Dynamics of Interacting Bose Gases/Fluids in Atomic and Condensed Matter Systems. This research would raise the profile of Australian theoretical physics in two key areas of fundamental research. The work on correlated electron fluids will be directly related to the breakdown of the quantum Hall effect, which is used to maintain the resistance standard, with one possible outcome being the improvement of the accuracy of this standard.

This research would raise the profile of Australian theoretical physics in two key areas of fundamental research. The work on correlated electron fluids will be directly related to the breakdown of the quantum Hall effect, which is used to maintain the resistance standard, with one possible outcome being the improvement of the accuracy of this standard. The work on the dynamics of dilute gas Bose-Einstein condensates will promote understanding of such systems and propose knew methods of exploring this novel state of matter. Drawing analogies between these two diverse subjects will promote a greater understanding of both research fields. The work would be in collaboration with internationally renowned research groups.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.

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.

Dynamics of multi-component matter waves. The recent observation of Bose-Einstein condensation (BEC) in weakly interacting ultracold gases has opened the door to the field of coherent matter-wave optics. When the BEC is treated within a mean-field approach the equations resemble those for the propagation of light in nonlinear media. The main aim of this project is to bring our broad and deep nonlinear optical expertise to bare on the classical nonlinear dynamics of multi-component BEC like syste ....Dynamics of multi-component matter waves.
