Description
In this talk (based on arXiv 2507.18746 and 2507.22999) I will show that in a massive scalar theory on a finite cylinder, operator local perturbations(quenches) drive dynamics whose time-resolved two-point functions exhibit spacing-ratio statistics along with other measures showing clear random-matrix behaviour. Extending to holography, I construct confining deformations by capping off AdS (and BTZ) with a hard wall and derive exact Green’s functions for post-quench evolution. In these confining backgrounds, fluctuations of boundary observables approach Wigner–Dyson behavior, with chaotic signatures amplified for heavier operators and for walls placed closer to the boundary.
