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 ...
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 ...
