Metrological quantum-to-classical crossover in the volume of a noisy quasiperiodic lattice

Localization-delocalization transitions have recently been proposed for building a class of efficient quantum many-body critical sensors. This work scrutinizes metrological performances of such devices by focusing on the Aubry-Andr\'e-Harper model that supports a localization-delocalization transition at finite strengt...
