PhD Position: Doping an Ideal Mott Insulator with Electrons
This PhD project at the University of Bristol explores the fascinating physics of Mott insulators, a class of materials whose electrons are localized due to strong Coulomb repulsion, despite having a half-filled electron band. By doping these insulators with electrons or holes, researchers can induce exotic metallic states and potentially high-temperature superconductivity. The project focuses on a family of recently-discovered compounds, Nb3X8 (where X = Cl, Br, or I), which are considered the best realization of an ideal single-band Mott insulator to date.
As a PhD student, you will collaborate with an international team, including theoreticians from Radboud University, to grow single crystals, dope them, and characterize their structural and electrical properties. The Quantum and Soft Matter Theme at Bristol provides access to dedicated materials synthesis and low temperature laboratories, as well as a vibrant community of staff and fellow PhD students for support and advice. The Bristol Doctoral College and the Physics Graduate School offer comprehensive induction, skills training, and career development resources.
The School of Physics at Bristol is renowned for its research excellence, ranked 5th in the UK (REF 2022), and the university itself is highly ranked globally. PhD scholarships are available, covering living expenses (UKRI rate), tuition fees, and training costs for home students. Outstanding international candidates may be eligible for a limited number of fully-funded places, and students with external funding are also welcome.
Applicants should have a first degree in physics or a related field, typically at least UK upper second-class honours, or a relevant master's qualification. International applicants must meet country-specific requirements, and all candidates whose first language is not English must satisfy English Language Profile F. The application process requires a CV, personal statement, and transcripts, submitted via the University of Bristol's online system. Early applications are encouraged, with a closing date of 19 January 2026.
This is an exceptional opportunity to join a world-class research environment, work on cutting-edge quantum materials, and develop advanced experimental and theoretical skills in condensed matter physics.
