This theoretical project uses fermionic matterwaves to increase the sensitivity of atom interferometers for precision measurement. The focus on fermionic atoms has two main advantages: (1) greater control over interactions (since at ultracold temperatures, interactions between the same species  - which is a source of phase noise for bosonic atoms - is suppressed) and (2) the ability to harness the correlations and entanglement that are unique to fermions.  Correlations between particles are crucial for increasing the precision of an interferometer beyond the standard quantum limit.  For fermions, correlations come for free due to the Pauli exclusion principle.  This project will model the splitting, propagation (including intrinsic broad-band effects) and recombination of fermionic matterwaves in order to evaluate the effectiveness of a many-body fermion interferometer.

 By modelling the preparation of correlated matterwaves and their quantum dynamics through novel interferometer schemes, we will enable levels of precision beyond what is possible with independent atoms. This research will lead to a new generation of practical atomic measurement devices, for investigations into fundamental physics and for new technologies

This project will draw on the expertise in ultracold atoms, atom interferometry,  and simulation methods that is available in the quantum atom optics group.  As a computationally intensive project, it will make use of the state-of the art computational facilities at UQ
