    • Here we notice that Hiv has a contribution Viv that breaks U(1) symmetry, as well as a contribution that preserves the number of electrons within each valley; the former is exponentially small in a/ B while the latter, although only algebraically small, has negligible value (Ref.).

    • Here we should note that in the limit of very large mass anisotropy, the sigma-model description is no longer applicable and the system can be thought of an Ising model with coupling J∼ Δ0 D2, with ordering temperature Tc ∼J. For AlAs parameter values, this estimate gives ordering temperature similar to the one obtained from the sigma-model description.
