Atomic and molecular physics research

The physical properties of atoms and molecules, underpin the nature of all matter and as such their study represents a fundamental discipline. The School has a number of research programs in this area.

The School partially hosts the ARC Centre of Excellence for Quantum Atom Optics, and plays a leading role in the development of laser and magnetic cooling systems designed to create Bose Einstein condensates and atomic beams. RSPhysSE recently became one of only four groups in the world to achieve a BEC using excited metastable helium.

The School is a partial host to The ARC Centre of Excellence for Antimatter-Matter Studies whose experimental and theoretical program is based around the study of the interaction of positrons with matter. Anti-particles give a unique insight into the structure and properties of matter with applications in fundamental science, medicine and nanoscale materials. This work is complimented by a strong research effort in electron physics, especially electron momentum spectroscopy.

We also study ultra violet physics and problems of atmospheric, aeronomic and astrophysical significance, relating to the interaction of vacuum ultraviolet radiation with gaseous matter. Such studies are fundamental to understanding the distribution of ozone, and the behaviour of atmospheric pollutants. Quantum mechanical modelling of spectra is used to interpret photoabsorption spectroscopy measurements.

We apply the most advanced quantum-mechanical modeling to resolve electron motion in atoms and molecules on the atto-second (one quintillionth of a second) time scale.  Our theoretical modeling, based on a rigorous, quantitative description of correlated electron dynamics, provides insight into new physics taking place on the atomic time scale.

The idea of equilibration is ubiquitous throughout nature. Out-of-equilibrium dynamics – be it caused by a disturbance and subsequent “rethermalisation”, or by passing through a phase transition – is a difficult question to characterise. This project looks at both equilibration and phase transitions in a Bose-Einstein condensate of metastable helium atoms.

Positron emitters are embedded in clouds of dust grains produced by supernova. This project will explore the transport of positrons in dust grains using Monte-Carlo techniques to improve our understanding of positron transport in an astrophysically relevant setting.
