This project aims to tackle a great challenge of atomic-scale characterisation: quantitative structure determination. Powerful new electron microscopes offer a window into the atomic world, but complex electron multiple scattering has limited reliable structure determination to ultrathin materials. This project expects to overcome this barrier. Anticipated outcomes include methods that use the latest detector technology to determine structure and interatomic bonding in much thicker nanostructures than hitherto possible. This should benefit academic and industrial researchers by giving them new tools to understand and design high-performance materials for applications ranging from catalysis to energy storage to next-generation electronics.Read moreRead less

This project aims to use innovative quantum sensing technologies to investigate the novel emerging field of two-dimensional magnetism; imaging both static and dynamic forms of 2D magnetism. This project expects to generate new knowledge about magnetic van der Waals materials and their potential application to ultra-thin electronic and spintronic devices. Expected outcomes of this project are a deeper understanding of the formation and modulation of magnetic order in 2D, new fabrication methods for deliberate domain wall formation, production of near-zero energy gap spin-waves, and new encapsulation methods for ultra-stable 2D materials. This should provide significant benefits towards fundamental physics and future device engineering. Read moreRead less
Hot Topic: Quantum Design of Phononic Heat Filters. 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.

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
Braiding Dynamics of Majorana Modes. The project aims to investigate Majorana modes, exotic quantum particles which can be found in the new material class of Topological Superconductivity. In particular, they can be utilised to construct fault-tolerant quantum bits. Quantum logic gates are enabled by moving these Majorana modes around each other, i.e., by braiding them, leading to an error-free quantum performance. This project will deliver cutting-edge simulations to analyse the braiding proces ....Braiding Dynamics of Majorana Modes.

Quantum logic gates are enabled by moving these Majorana modes around each other, i.e., by braiding them, leading to an error-free quantum performance. This project will deliver cutting-edge simulations to analyse the braiding process in condensed matter systems and benchmark how these fault-tolerant quantum bits operate under real-world conditions. By providing the theory for advanced structures and devices, this project will inform experiments and pave the way for future technology based on topological phenomena.Read moreRead less
Unlocking the potential of magnetic 2D materials with quantum microscopy. This project aims to create a universal, high-throughput platform to characterise magnetic 2D materials, by exploiting recently developed quantum diamond microscopy. It will enable the measurement of hitherto inaccessible magnetic properties of individual 2D microsheets, the imaging of device-relevant phenomena such as domain wall dynamics and skyrmionics, and the systematic screening of newly synthesised materials.

This project aims to create a universal, high-throughput platform to characterise magnetic 2D materials, by exploiting recently developed quantum diamond microscopy. It will enable the measurement of hitherto inaccessible magnetic properties of individual 2D microsheets, the imaging of device-relevant phenomena such as domain wall dynamics and skyrmionics, and the systematic screening of newly synthesised materials. Anticipated outcomes include crucial new insights into 2D magnetism and the discovery of magnetic 2D materials compatible with real-world conditions. This should accelerate the development of future energy-efficient and flexible electronics and memory technologies, where magnetic 2D materials are expected to play a key role.

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
