This proposal will strengthen Australia's reputation for excellence in the field of ultra-cold gases, and develop significant international linkages in this important area of physics. We will train a number of students in high-level problem solving and computing, transferrable skills ever more important in Australia's growing knowledge-based economy. Improved understanding of how BECs behave will assist in their development as sensitive measurement devices, with possible intellectual property benefits in the future as we learn to tame these unique systems.Read moreRead less
Nonlinear dynamics and chaos in Bose-Einstein Condensates on atom chips. The field of Bose-Einstein condensation (BEC) has recently seen some remarkable achievements. Researchers are now able to produce and

Researchers are now able to produce and

This project extends work in this field to the investigation of physics at the quantum/classical boundary through the study of the dynamics of BECs on atom chips. By probing a nonlinear system with a BEC we will examine how the quantum mechanics affects classically chaotic dynamics. We will also examine the classically forbidden phenomena of dynamical tunnelling and localisation.Read moreRead less

The recent production of ultracold molecular gasses paves the way for a new type of chemistry, dubbed superchemistry, which is dominated by quantum processes and which is active at zero temperature.
This project will undertake completely quantum-mechanical simulations of the atomic-molecular matter-wave dynamics and investigations of the precise quantum states in these ultralow-temperature systems. It will use novel methods adapted from laser theory, where they were used to correctly predict intrinsically quantum effects.Read moreRead less
