About this position
RIKEN’s Center for Interdisciplinary Theoretical and Mathematical Sciences (iTHEMS) is offering a number of postdoctoral researcher positions in the Category Theoretical Physics RIKEN ECL Research Unit, led by Kantaro Ohmori. The unit sits within an interdisciplinary research hub that connects mathematics and theoretical science across areas such as nature, life, society, and information.
The project is part of the JST PRESTO research area “Uncharted Quantum” and focuses on building a framework for systematically constructing lattice models that realize quantum phases from categorical and algebraic descriptions of quantum field theory. The research direction combines generalized and non-invertible symmetries, higher algebra, and related structures with tools such as tensor networks and lattice models.
Successful researchers will work on one or more topics closely tied to the unit’s programme, including:
- categorical and algebraic structures in quantum field theory
- conformal field theory and topological field theory
- quantum many-body systems and their constructive descriptions
- mathematical structures relevant to quantum field theory
The role is embedded in an interdisciplinary environment, with an expectation of active exchange with researchers from other fields at iTHEMS. Applicants may also propose independent research themes, provided they contribute to the goals of the Unit.
The position is based at RIKEN Wako Campus in Wako, Saitama, Japan.
Funding details
One-year fixed-term postdoctoral employment, renewable based on evaluation up to March 31, 2030. Salary at hiring is 480,000 JPY or more per month including discretionary work allowance, with commuting and housing allowances and social insurance.
What's required
The candidate should possess a doctoral degree or be expected to obtain a doctoral degree by the starting date. Applicants should have research interests aligned with categorical and algebraic structures in quantum field theory, generalized and non-invertible symmetries, conformal field theory, topological field theory, quantum many-body systems, tensor networks, category theory, higher algebra, or algebraic topology. The post also welcomes proposals for the applicant's own research themes that contribute to the Unit and an active interest in interdisciplinary exchange. Two letters of recommendation are required, along with a cover letter, CV, publication list, research statement, research plan, interdisciplinary statement, and personal information consent form.
How to apply
Upload all required application documents through the provided application page. Include the job position number 26-1454 in the notes section of your CV. Submit the required recommendation letters and consent form with the rest of the materials.
