Signatures of chaos and thermalization in the dynamics of many-body quantum systems.
We extend the results of two of our papers [Phys. Rev. A 94, 041603R (2016) and Phys. Rev. B 97, 060303R (2018)] that touch upon the intimately connected topics of quantum chaos and thermalization. In the first, we argued ...
Thouless and Relaxation Time Scales in Many-Body Quantum Systems.
Studies of the dynamics of isolated interacting many-body quantum systems are at the forefront of experimental and theoretical physics. A major open question is the identification of the time scales involved in the ...
From few- to many-body quantum systems.
(IOP Publishing, 2018-09-03)
How many particles are necessary to make a quantum system many-body? To answer this question, we take as reference for the many-body limit a quantum system at half-filling and compare its properties with those of a system ...
Realistic Many-Body Quantum Systems vs. Full Random Matrices: Static and Dynamical Properties.
We study the static and dynamical properties of isolated many-body quantum systems and compare them with the results for full random matrices. In doing so, we link concepts from quantum information theory with those from ...
Self-averaging in many-body quantum systems out of equilibrium.
Despite its importance to experiments, numerical simulations, and the development of theoretical models, self-averaging in many-body quantum systems out of equilibrium remains underinvestigated. Usually, in the chaotic ...
Self-averaging behavior at the metal-insulator transition of many-body quantum systems out of equilibrium .
An observable of a disordered system is self-averaging when its properties do not depend on the specific realization considered. Lack of self-averaging, on the other hand, implies that sample to sample fluctuations persist ...
