Physics of extreme brightness temperatures in radioastronomical sources. Pulsars and some quasars are so very bright that the conventional explanation for radioastronomical emission from other sources either does not apply to them, or presents unsolved problems. We see (in radio waves) these sources through the interstellar medium which acts like a wrinkled pane of glass in distorting the image. New scientific ideas and methodologies are proposed here and will be explored in the project, with th ....Physics of extreme brightness temperatures in radioastronomical sources.

We see (in radio waves) these sources through the interstellar medium which acts like a wrinkled pane of glass in distorting the image. New scientific ideas and methodologies are proposed here and will be explored in the project, with the objective to understand these sources and to extract information on their propreties and those of the interstellar medium.

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.

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.

Two-electron atomic photoionization in superstrong electromagnetic field. Correlation, or entanglement, of electrons in matter governs many important phenomena in nature, such as chemical reactions, superconductivity and ferromagnetism. However, it is the many-electron processes in atoms which allow the study of electron correlations most clearly. In this project we will investigate such a process of two-electron atomic photoionization by an intense laser pulse. We will combine advanced theoret ....Two-electron atomic photoionization in superstrong electromagnetic field. Correlation, or entanglement, of electrons in matter governs many important phenomena in nature, such as chemical reactions, superconductivity and ferromagnetism. However, it is the many-electron processes in atoms which allow the study of electron correlations most clearly. In this project we will investigate such a process of two-electron atomic photoionization by an intense laser pulse. We will combine advanced theoretical and experimental tools with the aim of understanding how the electron correlation interplays with the
superstrong electromagnetic field. This will provide insight into fundamental processes of interaction of intense laser pulses with matter which are important in a wide range of applications.

Topological order and anyons: quantum engineering of emergent physics. Australia is recognized as one of the world leaders in the area of quantum information and computation. As a frontier technology with tremendous potential but engineering challenges it is vital we expand our theoretical landscape to better steer experimental development.

Australia is recognized as one of the world leaders in the area of quantum information and computation. As a frontier technology with tremendous potential but engineering challenges it is vital we expand our theoretical landscape to better steer experimental development. A promising new paradigm is topological quantum computation which uses particles with exotic statistics called anyons that do not exist naturally in three dimensions but can be engineered to emerge in two dimensional spin lattices. Our bottom up research program would help place Australia at the forefront of these ideas. As a field which combines tools from mathematics, computer science, and physics this project will provide world class training to young researchers.Read moreRead less
Atomic Ionization on the Attosecond Time Scale. Electrons emit light, carry electric current, and bind atoms together to form molecules. Insight into their atomic-scale motion is the key to understanding the functioning of biological systems, developing efficient sources of x-ray light, and speeding up electronics. Capturing this electron motion requires attosecond (one quintillionth of a second) time resolution. Our research aims to understand and accurately model fundamental atomic processes ....Atomic Ionization on the Attosecond Time Scale.

Long range interactions of atoms. Atomic physics is often described as both a basic and enabling discipline and the present project on long range atomic interactions fits within both of those categories. The results of the project will lead to a more thorough understanding of the details of long range atom-atom interactions. This will lead to Australian expertise making a significant contribution in a number of cutting edge areas in atomic and molecular physics.
Application of variational methods in atomic and molecular physics. Atmoic physics is both a basic an enabling science and this project will improve fundamental knowledge about the interactions of electrons and positrons with atoms and molecules. Research will be directly relevant to the activities of the National Positron Beam-Line (located at the Australian National University) which is directed to break-through research in matter-antimatter interactions and materials characterisation.

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.

Atomic tests of unification theories. Although the standard model of particle physics has withstood decades of intensive experimental tests, it is widely believed to be merely a low-energy manifestation of a "true" theory that unifies the four forces of nature. While some searches for new physics beyond the standard model are performed at high-energy particle accelerators, a very sensitive probe can be done at low energies in atomic and molecular measurements of weak interaction effects. This pr ....Atomic tests of unification theories.
