Semiclassical foundation of universality in chaotic quantum circuits
Maximilian F. I. Kieler, Felix Fritzsch, Arnd Bäcker
The fundamental correspondence between quantum chaotic single-particle systems and random matrix theory is well-understood via periodic orbit theory. In contrast, we show that many…

Timescales for Deep and Full Thermalization
Tabea Herrmann, Felix Fritzsch, Arnd Bäcker
Isolated quantum systems typically approach thermal equilibrium as described by the Eigenstate Thermalization Hypothesis (ETH). Going beyond this involves either higher order corre…
