21. We assume that the leads and channel are biased in such a way as to approximately align the lowest subbands in these different regions
22. Valley-independent energy correction is ignored here because it does not contribute to the wave vector difference [shown in Eq.] and hence has no effects on the valley precession.
23. 0 and D considered here.
