Overview
This project will focus on the emerging use of ultrafast pulses of laser driven ions and to initiate damage cascades in technologically and biologically relevant materials. The recent demonstration of few picosecond proton pulses generated using the Taranis laser system in the Centre for Plasma Physics provides a solid platform to advance these studies to a wide range of materials [1-3].
In an additional stand, recent observations of sub-picosecond switching of the optical properties of opto-electronic crystals will be investigated using X-ray Free Electron Lasers (XFEL) with additional funding by the Science and Technology Facilities Council (STFC). This ultrafast switching is a breakthrough observation and opens a new paradigm for the control of optical systems.
The successful applicant will work in tandem with experienced researchers in the Centre for Plasma Physics designing and implementing experiments on the Taranis laser system. New techniques will be developed to study the transient spectroscopic features of ion induced damage in condensed matter as well as working on improving the efficiency and spectral characteristics of the ultrafast ion pulses. This project will also provide exceptional grounding in cutting edge ultrafast laser technology and the opportunity to travel to major large facilities around the world (i.e. Jena and Munich in Germany and the European XFEL) with an emphasis on a results driven program. There will also be emphasis on working with cutting edge particle in cell code simulations to develop atheoretical understanding of the mechanisms underlying these processes.
Skills gained by student:
The skillsets developed as part of this project fall under two categories.
Firstly, lab-based skills. As this project will involve the use of high-power laser systems a broad range of skills essential for working safely and efficiently in a laboratory environment will be developed and honed. Communication and working with international teams of scientists and working with technical staff to develop and animate detailed ideas will form the basis for a transferable skillset that is essential for any tech-focused career. Significant emphasis will be placed on developing scientific skills suitable for XFEL science and research.
Secondly, simulation-based skills. A significant fraction of this project will be devoted to thoroughly investigating the ion acceleration process from laser matter interactions to form the theoretical framework for the associated experiments. This will develop skills in the use of high-power computing, writing proposals for accessing large clusters and the use of particle in cell codes (EPOCH and WARP-X) to simulate and model the interactions.

Research Themes
Astrophysics (PhD/MPhil)
You’ll be involved in the search for distant supernovae and where they came from; study the asteroid and comet population in the Solar system; look for planets orbiting other stars in our Galaxy; study flares and other dynamic processes in the atmosphere of the Sun. You’ll have the opportunity to spend extensive periods at world-leading research centres such as the European Southern Observatory and NASA Goddard Space Flight Center.
At Queen’s we lead major European consortia and are supported by a multi-million pounds portfolio of research grants from a range of sources, including the UK Science and Technology Facilities Council, the Royal Society, and European Union.
Research Themes
Centre for Quantum Materials and Technologies (PhD/MPhil)
Human history is defined by the materials we use to underpin our technology: stone, bronze, iron, silicon. As we enter the emerging Quantum era, this impetus on materials and their link to technologies becomes even stronger. As a PhD student in Centre for Quantum Materials Technologies, you will be playing a part in the development of materials systems which will, in some way, define our technology for the future. How can this not be exciting? You will seek to reveal the physics of material behaviour at the boundary of current global knowledge and quantum limits, at the same time, become proficient in techniques for Quantum computation, materials growth, patterning, characterisation and theoretical modelling.
These skills are highly valued in high-tech companies and commercial research institutions, as well as in academic research settings. Our laboratories and computational facilities are extremely well-equipped for international-level research and our links to other research teams throughout the world in both academia and industry are strong and you should expect to travel, should you wish to, as part of your PhD experience.
Research Themes
Centre for Light Matter Interactions (PhD/MPhil)
Your research will involve identifying, and responding to, major open problems in laser- and electrically-produced plasmas, ultra-fast atomic and molecular physics, the interaction of ionising radiation and plasmas with matter (including biological systems), the physics of antimatter interactions with atoms and molecules, and the description of strong field laser interactions with atoms and molecules.
You will address fundamental and/or practical questions related to the description of electronic excitations, optical properties of matter, and the interaction between electric currents, heat and light. Your theoretical activity will imply the development and programming of novel simulation methodologies to model such processes. Experimentally, you will employ local, national and international facilities, including some of the most powerful laser systems worldwide ,while benefiting from transferring your research findings into the industrial and medical sectors.
