DESCRIPTION:Title: <a href="https://researchseminars.org/talk/EASW/7/">Cau
 sal symmetry breaking: late time physics of holographic quantum chaos</a>\
 nby Julian Sonner (U. Geneva) as part of East Asian String Webinars\n\n\nA
 bstract\nQuantum chaotic systems are often defined via the assertion that 
 their spectral statistics coincides with\, or is well approximated by\, ra
 ndom matrix theory. In this talk I will explain how the universal content 
 of random matrix theory emerges as the consequence of a simple symmetry-br
 eaking principle and its associated Goldstone modes. Within AdS/CFT this g
 ives a universal framework to express correlations between "different univ
 erses"\, even for individual theories rather than ensembles. I will illust
 rate 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 als
 o in higher dimensional field theories\, as applicable for example for hig
 her-dimensional AdS/CFT dual pairs.\n
