A random matrix formulation of fidelity decay
We propose to study echo dynamics in a random-matrix framework, where we assume that
the perturbation is time-independent, random and orthogonally invariant. This allows us to …

Universal spectral correlations in interacting chaotic few-body quantum systems
F Fritzsch, MFI Kieler - Physical Review E, 2024 - APS
The emergence of random matrix spectral correlations in interacting quantum systems is a
defining feature of quantum chaos. We study such correlations in terms of the spectral form …
