Numerical modelling of the solar atmosphere. This project will develop a complete and realistic model of the magnetic solar activity using computer simulations of the interconnected solar interior and atmosphere. The results of this project will provide a deeper insight into the physical processes behind solar activity phenomena and will help in the development of methods of solar activity prediction.
Atomic scale ion microscopy via laser cooling and correlated imaging. This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'excep ....Atomic scale ion microscopy via laser cooling and correlated imaging. This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'exceptional' states to reduce chromatic aberration; electron-ion correlations to enhance control of the ions at the nanoscale; and atom-atom interactions to isolate and manipulate individual ions. The new technology will enable advances in semiconductor nanofabrication and material characterisation.Read moreRead less
Fundamental physics in distant galaxies. The fundamental constants of Nature are assumed to characterise physics in our entire Universe, but are they really the same everywhere and throughout its entire 14 billion year history? This project will answer this question with the first large-scale, purpose-built observational programme on one of the world's biggest and best telescopes.
Novel advances in sub-nanometer imaging. After two decades of research the first wave of applications in nanotechnology and nanobiology is breaking. Immediately key to further progress in both areas is the ability to characterise the structure of such systems and also their evolution on very short time scales. This research project places Australia at the forefront in this endeavour.
Shape-Shifting Molecules: Photoisomerization Action Spectroscopy. This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field.

This project aims to examine molecules that change shape in response to light in order to gain insight into the biological processes they control. Many biological systems, including the human visual apparatus and bacterial photosynthesis, depend on molecules that change shape in response to light. The project plans to probe shape-shifting molecules with laser light while they are propelled through gas by an electric field. Light-induced changes in molecular shape produce detectable variations in drift speed. The ensuing knowledge would help calibrate computational approaches for predicting molecular function. It would also establish foundations for understanding essential biological molecules, including retinals, carotenes and peptides, and for developing new light-activated molecular motors and switches.Read moreRead less

This project aims to use physical rotation of diamonds on timescales faster than quantum decoherence to set new detection limits for precision quantum sensing of electric and magnetic fields. This potentially allows us to see for the first time how the Coriolis force acts on current flowing in a frame rotating 700,000,000 times faster than the earth. The project's expected outcomes are electro-magnetic sensors with unprecedented sensitivity that could find application in areas ranging from detecting household wiring to locating magnetic anomalies for defence. These outcomes should fill a blind spot of quantum magnetometry, have commercial impact and expand our knowledge of quantum physics in the rotating frame.Read moreRead less
