This project aims to create a complete list of possible topological phonons in time-reversal-invariant systems via symmetry analysis, to determine ideal topological phononic materials, and to study topological phonon-related properties and possible applications. The significant outcomes of this project will be the generation of new knowledge that will help conclude the search for novel topological phonons and the prediction of novel topological phononic materials based on the complete classification list of topological phonons. The outcomes of this project should unlock the physics of the exotic topological phonons and lay a solid foundation for applying topological phononic materials based on their unprecedented properties.Read moreRead less

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

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
