New physics with strongly correlated and spin-orbit-coupled electrons. This project aims to identify new physics in quantum magnets and emergent phenomena in solids where the electrons are strongly coupled and intertwined in a complex manner. As a consequence, quantum effects are dramatically enhanced and, in certain situations, force the electrons to split into different exotic particles.

This project aims to identify new physics in quantum magnets and emergent phenomena in solids where the electrons are strongly coupled and intertwined in a complex manner. As a consequence, quantum effects are dramatically enhanced and, in certain situations, force the electrons to split into different exotic particles. This project expects to identify suitable physical systems, candidate materials and appropriate conditions required for the experimental observation of this phenomena with neutron scattering methods. The advanced materials and exotic particles identified in this project will inform the development of next generation technologies, becoming the quantum bits in future quantum computers.Read moreRead less

Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic d ....Dopant engineering of diamond for quantum sensing technologies. Doped diamonds are central to a growing range of quantum-sensing technologies for future industries, including medical and defence. These diamonds must be doped with both an electron donors and active 'quantum-defects' to operate. Within existing devices, the electronic donors also create parasitic magnetic noise, due to their magnetic-spin properties. In this project we aim to investigate the growth of diamond with new electronic donors, aiming for spin-free and thus noise-free dopant properties. This should provide significant benefits to defence capability, through enhanced magnetic anomaly detection in naval environments, and health outcomes, through neural sensing of brain signals at room temperature.Read moreRead less
Magnonics with skyrmions. Skyrmions – nanoscale topologically protected spin textures, are considered as ideal candidates for encoding and transmitting bits of information. This burgeoning research field, however, suffers from the same limitations of all spintronic concepts – the high currents needed to move skyrmions. Magnonics is yet another emerging approach, which main aim is to investigate the behaviour of spin waves in magnetic nanostructures.

Skyrmions – nanoscale topologically protected spin textures, are considered as ideal candidates for encoding and transmitting bits of information. This burgeoning research field, however, suffers from the same limitations of all spintronic concepts – the high currents needed to move skyrmions. Magnonics is yet another emerging approach, which main aim is to investigate the behaviour of spin waves in magnetic nanostructures. In essence, spin waves are a propagating re-ordering of the magnetisation and therefore use the least amount of power, making them perfect for driving skyrmions. This project fuses skyrmions with magnonics. The central goal is the formulation of model for the magnon assisted manipulation of skyrmions and their lattices.Read moreRead less

We have discovered a method to make silicon highly enriched in the desirable spin-zero isotope using readily available ion implantation tools. This “semiconductor vacuum” is essential for building future quantum computer devices using the quantum spin of millions of implanted atoms with revolutionary capabilities. We have demonstrated long-lived implanted donor atom quantum states in prototype material, made possible by the depletion of background spins in natural silicon and now aim to push the enrichment to greater extremes. We will integrate the extreme material into functional devices that use electrically detected electron spin resonance to probe exceptionally durable quantum states and open a near-term pathway to large-scale devices.Read moreRead less
