A rigorous hydrodynamic theory of the A-B transition is presented. All dissi-pative processes are considered. At low interface velocities, those occurring on hy-drodynamic length scales, not considered hitherto, are most probably the dominant ones.

We consider the effect of weak nonmagnetic disorder on two chains of interacting fermions (with and without spins) coupled by interchain hopping. For the spinless case, interchain hopping increases localization for repulsive interactions but stabilizes the s-wave superconducting phase for attractive interactions. For the case with spin, the d-wave phase arising from purely repulsive interaction...
