Life is swirl in flatland: two dimensional turbulence in a superfluid. The project will create two-dimensional turbulence in a superfluid gas of atoms in order to observe the predicted, but counter-intuitive, growth of ordered structure out of chaotic motion. The observation of such behaviour would support its mechanism as the explanation for phenomena such as giant eddies in ocean currents and the Great Red Spot of Jupiter.

These states host a variety of fascinating novel phenomena, which can be exploited for ultra-sensitive interferometry and topological quantum computing. The project will develop a complete description of these phases and design new quantum devices that utilise their properties. The fundamental significance of the project is in bringing together ideas from the diverse fields of atomic and molecular physics, condensed matter, quantum information, and topology and its direct relevance to the development of a new generation of quantum devices.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.

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

Summary
Development and application of super-sensitive spinning quantum sensors. 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.

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

New technology developed by Australia, Sweden and the United States will be applied to major questions about the application of relativistic quantum mechanics to atomic structure and dynamics and spectroscopy, especially including critical issues in quantum electro-dynamics for atomic physics and applications. Discrepancies in quantum electro-dynamics have dominated international debate for decades, with claimed explanations annually failing to reveal the cause. Also a pattern of discrepancies has been seen at X-ray energies in first row metal atoms, with a similar sign and magnitude. A combined experimental an theoretical investigation will aim to reveal new light on these anomalies and serve to develop our understanding of the universe.Read moreRead less
