Overview

The fast development of high power laser technology over the past two decades has allowed to explore new regimes of laser-matter interaction under extreme conditions. Although a number of proof-ofprinciple experiments has been carried out, showing promising results in terms of societal applications with such compact approaches, laser-based secondary radiation sources (ions, electrons, X-rays) are still notfully mature for their application in medicine or industry, mainly due to difficulties in operating at high repetition-rate which, on the contrary, is of paramount importance for ensuring the average fluxes required by the applications.

Although currently available cutting-edge laser technologies can operate simultaneously at high peak power (TW to PW) and high repetition-rate (10 Hz to 1 kHz), the development of suitable target delivery systems and plasma diagnostics requires a considerable effort in order to demonstrate robust and accurate solutions to be used for multidisciplinary applications. Several challenges related to the harsh
laser-plasma environment (such as ultrahigh radiation dose rate, ultrahigh electromagnetic pulses, plasma
debris), as well as shot-to-shot source instabilities, impose strict limitations in terms of usable targetry
and diagnostics.
The PhD candidate will study and select a number of suitable targetry and diagnostic solutions for the
generation and characterization of laser-plasma sources (particles and XUV radiation) at high repetitionrate (30J/30fs/10Hz and/or 30mJ/15fs/1kHz). The work will include feasibility studies for further development of available technical solutions, as well as experimental tests at domestic (TARANIS, RAL)
and international (Extreme Light Infrastructure) high power laser facilities, thus being part of a large
international research team. Handling of large data acquisition systems and optimization of data analysis
procedures will also be carried out by the student.

Course content

Research Information

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
Atomistic Simulation (PhD/MPhil)

Atomistic Simulation is the development and use of theoretical and computational methods to study structural, dynamical, and optical properties of molecules, liquids, solids and plasmas at the nanoscale. Computational experiments are used to interpret existing experimental data and to predict phenomena yet unobserved.

You’ll study problems at the interfaces between condensed matter physics, materials science, chemistry, biology, and engineering. You’ll interact with laboratory-based colleagues at Queen's and internationally, addressing fundamental and/or practical questions, and you will develop and program novel simulation methodologies to model for instance, electronic excitations, optical properties of materials, and the interaction between electric currents, heat and light.

Themes that are presently studied in the ASC include: non-linear optics in 2D materials, plasmonics, laser and ion-matter interactions, radiation damage in biology and nuclear materials, conduction in nanowires, aqueous Interfaces, nucleation, and crystallisation. Tools include time-dependent density-functional theory, many-body perturbation theory, classical molecular dynamics, Monte Carlo simulations and machine learning.

Research Themes
Centre for Nanostructured Media (PhD/MPhil)

Human history is defined by the materials we use to underpin our technology: stone, bronze, iron, silicon. As a PhD student in the Centre for Nanostructured Media, 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, at the same time, become proficient in techniques for materials growth, patterning and characterisation that are highly valued in high-tech companies and commercial research institutions, as well as in academic research settings. Our laboratories 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
Plasma Physics (PhD/MPhil)

Your research will involve identifying, and responding to, major contemporary issues within ionised matter physics, with major activities in laser- and electrically-produced plasmas, ultra-fast atomic and molecular physics and the interaction of ionising radiation and plasmas with matter, including biological systems. This research will employ local, national and international facilities, including some of the most powerful laser systems worldwide. You will also benefit from transferring your research findings into the industrial and medical sectors.

Research Themes
Theoretical Atomic, Molecular and Optical Physics (PhD/MPhil)

You’ll contribute to a body of work with recent major developments including strong field laser interactions with atoms and molecules, quantum information processing, quantum optics, and quantum thermodynamics, antimatter interactions with atoms and molecules, electron scattering by very complex targets such as the iron peak elements, and by Rydberg atoms, quantum many-body physics, ultra-cold atomic systems, and simulation of their features, and foundations of quantum mechanics.

Postgraduate research programmes within CNM provide experience and training in state-of-the art academic research: many of our research strands are world-leading, as evidenced by performance in REF2014. In addition, most of our postgraduate researchers are exposed to functional materials and photonics in major multinational companies.

Assessment

Assessment processes for the Research Degree differ from taught degrees. Students will be expected to present drafts of their work at regular intervals to their supervisor who will provide written and oral feedback; a formal assessment process takes place annually.

This Annual Progress Review requires students to present their work in writing and orally to a panel of academics from within the School. Successful completion of this process will allow students to register for the next academic year.

The final assessment of the doctoral degree is both oral and written. Students will submit their thesis to an internal and external examining team who will review the written thesis before inviting the student to orally defend their work at a Viva Voce.

Feedback

Supervisors will offer feedback on draft work at regular intervals throughout the period of registration on the degree.

Facilities
The School has invested over £12 million in new world-class student and staff facilities since 2014. A new teaching centre opened in 2016 which includes experimental physics laboratories, two large computer rooms and plenty of student study and interaction space.
