abstract
We propose a novel measure of chaotic scattering amplitudes. It takes the form of a log-normal distribution function for the ratios $r_n={\delta_n}/{\delta_{n+1}}$ of (consecutive) spacings $\delta_n$ between two (consecutive) peaks of the scattering amplitude. We show that the same measure applies to the quantum mechanical scattering on a leaky torus as well as to the decay of highly excited string states into two tachyons. Quite remarkably the $r_n$ obey the same distribution that governs the non-trivial zeros of Riemann zeta function.

Bootstrapping black holes at low impact parameter
After subtracting the eikonal carrier, the residual SDR spectrum in six dimensions organizes into a cap-saturated low-impact band, an empty gap, and Regge-like ridges whose weak-coupling edge is the G_N=0 baseline.

In holographic confining backgrounds, temporal peak statistics of boundary correlators after local quenches approach the Gaussian Symplectic Ensemble for heavy operators and, in capped BTZ, even for massless ones.

Spectral form factors for curved spacetimes with horizon
The spectral form factor of brick-wall normal modes shows a random-matrix-like dip-ramp-plateau for both BTZ and de Sitter horizons, while the generalized three-level form factor distinguishes these integrable systems...

Higher-dimensional chaotic features and random matrix signatures following a local quench
Extrema of local-quench two-point functions in free 1+1 and 2+1 scalar theory show soft-to-GOE nearest-neighbor repulsion and geometry-dominated all-pair form factors.
