges it is vital we expand our theoretical landscape to better steer experimental development.

Australia is recognized as one of the world leaders in the area of quantum information and computation. As a frontier technology with tremendous potential but engineering challenges it is vital we expand our theoretical landscape to better steer experimental development. A promising new paradigm is topological quantum computation which uses particles with exotic statistics called anyons that do not exist naturally in three dimensions but can be engineered to emerge in two dimensional spin lattices. Our bottom up research program would help place Australia at the forefront of these ideas. As a field which combines tools from mathematics, computer science, and physics this project will provide world class training to young researchers.Read moreRead less
Physics of Self-Organization: From Space Plasmas to Brain Dynamics. Nature displays intricate, self-organized structures and behaviors that often emerge from simple underlying rules. This project will explore and unify fundamental regimes of self-organization, and apply them to explain phenomena in space, plasma, and wave physics, including making key inputs to the international STEREO space mission. In a core initiative, sophisticated tools from these fields will be transfered and adapted to a ....Physics of Self-Organization: From Space Plasmas to Brain Dynamics.

This project will explore and unify fundamental regimes of self-organization, and apply them to explain phenomena in space, plasma, and wave physics, including making key inputs to the international STEREO space mission. In a core initiative, sophisticated tools from these fields will be transfered and adapted to analyze self-organized brain dynamics, leading to the first self-consistent "working brain" model. The results of this innovation will be used to develop new imaging technologies, to probe brain function via the new windows they open, and to exploit them commercially.Read moreRead less
Quantum plasmas. Quantum effects become important under extreme conditions, and a newly developing field of "quantum plasmas" is motivated by two different extremes for ionized systems. One is in very small electronic devises, where electrons carrying the currents become wave-like with a wavelength comparable with the size of the device. The other is in the extremely intense optical light spots now available by focusing high-power lasers. In this project we propose to take a leading role in the ....Quantum plasmas.

Dynamics of Bursty Waves in Space and Astrophysics. Waves in space plasmas typically occur in bursts with widely variable fields and persist, with their driving particle distributions, for unexpectedly long times. These features cannot be accounted for with standard plasma theory but are explained naturally by stochastic growth theory (SGT). Recent observations show SGT to be widely applicable in space. We propose to make SGT fully quantitative, by studying the dynamical evolution to SGT in gene ....Dynamics of Bursty Waves in Space and Astrophysics.

These features cannot be accounted for with standard plasma theory but are explained naturally by stochastic growth theory (SGT). Recent observations show SGT to be widely applicable in space. We propose to make SGT fully quantitative, by studying the dynamical evolution to SGT in general and in known SGT systems, and to develop and observationally test theories based on SGT and associated wave/radiation processes for major, long-unexplained radio phenomena in space and in astrophysics.
