26. Note that this definition is different from the Δ used in Ref. 16. The Δ defined in Ref. 16 is appropiate only for homogenous systems.
27. Strong scattering (diffusive) effects are negligible at B = 0, see, e. g., L. Zheng and A.H. MacDonald, Phys. Rev. B 48, 8203 (1993).
28. Importantly, significant progress towards fabricating modulated one-dimensional nanowires has recently been achieved by M.S. Gudiksen, L.J. Lauhon, J. Wang, D.C. Smith, and C.M. Lieber, Nature (London) 415, 617 (2002).
29. This energy spectrum underlies the magnetoresistance oscillations discovered by D. Weiss, K. von Klitzing, K. Ploog, and G. Weimann, Europhys. Lett. 8, 179 (1989).
30. TF.i are the Thomas-Fermi screening wave numbers for the two layers. For the modulated layer the screening wave number has a slight temperature and density dependence, which, however, has a rather small effect for the calculated drag.
31. i vanishes when integrated over the Fermi surface. The sign-change is thus not a special property of the cosine-band.
