Operator algebras as models for dynamics and geometry. Operator algebra is the mathematical theory which describes quantum physics and predicts how quantum systems will behave. Through this project, the researcher's recent discoveries in operator algebra will give us new insight into the dynamics and geometry - that is, the behaviour and shape - of the quantum world.
Perovskite-silicon tandem solar cells: a pathway to 30 per cent efficiency. This project aims to develop a new type of solar cell that is much more efficient than today’s commercial silicon solar cells. Increasing cell efficiency is one of the most effective ways to reduce the cost of solar electricity, but silicon cells are approaching practical and theoretical limits. This project expects to boost the efficiency of silicon solar cells by adding a low-cost solar cell on top to create a tandem d ....Perovskite-silicon tandem solar cells: a pathway to 30 per cent efficiency. This project aims to develop a new type of solar cell that is much more efficient than today’s commercial silicon solar cells. Increasing cell efficiency is one of the most effective ways to reduce the cost of solar electricity, but silicon cells are approaching practical and theoretical limits. This project expects to boost the efficiency of silicon solar cells by adding a low-cost solar cell on top to create a tandem device. The expected outcome is a solar cell that can convert more than 30 per cent of incident sunlight into electricity, compared to 20-25 per cent for current cells. Developing cheap, high efficiency solar cells should further reduce the cost of solar electricity, and accelerate the uptake of clean energy.Read moreRead less

Harmonic analysis in rough contexts. Harmonic analysis is a set of mathematical techniques aimed at decomposing complex signals into simple pieces in a way that is reminiscent of the decomposition of sounds into harmonics. It is highly efficient in analysing signals in homogeneous media such as wave propagation through the air that underpins wireless communication technology. However, wave propagation through inhomogeneous media, such as the human body in medical imaging or the Earth in geophysi ....Harmonic analysis in rough contexts. Harmonic analysis is a set of mathematical techniques aimed at decomposing complex signals into simple pieces in a way that is reminiscent of the decomposition of sounds into harmonics. It is highly efficient in analysing signals in homogeneous media such as wave propagation through the air that underpins wireless communication technology. However, wave propagation through inhomogeneous media, such as the human body in medical imaging or the Earth in geophysical imaging, is much harder to model. Phenomena with random components, as considered in finance for instance, are also problematic. This project is an important part of an intense international research effort to develop harmonic analysis in such rough contexts.Read moreRead less
Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in sit ....Advanced materials for space propulsion: satellites and cubesats. Poorly controlled interactions between plasmas and surfaces often mean loss of process efficiency and surface degradation over time. For Hall thrusters, a type of engine used to move satellites in space, this means increased fuel consumption and shorter useful life. Through modelling and experiment, this project will show how intelligent selection of advanced materials and plasma parameters can minimise surface wear, enable in situ material repair to extend device lifetime, and modulate plasma properties to increase thruster efficiency for a given task. These benefits enable reliable propulsion platforms for massive communication and observation satellite networks and deep space exploration.Read moreRead less
