Abstract:

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’’, even 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.
