Question:
Recall that in lecture 4, parts II and III, we considered the effects of localization in weakly disordered systems. In this class of systems, why are closed loops the dominant contribution to localization?
Solution:
This question is trivial after watching the video. The reason why closed loop contributes to localization is because a closed loop can be traversed in two ways so that they don't cancel each other.
