Using high-resolution lasers to test quantum electrodynamics. High-precision laser-based measurements of atomic and molecular structure are benchmarks for our fundamental understanding of matter. This project will undertake state-of-the-art experiments on atomic helium, to test and challenge current theoretical predictions of fundamental quantum-electrodynamic properties for helium and for more complex atoms.
Building Schrodinger's cat: large-scale entanglement of trapped ions. Where does the microscopic quantum world leave off and the normal world begin? The project will expand the boundaries of the quantum realm by building the largest quantum objects ever assembled and put them to work in computing and cryptography. These quantum devices will help Australia lead the race for future information technologies.
Time-space resolved photoelectron emission to control molecular processes. This project aims to resolve simultaneously the timing and space localisation of photoelectron emission from atoms and molecules as a means for targeted breaking of molecular bonds. Existing techniques determine the timing and spatial characteristics of photoemission independently. The simultaneous time-space resolution will allow for the precise manipulation of photoelectrons by a sequence of phase-stabilised laser pulse ....Time-space resolved photoelectron emission to control molecular processes. This project aims to resolve simultaneously the timing and space localisation of photoelectron emission from atoms and molecules as a means for targeted breaking of molecular bonds. Existing techniques determine the timing and spatial characteristics of photoemission independently. The simultaneous time-space resolution will allow for the precise manipulation of photoelectrons by a sequence of phase-stabilised laser pulses, a technique known as coherent control. The benefit of this project will be the coherently controlled breaking of molecular bonds in oxide, carbonyl and hydrocarbon molecules. The outcome will be a significant step forward in driving complex photochemical reactions in industry.Read moreRead less

X-ray sources underpin key diagnostic techniques in materials science, advancing applications from structural engineering through to ore processing and energy storage. However, the limited brightness of present-day laboratory x-ray sources restricts the utility and range of these diagnostic techniques. This research intends to use intense lasers to create microscopic plasmas and drive high harmonic generation. The high harmonic generation process is already used to create laser-like ultraviolet light. By optimising the characteristics of the plasma medium, the project aims to extend bright high harmonic generation to the x-ray regime.Read moreRead less
