Heat management is critical to many technologies for sustainable energy, electronics, protective equipment and energy-efficient buildings. The phonon is the quantum particle representing a travelling vibration and is responsible for the transmission of heat in solids. This project will study the new mechanisms for phonon transport in solids modified with embedded nanoparticles, which operate as phononic filters. Neutron spectroscopy provides a tool to measure the phonon density of states which is critical for developing a mathematical model of thermal boundary resistance. This is expected to identify mechanisms for ultra-low thermal conductivity leading to potential applications in thermoelectric generators and heat-resistant materials.Read moreRead less

Ultrafast time resolved optical spectroscopy for advanced multifunctional materials: Time resolved spectroscopy is among the hottest emerging fields in condensed matter physics and offers a new perspective into the complex physics of multifunctional materials like multiferroics or unconventional superconductors. At present, the underlying physics of these novel complex materials is not fully understood and new experimental approaches such as the proposed time-resolved optical spectroscopy are required. The deeper understanding of the involved phenomena would also allow for a systematic search for new, undiscovered multifunctional materials with similar but enhanced properties. This offers a huge potential for future industry in applications such as in novel sensors, information processing, and high efficiency photovoltaics.Read moreRead less

The recent discovery of topological insulators reveals the tip of the iceberg, but many theoretical hypotheses, such as the existence of the fractional Chern insulator and quantum spin liquid, remain elusive. This project aims to bridge the gap between conceptual models and real materials by using first-principles calculations. The plan is to identify and engineer topological electronic bands in experimentally feasible materials, characterise existing quantum frustrated materials and connect these materials with minimal theoretical models. This project also aims to reveal further families of topological materials and clarify their physical properties.Read moreRead less

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
