Description

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.
