    • Including the full triplet degeneracy would decrease the calculated current along the blockaded triangle edges by roughly a factor of 2. While we cannot quantitatively fit to the model given the asymmetry between the electron and hole triangles, the current amplitude with no degeneracy does seem correct to better than a factor of 2. One possibility is that the singlet and ms=0 triplet may be mixed by nuclei (see Ref.) making the effective degeneracies of blockaded and unblockaded states equal.
