Visualizing electron dance in transition metal dichalcogenides
A world-class environment for your research degree
The School of Physics is offering a portfolio of PhD Scholarships across all its world-class research groups. These prestigious Scholarships represent a great opportunity to start your Postgraduate Research Career working with world-class academics in a supportive training and development environment. Physics at Bristol was ranked 5th for Research in the 2022 Research Excellence Framework (REF) results, and the University of Bristol is truly world-leading: 55th in the QS World University Ranking (2024) and 81st in the Times Higher Ranking (2024).
What does a Scholarship cover?
For home students, the scholarships will cover living expenses (UKRI rate), University tuition fees (see PhD Physics Study at Bristol University of Bristol), and training and support expenses. We also welcome applications from outstanding international candidates: we are able to offer a very small number of fully-funded places, but also accept students who can provide full or partial funding from other sources. If you need an offer letter to apply for a competitive scholarship, please get in contact with us well before any deadlines.
Research Project
Let’s start from use dancing picture to intuitively understand macroscopic quantum states. In the correlated electronic systems, every particle dance by itself, and they all dance in the same way that forms a long-range order. In a fermion superfluid, fermions dance around in pairs and each pair is doing the same dance. While a topological order is described by a global dance, where every particle is dancing with every other particle in a very organized way where the particles follow a set of local dancing rules, form a global dancing pattern, and create a pattern of long-range entanglement.
The intertwined dance of fermions and topology can lead to intrinsic topological superconductivity (ITS). Intrinsic topological superconductivity is an unprecedented quantum state that stands at the frontier of modern quantum matter. ITS promise both cutting-edge science and revolutionary quantum technology. Its key signatures include the existence of odd-parity electron pairing, superconductive topological surface bands, and, when time-reversal symmetry (TRS) is broken, persistent chiral supercurrents with speed flowing along every surface.
You will exploit these exciting opportunities by using direct atomic-scale visualization of ITS fingerprints. You will focus on candidate materials 4Hb-TaS2 and 2M-WS2, among others. Using ultralow temperature and high magnetic field STM at the Universities of Oxford and Bristol, you will pursue three scientific objectives. (1) Demonstrate the presence of odd-parity superconducting pairing. (2) Momentum-space visualization of the topological surface band. (3) Detect a flowing chiral surface supercurrent when TRS is broken. Your ultimate goal will be to confirm the presence and explore the unprecedented physics of ITS, distinct revelation of which ITS phenomena occur in nature, and eventual identification of the ITS that are most ideal for quantum technology.
The Bristol Physics Graduate Research Community
If successful, you will become a member of the Physics Graduate School, a vibrant and diverse community of 200-plus research students from a wide range of countries and backgrounds. The Graduate School:
· runs a comprehensive induction programme to get you off to the best possible start in your research, and a rolling programme of targeted skills training on writing, presenting, project-planning, etc.
· operates a “one-stop shop” approach to help you navigate through the University procedures
· organises meetings for postgraduate opportunities, and support in transitioning to post-PhD careers
· connects you to the wider University, including the Bristol Doctoral College, www.bristol.ac.uk/doctoral-college/.
How do I apply?
You will need (1) a CV, (2) a Personal Statement, which is a one- to two-page document introducing yourself and outlining your motivation for PhD research, and (3) a transcript of any qualifying degrees (completed and/or underway).
Please note that a research statement is not a requirement from the School of Physics, however as it is a system requirement you are encouraged to specify a research theme and a list of your preferred academic supervisors.
Please contact the academics within the School of Physics research areas for information.
Applicants will be assessed on merit, and interviews will be held for shortlisted applicants.
You need to apply through the University of Bristol application system at http://www.bristol.ac.uk/study/postgraduate/apply/. Please select Physics PhD or Physics MSc by Research on the Programme Choice page. The School of Physics supports Diversity and Equality, and we invite all eligible candidates to apply. We encourage applications from under-represented groups. We hold a Bronze Athena Swan award and a Physics Juno Champion award.
Please specify “Bristol Physics Research Scholarships” on the application form as your source of potential funding. Early application is encouraged. The closing date for applications to this call is 15 January 2025.
What are the candidate requirements?
A first degree in physics or a related subject, normally at a level equivalent to at least UK upper second-class honours, or a relevant postgraduate master’s qualification. Please see Applying from your country International students University of Bristol on the International Office website.
English language requirements
