Overview
Applications are invited for a PhD studentship in the Department of Mathematics. The successful candidate will have the opportunity to work on Entanglement Measures, with a focus on a recently proposed measured known as Symmetry Resolved Entanglement Entropy.
The study of entanglement measures in integrable quantum field theory has been a very active field of research for nearly 20 years.
Over this period, many intricate properties of entanglement have been understood and new measures of entanglement developed.
Among the latter, the symmetry resolved entanglement entropies (SREEs) are the most recent addition. Initially proposed in the work of Goldstein and Sela they have recently become very widely studied in the context of 1+1D quantum field theories both at and away from criticality, including several recent contributions involving the first supervisor.
These studies are partly motivated by the fact that SREEs can be measured experimentally. In this project, we will study these quantities further, especially in the context of integrable quantum field theory employing the branch point twist field (BPTFs) approach.
The proposed research will afford the successful applicant a chance to work with a leading expert in the field and to be introduced to a mathematically and physically sophisticated, highly specialised, and rapidly developing area of theoretical physics.
The work has connections to integrable models in quantum field theory, and it this context, may be also extended to consider such models in out-of-equilibrium situations, connecting to another area of much current interest.
Successful completion of the Thesis will place the applicant in a good position to develop an independent research career and to access positions at prominent research institutions throughout the world. It will train the applicant in leading mathematical techniques within theoretical physics.
It will lead to new results which will have academic impact within communities working actively on the study of entanglement measures, be it those interested in the entanglement of critical systems in 1+1 dimensions, those interested in the application and interpretation of these results in a quantum information setting or those interested in recovering such results from AdS/CFT computations.
Eligibility and requirements
The candidate should have an upper second-class honours BSc degree in Physics and a specialisation (ideally at MSc level) in Theoretical Physics. They should be proficient in written and spoken English and demonstrate aptitude for original research.
The candidate should have a strong background in Theoretical Physics and Applied Mathematics. They should be able to carry out complex calculations, involving real and complex analysis techniques. They should be able to carry out their work precisely and methodically.
It is highly recommended that they are also conversant with some programming languages (i.e. Phython, C++) and algebraic manipulation packages (i.e. Mathematica, MatLab). Finally, they should be able to communicate in English both in written and oral form, to a high standard.
A doctoral candidate is expected to meet the following pre-requisites for their PhD:
- Demonstrate a sound knowledge of their research area
- Achieve and demonstrate significant depth in at least a few chosen sub-areas relevant to their primary research area
- Demonstrate the ability to conduct independent research, including a critical assessment of their own and others’ research
Having published high-quality papers in reputable peer-reviewed conferences and journals will be an advantage for the candidate.
Funding
The studentship is for 3 years and will provide full coverage of tuition fees (Home and Overseas) and an annual tax-free stipend of £12,000.
Each student would also have the opportunity to earn around £2.2K pa on an average (max. is around £4.3K pa) through a teaching assistantship. We shall prioritise these scholarship holders while allocating the teaching assistantships.
How to apply
If you are interested in applying, you are encouraged to email initial informal enquiries to Dr Olalla Castro-Alvaredo.
Visit our Mathematics research degrees web page for further information on making a formal application.
When submitting your application, enter the title “Symmetry Resolved Entanglement in Quantum Field Theory” and you will automatically be considered for this studentship.
You do not need to submit a proposal as part of your application as the project has already been outlined.
The online application can be found in the ‘How to apply section’ in the web link above and should include the following supporting documents:
- Copies of Degree Certificates and Transcripts in official English translation - original will be requested before an offer is made.
- Official work e-mail addresses (not private ones) for two referees (one of which must be an academic).
- Proof of English Language proficiency (minimum average score of 6.5 IELTS, with a minimum of 6.0 in each of the four components) if English is not your first language.
- Passport.
The outcome of the selection process should be announced by the end of June. The successful candidate will formally start their doctorate either in July or in October 2022.
