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 demonstrate the following results: (i) given a generic observable A, the infinite time average of the quantum expectation value is independent of all aspects of the initial state other than the total energy, and equal to an appropriate thermal average of A; (ii) the time variations of are too small to… 
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
Thermalization and its mechanism for generic isolated quantum systems
TLDR
It is demonstrated that a generic isolated quantum many-body system does relax to a state well described by the standard statistical-mechanical prescription, and it is shown that time evolution itself plays a merely auxiliary role in relaxation, and that thermalization instead happens at the level of individual eigenstates, as first proposed by Deutsch and Srednicki.
Time fluctuations in isolated quantum systems of interacting particles.
TLDR
It is shown that the coefficient of the exponential decay depends on the level of delocalization of the initial state with respect to the energy shell, and the results suggest that they decay exponentially with system size in both regimes, integrable and chaotic.
On the onset of thermalization in closed few particles systems: Classical and quantum results
A study of quantum-classical correspondence for the onset of thermalization in an isolated system of four interacting particles is presented. Provided that classical dynamics of the system is
New Equilibrium Ensembles for Isolated Quantum Systems
TLDR
A novel technique to generate progressively better approximations to ρDE is presented, which can be used to describe the equilibrium physics of small isolated quantum systems, going beyond the “thermal ansatz” of Gibbs ensembles.
Taking snapshots of a quantum thermalization process: Emergent classicality in quantum jump trajectories.
TLDR
The results show how to extend the framework of eigenstate thermalization to the prediction of properties of quantum measurements on an otherwise closed quantum system and show numerically the validity of the random matrix approach in quantum chain models.
Realistic Many-Body Quantum Systems vs. Full Random Matrices: Static and Dynamical Properties
TLDR
The von Neumann entanglement entropy with the Shannon information entropy is related and their relevance for the analysis of the degree of complexity of the eigenstates, the behavior of the system at different time scales and the conditions for thermalization is discussed.
Quantum coherence controls the nature of equilibration in coupled chaotic systems
A bipartite system whose subsystems are fully quantum chaotic and coupled by a perturbative interaction with a tunable strength is a paradigmatic model for investigating how isolated quantum systems
Relaxation and thermalization of isolated many-body quantum systems
We provide an overview of our numerical and analytical studies of isolated interacting quantum systems that are abruptly quenched out of equilibrium instantaneously. We describe the relaxation
Equilibration of isolated macroscopic quantum systems under experimentally realistic conditions
In how far does a non-equilibrium initial ensemble evolve towards a stationary long time behavior for an isolated macroscopic quantum system? We demonstrate that deviations from a steady state indeed

TLDR
A closed quantum-mechanical system with a large number of degrees of freedom does not necessarily give time averages in agreement with the microcanonical distribution, so by adding a finite but very small perturbation in the form of a random matrix, the results of quantum statistical mechanics are recovered.

TLDR
It is shown that a bounded, isolated quantum system of many particles in a specific initial state will approach thermal equilibrium if the energy eigenfunctions which are superposed to form that state obey Berry's conjecture, and argued that these results constitute a sound foundation for quantum statistical mechanics.

TLDR
It is found that within a semiclassical approximation the form factor for the fluctuations of quantum matrix elements around their classical average is proportional to the form factors for the density of states, with an amplitude determined by the squared average of the matrix elements.
