The Memory Effect and Infrared Divergences - IPAM at UCLA

Explore a 45-minute lecture on "The Memory Effect and Infrared Divergences" presented by Robert Wald from the University of Chicago at IPAM's Workshop II: Mathematical and Numerical Aspects of Gravitation. Delve into the concept of the "memory effect" in gravitational radiation and its analogous phenomena in electromagnetism. Examine the challenges posed by infrared divergences in quantum field theory and the limitations of traditional Fock Hilbert space representations. Investigate the Kulish-Fadeev approach for massive quantum electrodynamics and its shortcomings in addressing null memory. Discover why scattering in quantum gravity may require a shift from Hilbert space formulations to algebraic incoming/outgoing states. Gain insights into collaborative research with Gautam Satishchandran and Kartik Prabhu, exploring the intricate connections between gravitational memory, gauge theories, and quantum scattering.
