Doctoral Student in Theoretical Condensed Matter Physics
The Department of Physics at KTH Royal Institute of Technology in Stockholm, Sweden, invites applications for a doctoral student position in Theoretical Condensed Matter Physics, supervised by Professor Egor Babaev. The research group is renowned for its broad spectrum of theoretical investigations, employing both analytical and numerical methods to address fundamental questions in condensed matter physics. Areas of focus include effective field theory, topological solitons, statistical mechanics of phase transitions, topological systems, and advanced quantum many-body techniques.
One of the group’s cutting-edge research topics is the study of composite order, highlighted by recent experimental discoveries such as the electron quadrupling condensate and topological defects carrying arbitrary fractions of magnetic flux quantum. These findings have challenged long-standing paradigms and opened new avenues for exploring the nature and applications of novel quantum states of matter. Additional research themes include quantum symmetry-breaking, topologically ordered states, unconventional phase transitions, and the use of innovative computational methods like Diagrammatic Monte-Carlo to tackle persistent problems in the field.
The successful candidate will have opportunities to collaborate with both local and international theoretical and experimental groups, fostering a dynamic and interdisciplinary research environment. The position is full-time, with employment for up to four years, and includes a monthly salary in accordance with KTH’s doctoral student salary agreement, as well as access to a range of employee benefits.
Eligibility requirements include a completed second cycle degree (such as a master’s) or at least 240 higher education credits, with a minimum of 60 credits at the second-cycle level, or equivalent knowledge. Proficiency in English equivalent to English B/6 is mandatory. Selection criteria emphasize the ability to work independently and collaboratively, a professional approach, and strong analytical skills. Personal attributes are highly valued in the selection process. Security clearance may be required for certain positions.
To apply, candidates must submit a complete application via KTH’s recruitment system, including a CV, application letter (maximum two pages), certified copies of diplomas and grades, proof of language proficiency, and representative publications or technical reports. All documents must be submitted by the deadline of January 7, 2026.
KTH Royal Institute of Technology is a leading international technical university committed to advancing education, research, and innovation for a sustainable future. The university offers a creative and dynamic environment, excellent working conditions, and a strong commitment to equality, diversity, and equal opportunities.
