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
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.
Cold positron interactions with ultracold rubidium atoms. Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project aims to further study how antimatter and matter interact by providing the first comprehensive experimental results for the interaction of positrons (the electron anti-particle) with trapped rubidium atoms in an innovative combination of two cutting-edge ....Cold positron interactions with ultracold rubidium atoms. Antiparticles and antimatter have progressed from theory and science fiction to become an important and exciting area of pure and applied science. This fundamental atomic physics project aims to further study how antimatter and matter interact by providing the first comprehensive experimental results for the interaction of positrons (the electron anti-particle) with trapped rubidium atoms in an innovative combination of two cutting-edge atomic physics techniques. It aims to provide measurements of many fundamental interaction quantities and for collisions between matter and antimatter. This will look to test the latest quantum theoretical approaches and further our understanding of the uses of antimatter in medical and materials science.Read moreRead less
