Localisation and Transport in Driven Quantum SysteMS

Abstract

Noise is often seen as a source of unwanted decoherence in quantum systems, but this need always not be the case. In this thesis, numerical investigations of the dynamics of a quantum model that shows a localisation transition are carried out, and the effects of noise on the transport and localisation are studied. Sharp dynamical transitions as well as robustness to decoherence are found, along with a tunability of dynamics solely by noise, even when a translationally invariant model is considered, offering novel opportunities for Floquet engineering. Numerical estimates and hypotheses are made for the conditions that enable the observed phenomena.
