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 ...
Positive quantum Lyapunov exponents in classically regular systems.
Quantum chaos refers to signatures of classical chaos found in the quantum domain. Recently, it has become common to equate the exponential behavior of the quantum evolution of out-of-time order correlators (OTOCs) with ...
Level Repulsion and Dynamics in the Finite One-Dimensional Anderson Model.
(Philip Allan Publishers Limited, 2019-09-12)
This work shows that dynamical features typical of full random matrices can be observed also in the simple finite one-dimensional (1D) noninteracting Anderson model with nearest neighbor couplings. In the thermodynamic ...
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 ...
