Noise-induced transport in the Aubry-André-Harper model
Noise-induced transport in the Aubry-André-Harper model
We study quantum transport in a quasiperiodic Aubry-André-Harper (AAH) model induced by the coupling of the system to a Markovian heat bath. We find that coupling the heat bath locally does not affect transport in the delocalized and critical phases, while it induces logarithmic transport in the localized phase. Increasing …
