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

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.

Physics of extreme brightness temperatures in radioastronomical sources. Pulsars and some quasars are so very bright that the conventional explanation for radioastronomical emission from other sources either does not apply to them, or presents unsolved problems. We see (in radio waves) these sources through the interstellar medium which acts like a wrinkled pane of glass in distorting the image. New scientific ideas and methodologies are proposed here and will be explored in the project, with th ....Physics of extreme brightness temperatures in radioastronomical sources.

We see (in radio waves) these sources through the interstellar medium which acts like a wrinkled pane of glass in distorting the image. New scientific ideas and methodologies are proposed here and will be explored in the project, with the objective to understand these sources and to extract information on their propreties and those of the interstellar medium.

Interstellar Gas Dynamics. The conversion of interstellar gas into stars is a key process in the life-history of galaxies and the formation of planetary systems. Star formation takes place within a heterogeneous, dynamic cloud, and entails a million-fold contraction controlled by a complex interplay between gravity, magnetic forces, ionisation balance, chemical reactions and particles of interstellar dust. Previous modelling has adopted inappropriate approximations for the evolution of the mag ....Interstellar Gas Dynamics. The conversion of interstellar gas into stars is a key process in the life-history of galaxies and the formation of planetary systems. Star formation takes place within a heterogeneous, dynamic cloud, and entails a million-fold contraction controlled by a complex interplay between gravity, magnetic forces, ionisation balance, chemical reactions and particles of interstellar dust. Previous modelling has adopted inappropriate approximations for the evolution of the magnetic field. This research will bring a rigorous treatment of magnetic diffusion to bear on the theory of cloud evolution, shock waves, star formation and protoplanetary discs.

Violation of the fundamental symmetries is predicted by unification theories of elementary particles. The aim of this project is to propose new enhanced effects of parity, time reversal and Lorentz invariance violations and perform their calculations needed to test unification theories in atomic and nuclear phenomena. By-products of this project include development of high precision computer codes for atomic calculations and theory of processes involving atoms and nuclei in chaotic excited states. These codes and theory are expected to have numerous applications (e.g. search for Dark Matter and atomic spectra of superheavy elements, atomic clocks and electron and photon processes).

From dark matter to atomic physics. Very little is known about dark matter except that it is present in our Universe in abundance. The project aims to guide the search for dark matter particles (and study related phenomena, for example, baryogenesis). The guiding idea is that these particles interact, albeit weakly, with atoms and hence are able to ionise them, which is a detectable process.
