About this position
This PhD project at the University of Bristol's School of Physics focuses on studying high-temperature superconductors using advanced quantum sensors, specifically nitrogen-vacancy (NV) centres in diamond. The research aims to address key challenges in understanding unconventional and conventional superconductors, such as hydrides and nickelates, which exhibit superconductivity at high pressures. A major goal is to investigate spatial variations in critical temperature and correlate these with material composition and structure, using high-resolution mapping techniques. NV centres, which are atomic-scale defects in diamond sensitive to local magnetic fields, will be employed to probe superconducting properties at the microscopic level.
These sensors allow for optical readout and can be integrated into high-pressure experiments. The project will also utilize synchrotron x-ray diffraction, Raman scattering, and bulk transport measurements to provide complementary spatially-resolved data. Another focus is on measuring the lower critical field of clean superconducting samples, which provides insight into the mechanisms of superconductivity and quantum phase transitions.
The research is highly collaborative, involving Dr Sven Friedemann (expert in high-pressure measurements) and Dr Krishna Coimbatore Balram (expert in NV centre quantum sensors). Students will have opportunities to work at Bristol and participate in experiments at national and international synchrotron facilities. The School of Physics offers a vibrant graduate research community, comprehensive induction, targeted skills training, and strong support for diversity and career development.
Funding is available for home students (covering stipend, tuition, and training), with a limited number of fully-funded places for outstanding international candidates. Applicants should have a strong background in physics or a related field, and meet the University's English language requirements.
The application deadline is 19 January 2026. For more information, contact the Bristol Physics Graduate School at [email protected].

What's required
Applicants must have 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. International applicants should consult the University of Bristol's International Office for country-specific requirements. If English is not your first language, you must meet English Language Profile F as specified by the University of Bristol. No research proposal is required, but you must specify a research theme or academic supervisor. Applications are assessed on merit and shortlisted candidates will be interviewed.
