In and beyond the standard model of particle physics. The standard model of particle physics was developed twenty years ago, and it has been remarkably successful at describing the experiments carried out since then. Now, however there is evidence that there is physics beyond the standard model, and new and planned experiments will make the details of this new physics clearer in the lifetime of this grant. We will study a wide variety of systems, from the foundations of quantum mechanics to ....In and beyond the standard model of particle physics. The standard model of particle physics was developed twenty years ago, and it has been remarkably successful at describing the experiments carried out since then. Now, however there is evidence that there is physics beyond the standard model, and new and planned experiments will make the details of this new physics clearer in the lifetime of this grant. We will study a wide variety of systems, from the foundations of quantum mechanics to extra dimensions of space-time and much between and will find guides to the nature of the new physics.

Neutrino physics: a window on physics beyond the standard model. The recent observation of neutrino oscillations demonstrates that neutrinos have a non-vanishing mass. This is not accomodated in our "standard model" of particle physics, which must therefore be extended. Clues has to how this extension is to be made are to be found in the pattern of masses and mixings, and in possible new interactions involving neutrinos. These clues will be examined to find a viable set of extensions of th ....Neutrino physics: a window on physics beyond the standard model.

Does High Temperature Superconductivity Reside in Plane or Charge Reservoir (CR) Oxygen, in YBa2Cu3O7 (YBC)? One of the outstanding problems in contemporary solid state physics concerns the mechanism of high temperature superconductivity (HTS). In particular, what binds charges that normally repel one another, into (Cooper) pairs? Closely related to this question is where the superconductivity resides in the material. We aim to answer the latter question in the much studied prototypical HTS YBa2 ....Does High Temperature Superconductivity Reside in Plane or Charge Reservoir (CR) Oxygen, in YBa2Cu3O7 (YBC)? One of the outstanding problems in contemporary solid state physics concerns the mechanism of high temperature superconductivity (HTS). In particular, what binds charges that normally repel one another, into (Cooper) pairs? Closely related to this question is where the superconductivity resides in the material. We aim to answer the latter question in the much studied prototypical HTS YBa2Cu3O7. In doing so we expect to demonstrate that phonons, widely believed not to play a role in HTS are in fact an important component in the HTS pairing mechanism.Read moreRead less
Understanding Collisions of Cold Polar Molecules. This project is in a high impact research field and therefore has several immediate and substantial national benefits. First, this project will directly raise the quality of Australian science in ultracold atomic physics, cold polar molecules physics, and quantum chemistry. Second, it will constitute high impact research from an Australian institute which will raise the recognition of the high quality Australian science. Third, it will further ....Understanding Collisions of Cold Polar Molecules. This project is in a high impact research field and therefore has several immediate and substantial national benefits.

We will exploit the quantum nature of multiple particle quantum states of atoms and photons including entangled light and Bose-Einstein condensates. The Centre will focus on fundamental research, but our long term goal is to underpin and develop the next generation quantum technology. We aim to build a quantum toolbox to enable applications such as the transfer and storage of information for photonics, and precision quantum control of atoms for enhanced atom interferometry.Read moreRead less
Decoherence in quantum computing and quantum electromechanical systems. Australia is one of the world leaders in fundamental studies and implementation of quantum computing and quantum electromechanical systems.

Australia is one of the world leaders in fundamental studies and implementation of quantum computing and quantum electromechanical systems. By developing a framework to quantify and control noise due to decoherence in such systems, this research will facilitate progress in the development and understanding of quantum computing and quantum electromechanical devices. The project will also significantly strengthen the general representation of research on decoherence, a field of crucial importance to many areas of theoretical and experimental physics, in Australia. Funding of this project will enable Australia to further expand its leading position in cutting-edge science and next-generation technology.
