38. r(η) as a direct product which is not correct in general.
39. One must also be careful when interpreting the extrema of the interference term of Eq. (B3) (as a function of magnetic field in the Ahronov-Bohm experiment, for example) as a measure of the coherence. The difference of the maximum and minimum of the interference term must be normalized by the direct terms to divide out Debye-Waller factors which reduce both the direct terms above and the interference cross terms [42]. In general one must normalize the interference term by a flux dependent term to prevent "flux blocking" effects from being interpreted as decoherence.
40. As SAI point out, what matters is the relative phase of the two arms of the Aharonov-Bohm ring. We are taking V(x(t)) = 0 in the left arm.
