PhD Position in Theoretical Condensed Matter Physics KTH Royal Institute of Technology in Sweden

KTH Royal Institute of Technology is advertising a doctoral position in theoretical condensed matter physics within the group of Professor Egor Babaev at the Department of Physics in Stockholm, Sweden.

The project focuses on a broad range of modern topics in condensed matter theory, combining analytical and numerical approaches. Research directions mentioned in the advertisement include effective field theory, topological systems, topological solitons, statistical mechanical descriptions of phase transitions, and modern microscopic quantum many-body techniques. The group also works on emerging forms of order such as electron quartet condensates and topological defects carrying arbitrary fractions of the magnetic flux quantum, as well as new symmetry-breaking quantum states, topologically ordered states, unconventional phase transitions, and computational approaches such as diagrammatic Monte Carlo.

The position is part of KTH’s PhD education in physics. The advertisement emphasizes collaboration with international theoretical and experimental research groups involved in the project, making it attractive for candidates interested in a highly active and internationally connected research environment.

Eligibility highlights: applicants must meet the general admission requirements for doctoral studies, meaning a second-cycle degree or equivalent preparation equivalent to at least 240 higher education credits including 60 advanced-level credits. An English qualification equivalent to English B/6 is required. Selection is based on the candidate’s ability to work independently, collaborate, take a professional approach, and handle complex problems; personal suitability is given significant weight.

Funding and employment: the successful applicant will be employed as a doctoral student at KTH, with a monthly salary according to KTH’s doctoral salary agreement. The employment is time-limited and may last up to four years full-time, in line with doctoral study duration.

How to apply: applications must be submitted via KTH’s recruitment system. The application should include copies of degree certificates and transcripts, proof of language eligibility, a CV, a motivation letter describing research interests and future goals, and representative publications or technical reports. If documents are not in English or Swedish, translations are required. The deadline is 2026-10-07.

This is a strong fit for candidates interested in theoretical condensed matter physics, quantum many-body theory, topological phases, phase transitions, and advanced computational physics methods.
