Seeking a Team Director (Principal Investigator, Indefinite-term) (25-3616) Full-time

Team Director (Principal Investigator, Indefinite-term)

Quantum Mathematics Research Team (tentative name) Fundamental Quantum Science Program, TRIP Headquarters

RIKEN's research is based on comprehensiveness and interdisciplinarity, and with free thinking as its basic philosophy, RIKEN promotes research that goes beyond the boundaries of conventional research fields, while at the same time responding to the needs of society from a strategic perspective.

Fundamental Quantum Science Program focuses on four key areas — basic physics and chemistry, mathematics, quantum information, and nonequilibrium science — returning to the foundations of quantum science and advancing research from a mid- to long-term perspective.

Mathematics provides the foundation for quantum theory, while the development of quantum physics often stimulates new advances in mathematics. Consequently, mathematics related to quantum theory is expected to have significant synergy effects and maintain close connections with other three fields studied by this program: fundamental physics and chemistry, nonequilibrium science, and quantum information.

This call seeks a team director (principal investigator) to lead the fundamental quantum mathematics research, e.g., in the following fields: (a) quantum geometry and noncommutative geometry, (b) K-theory and topological quantum states, (c) mathematical physics of quantum many-body systems, and (d) topological quantum phases and quantum information.
