Low-dimensional quantum systems. The theory of integrable systems of statistical mechanics and quantum field theory is currently one of most rapidly developing and fascinating subjects in theoretical physics and mathematics.
It allows to obtain an exact description of strongly-interacting quantum systems in one or two space dimensions and provides fundamental tools for understanding of critical phenomena and physics of small systems like quantum wires, carbon nanotubes and Josephson junctions ....Low-dimensional quantum systems. The theory of integrable systems of statistical mechanics and quantum field theory is currently one of most rapidly developing and fascinating subjects in theoretical physics and mathematics.
It allows to obtain an exact description of strongly-interacting quantum systems in one or two space dimensions and provides fundamental tools for understanding of critical phenomena and physics of small systems like quantum wires, carbon nanotubes and Josephson junctions. The project addresses two particular problems in this field: the three-dimensional lattice model with continuous spins and calculation of form factors in a two-dimensional massive field theory with a supersymmetry.

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. 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 systems. The expected outcome is a position of world leadership in the theoretical understanding of the dynamics of atom lasers, mixed atom-molecule BECs, and fragmented BECs in optical lattices.Read moreRead less

Detection and Control of Ultracold Atoms. Australia is at the forefront of research into atom lasers, a device that may be as important to science and technology this century as the laser was in the last. This project will provide important theoretical tools for developing the atom laser from an object of intrinsic interest to a useful tool. It will develop Australian scientific expertise in this area, and provide training for the next generation of Australian scientists.
Multiple atomic photoionization in superstrong electromagnetic field. Correlation, or entanglement, of electrons in matter governs many important phenomena in nature, such as chemical reactions, superconductivity and ferromagnetism. However, it is the many-electron processes in atoms which allow the study of electron correlations most clearly.
