Explore a high energy physics seminar where Caltech's Kathryn Zurek delves into the relationship between shockwave geometries and flat space holography. Learn how 't Hooft and Dray's shockwave operators' commutation relations connect to soft and Goldstone modes in celestial holography through a detailed examination of the diffeomorphism between shockwave and memory metrics. Discover the equivalence between shockwave effective action and modular Hamiltonian, understand the area law governing modular Hamiltonian fluctuations derived from 't Hooft commutation relations, and examine metric fluctuations resulting from vacuum energy fluctuations in shockwave production.
