a Schematic illustration of ENAQT. At finite dephasing, \(L\left(\varGamma,\Delta \right)\) defines a larger step-size than a classical random walk, and weak dephasing can destroy the phase coherence responsible for Anderson localization and induce transport between coherent segments. b A maximum (purple filled circle) of long-time diffsuion Ds is predicted at a turnover temperature Tt when \(\varGamma \approx \Delta\), which is the essence of ENAQT, diffusivity is plotted as unitless \(D/J{a}^{2}\). c–e Experimentally measured Ds and \({D}_{\max }\) for DAB-1 (c), DAB-2 (d), and OA-1 (e). The error bars represent standard deviation calculated from multiple separate measurements.
