ISSP-IIS Joint Symposium on
Physics of Open Systems: Resonance, Symmetry and Topology

The Institute for Solid State Physics (ISSP) and the Institute of Industrial Science (IIS), both located on the Kashiwa Campus of the University of Tokyo, are co-organizing the international workshop titled “Physics of Open Systems: Resonance, Symmetry, and Topology.”

This workshop explores the physics of open systems in the broadest sense. We aim to bring together researchers working across a wide range of disciplines―from classical to quantum regimes―to stimulate cross-disciplinary discussions and foster the emergence of a new paradigm in the study of open systems.


Date and Place

  • Date: Monday, August 4 - Friday, August 8, 2025
  • Venue: Media Hall, 1st Floor, Kashiwa Library
  • Campus: Kashiwa Campus, The University of Tokyo (Chiba, Japan)

Focused topics (but not limited)

  • Open systems (quantum, photonic, cold atoms, mechanical systems, etc.)
  • Resonance dynamics
  • Non-Hermitian physics
  • Topological aspects of non-Hermitian systems
  • Floquet topological systems
  • Non-equilibrium phenomena
  • Measurement-induced phenomena
  • Metastable and long-lived states
  • Classical and quantum relaxation dynamics
  • Active matter and biological systems
