Mini-Workshop on Cavities for Fundamental Physics

28 Apr 2026, 09:00 → 30 Apr 2026, 19:00 Asia/Shanghai

Tsung-Dao Lee Institute/N4F-N400 - meeting room (Tsung-Dao Lee Institute)

Resonant cavities have become powerful tools for probing ultralight bosonic dark matter and high-frequency gravitational waves. Recent experimental and theoretical advances are rapidly expanding their capabilities, enabling searches over broader parameter ranges and for a wider variety of target signals. This mini-workshop aims to bring together researchers working on cavities and related techniques to discuss recent progress and explore new possibilities for probing fundamental physics, particularly beyond their traditional applications.
