12. It is always true that (Formula presented) However, the concept of dephasing implies that (Formula presented) for long trajectories. The assumption of having short (Formula presented) is important here. If we take (Formula presented), then some important interference contribution will not be suppressed in the (Formula presented) limit. See Ref. 8 for details. This observation is essential in order to understand, within the path-integral approach, why static disorder leads to either weak or strong localization effect.
13. Obviously, these three effects come out naturally from the solution of the DLD model. Note, however, that localization effect is out of the scope of the preset application.
