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.

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.

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.

A clear understanding of positron binding and the underlying mechanisms will open a new era in low-energy positron-atom/molecular physics, leading the way for breakthrough sciences. For instance, a positron bound state should enhance the annihilation rate between the positron and target valence electron. Positron annihilation, to produce two gamma rays, is a key process in both materials research (e.g. as already heavily employed in defect detection) and bio-medical treatments (e.g. the Positron Emission Tomography, or PET).Read moreRead less
