Dipolar quantum gases represent a new frontier in cold-atom research. Atoms with a large magnetic dipole moment interact via the long-range, anisotropic dipole-dipole potential. In large collections of atoms, it is possible to create novel superfluids, supersolids and topological phases at ultracold temperatures.
Combined with the capabilities of a quantum gas microscope we aim to measure, understand and control both the bulk properties and microscopic correlations in these exotic many-body with single-atom resolution.
Our research projects
The quantum gas microscope is currently being constructed in a new laboratory for use by researchers across a broad selection of the Australian physics community and the ARC Centre of Excellence in Future Low-Energy Electronics Technologies.
Planned studies include:
- Exotic superfluidity in mixtures of two fermionic dysprosium isotopes with tunable interactions
- Dipolar gases in optical lattices — Bose and Fermi Hubbard systems with long-range interactions
- Driven and spin-orbit coupled atomic gases to investigate nonequilibrium and topological phenomena
- Sensing of magnetic fields using a novel ultracold source and the large Dy magnetic moment.

(Right) Ultracold dysprosium atoms experience the long-range dipole-dipole interaction which depends on the relative angle of the dipoles, aligned by an external magnetic field.
