Scrambling, Locality, and Quantum Fluctuations

This talk will be about the physics of information scrambling in strongly interacting quantum many-body systems and gravity. I will present a new universality conjecture for the spread of information in quantum chaotic systems, and discuss evidence for it from new tensor network calculations and a new random circuit model that mimics AdS/CFT. I will also comment on applications to many-body localization and the relation to quantum chaos. Finally, I will briefly speculate about the manifestation of this universality conjecture in quantum gravity, where it seems related to unusually strong quantum effects.
