    • Neglecting Hbs is not always justified despite g1 being much smaller than g2,4. First, in the presence of spin, g1 processes "added" to the clean LL model are a "marginally relevant" or "marginally irrelevant" perturbation in the renormalization-group sense, depending on the sign of the bare g1 (see, e.g., Refs.). For repulsive Coulomb interaction (g1 >0), weak backward e-e scattering is marginally irrelevant, i.e., only leads to a small renormalization of the effective couplings of the LL theory on (exponentially) large spatial scales. We neglect the weak renormalization due to g1 processes altogether. Second, there exist phenomena which are entirely due to g1 processes. One of these is the spin-related magnetoresistance of a single-channel quantum wire (Refs.), which we will consider elsewhere (Ref.). However, for the effects studied in the present paper, it suffices to deal with forward e-e scattering only.

    • Under conditions 5.1 5.2, interaction drops out of the problem only within approximation 4.5, corresponding to g2 =0. The omitted factors with the exponent αr in Q make Q (0,τ) time dependent, which results in the renormalization of impurities-already taken into account in Eq. 4.2.

    • This should be contrasted with the regular configurations, where adding two lines (only diagrams with an odd number of impurity backscattering lines contribute to the Cooperon) multiplies the result for the conductivity by a small parameter (lee /l) 2, in view of dephasing.
