Explore the emerging field of Carrollian physics through this comprehensive workshop series that examines the mathematical curiosity of taking the speed of light to zero, creating spacetimes where lightcones collapse and causality breaks down. Discover how this seemingly abstract concept has found surprising relevance in modern theoretical physics, particularly in the geometry of null surfaces, Bondi-Metzner-Sachs symmetries, black hole horizons, inflationary cosmology, and holographic correspondences. Learn from leading experts as they present cutting-edge research on Carrollian holography, asymptotic symmetries of gravity, flat space holography, and the connections between Carroll symmetries and gravitational wave memory effects. Delve into advanced topics including BV-AKSZ approaches to asymptotic symmetries, twistor theory applications, soft graviton theorems, relativistic to Carroll hydrodynamics transitions, and fracton physics within Maxwell theory frameworks. Examine the mathematical foundations through discussions of BMS-like algebras, conformal field theory explorations, and the canonical structure of null Raychauduri equations. Investigate practical applications in celestial amplitudes, Carrollian conformal scalars, higher-spin gravity theories, and quantum field theory on asymptotically flat spacetimes. Gain insights into the latest developments in asymptotic structure analysis, superrotation Ward identities, hyperbolic mass concepts in lower dimensions, and the persistence of polyhomogeneity at null infinity. Understand how Carrollian physics bridges diverse areas of theoretical physics from fluid dynamics and holography to quantum geometry and gravitational wave theory.
