MMatPhys course: Quantum Processes in Hot Plasmas

My research concentrates on the design and analysis of experiments fielded on high-power lasers and pulsed-power machines. These experiments produce, in miniature and for a very short time, extreme plasma conditions similar to those found in a variety of exotic astrophysical objects, ranging from planetary interiors to conditions found at the centre of the Sun and more highly-evolved stars. This subject is known as High Energy Density Physics.

As well as being of wide scientific interest this work is also of relevance to the study of inertial confinement fusion in which thermonuclear fusion energy is generated in the laboratory using plasmas of high energy density. Recent work, undertaken with Peter Hatfield, has used machine-learning to design inertial confinement fusion targets through the use of a genetic algorithm.

Our work on using high-power lasers to create matter from light using the two-photon Breit-Wheeler process can be found in our Nature Photonics paper and an example of media coverage can be found in this BBC news website article and on the Wikipedia page. Experiments which have attempted to demonstrate the process are currently being analysed.
