... it will necessarily reflect. When we go to quantum mechanics, deep wells will clearly localize the electronic states. More surprisingly, it can be shown that all the states in 1D get localized even for weak disorder. So even for E > Emax repeated scatterings on the potential can lead to localization ...

But before writing down the Feynman rules, I need to make another simplification: I’ll neglect the fact that both electrons and photons carry spin angular momentum, which can point in various directions. Pretending that all particles have spin zero will simplify the Feynman rules considerably, allowi ...
