Violation of the fundamental symmetries is predicted by unification theories of elementary particles. The aim of this project is to propose new enhanced effects of parity, time reversal and Lorentz invariance violations and perform their calculations needed to test unification theories in atomic and nuclear phenomena. By-products of this project include development of high precision computer codes for atomic calculations and theory of processes involving atoms and nuclei in chaotic excited states. These codes and theory are expected to have numerous applications (e.g. search for Dark Matter and atomic spectra of superheavy elements, atomic clocks and electron and photon processes).

The dominance of matter over antimatter in the Universe is one of the most intriguing questions of today’s science. Researchers at the European Organisation for Nuclear Research (CERN) are addressing this question by creating antihydrogen and studying its properties, including the gravitational behaviour. By trapping and cooling antihydrogen positive ions, ultra-cold antihydrogen atoms can be created and used in free fall experiments at CERN. The convergent close-coupling method and threshold theory will be used to provide the necessary theoretical guidance for the experimental antihydrogen positive ion formation via low-energy positronium-antiproton and positronium-antihydrogen collisions.Read moreRead less

This project aims to propose and assist in the development of novel approaches, based on atomic, molecular and optical technologies, to detect dark matter in the laboratory, and thereby establish the identity and microscopic properties of dark matter. The origin and nature of dark matter remains one of the most important outstanding problems in contemporary science. The intended outcome of this project is that the use of our novel methods will enable us to search for forms of dark matter that have remained largely unprobed to date. This in turn is expected to open up new opportunities in the global hunt for dark matter that should improve our chances of finally discovering the nature and properties of dark matter.Read moreRead less

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

The interaction of low-temperature plasma electrons with liquids has served as a reducing agent in various technological applications in water treatment, agriculture, biofuels and medicine. Predictive control of the plasma-liquid interface is essential to unlocking the potential of these applications, and this has been limited by the absence of the relevant non-equilibrium transport theory describing electrons at the plasma-liquid interface together with fundamental data describing electron interactions with liquids. The project will develop a state of the art presolvation electron transport model informed by world first measurements of electron cross-sections for radicals and liquids and apply it to model plasma electrochemistry processes.Read moreRead less

This project will develop next-generation focused ion beam microscopy and nanofabrication using a novel cold ion source based on photoionisation of a laser-cooled atom beam. The low temperature and complex internal state structure of the constituent atoms combine to allow generation of ions with unprecedented brightness and resolution. We will use three unique and innovative ideas: field ionisation of atoms in so-called 'exceptional' states to reduce chromatic aberration; electron-ion correlations to enhance control of the ions at the nanoscale; and atom-atom interactions to isolate and manipulate individual ions. The new technology will enable advances in semiconductor nanofabrication and material characterisation.Read moreRead less

This project aims to use physical rotation of diamonds on timescales faster than quantum decoherence to set new detection limits for precision quantum sensing of electric and magnetic fields. This potentially allows us to see for the first time how the Coriolis force acts on current flowing in a frame rotating 700,000,000 times faster than the earth. The project's expected outcomes are electro-magnetic sensors with unprecedented sensitivity that could find application in areas ranging from detecting household wiring to locating magnetic anomalies for defence. These outcomes should fill a blind spot of quantum magnetometry, have commercial impact and expand our knowledge of quantum physics in the rotating frame.Read moreRead less
