Causal symmetry breaking: late time physics of holographic quantum chaos, Julian Sonner, University of Geneva
Quantum chaotic systems are often defined via the assertion that their spectral statistics coincides with, or is well approximated by, random matrix theory. In this talk I will explain how the universal content of random matrix theory emerges as the consequence of a simple symmetry-breaking principle and its associated Goldstone modes. Within AdS/CFT this gives a universal
framework to express correlations between ``different universes’’, including for individual theories rather than ensembles. I will Illustrate the bulk picture of this EFT using the example minimal string theory. I will end by discussing the construction of the EFT of quantum chaos also in higher dimensional field theories, as applicable for example for higher-dimensional AdS/CFT dual pairs.
