Hierarchical analytical approach to universal spectral correlations in Brownian Quantum Chaos
Tara Kalsi, Alessandro Romito, Henning Schomerus
We develop an analytical approach to the spectral form factor and out-of-time ordered correlators in zero-dimensional Brownian models of quantum chaos. The approach expresses these…

Spectral chaos bounds from scaling theory of maximally efficient quantum-dynamical scrambling
Tara Kalsi, Alessandro Romito, Henning Schomerus
A key conjecture about the evolution of complex quantum systems towards an ergodic steady state, known as scrambling, is that this process acquires universal features when it is mo…
