Effective field theories from on-shell amplitudes (GA21-26574S)

We plan to focus on theoretical aspects of the low-energy effective field theories. In recent years our team and several other groups initiated a systematic study of the S-matrix in these theories, finding some remarkable structures and relations. We...

Adaptive control of nonlinear waves in circular resonators (GA202/98/P240)

Renewed interest in finite-amplitude acoustic waves in confined geometries has been stimulated by developments in acoustic compressors, thermoacoustic engines standing wave in a resonant cavity. When a standing wave is driven to hig...
