Project Title

Atom Laser Modelling

Brief Description for General Publications

This project will comprise the numerical component of a combined theoretical and experimental investigation into controlling the quantum state of a Bose-Einstein condensate (BEC), outcoupling it to form an atom laser, controlling the state of the atom laser, and using it for atom interferometry. The numerical modelling will support the Rubidium and metastable Helium BEC experimental groups at the ANU, as well as the associated theory group in the Department of Quantum Science. The project will model experimental results, determine optimal schemes for feedback and control of a BEC, and examine schemes for creating atomic fields with non-classical properties such as squeezing and entanglement. It will also develop methods for making non-perturbative quantum field calculations for these systems. Both the three-dimensional semiclassical and one-dimensional quantum field theory models require supercomputer-level performance to be completed in reasonable time frames, or in some cases at all.
