Description
Holographic investigations have revealed the importance of quantum chaos and random matrix theory in the unitary description of black holes. The spectral form factor associated with the $e^{S_{BH}}$ microstates that compose the black hole serve as a simple proxy for studying how perturbations to black holes thermalize. I will discuss how the details of the spectral statistics of the microstates manifest in the early and late time thermalization behaviour. Depending on the precise nature of the spectral statistics, it is possible for the spectral form factor to exhibit "regular oscillations."
In certain cases, such regular oscillations might be interpreted as being generated by Planck scale microstructure near the horizon which may be experimentally searched for in the aftermath of black hole merger events in the form of gravitational wave "echoes".
