The approach to thermal equilibrium in quantized chaotic systems
We consider many-body quantum systems that exhibit quantum chaos, in the sense that the observables of interest act on energy eigenstates like banded random matrices. We study the time-dependent
Review of Particle Physics: Particle data group
This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2658 new measurements from 644 papers, we list, evaluate, and average measured properties of gauge
Thermal fluctuations in quantized chaotic systems
We consider a quantum system with N degrees of freedom which is classically chaotic. When N is large, and both and the quantum energy uncertainty are small, quantum chaos theory can be used to
Alternatives to eigenstate thermalization.
TLDR
It is shown that von Neumann's quantum ergodic theorem relies on an assumption that is essentially equivalent to ETH, and whether, following a sudden quench, special classes of pure states can lead to thermal behavior in systems that do not obey ETH, namely, integrable systems.
