20. It can be shown, by an elementary application of the Landauer-Büttiker formalism, that this relation remains valid in the presence of backscattering.

22. BT/e* the peak is effectively washed out in the measurements.
23. A closely related theoretical question is that the value of the ΧLL coupling constant g may differ from the "canonical" value g = ν, assumed here. See, for example, Sudanshu S. Mandal and J. Jain, Phys. Rev. Lett. 89, 096801 (2002); B. Rosenow and B. I. Halperin, ibid. 88, 096404 (2002).
