Explore quantum criticality phenomena in black hole scattering through this high energy physics seminar presented by Uri Kol from Harvard University. Discover how black hole perturbation theory captures crucial effects in binary merger dynamics, including tidal deformations, ringdown mode decay, and photon ring physics. Learn about a newly identified critical phenomenon in Kerr black hole perturbation theory that emerges at zero black hole temperature, creating a critical point that governs finite-temperature regimes dominated by critical perturbations. Examine how this quantum many-body system analogy leads to physics described exclusively by critical exponents, resulting in universal behavior that produces robust and distinctive predictions unique to Kerr geometry. Understand the theoretical framework's potential for generating qualitative results and reliable predictions, addressing long-standing challenges in extracting meaningful insights from black hole perturbation theory amid remarkable experimental advances in gravitational wave detection and black hole imaging.
