We construct a two-channel scattering model for the triangular network ofvalley Hall states in interlayer-biased minimally twisted bilayer graphene fromsymmetry arguments and investigate electronic transport in a four-terminalsetup. In the absence of forward scattering, a single phenomenologicalparameter tunes the network between a triplet of chiral zigzag modes andpseudo-Landau levels. Moreover, the chiral zigzag modes give rise to robustAharonov-Bohm resonances in the longitudinal conductance in the presence of aperpendicular magnetic field or an in-plane electric field. Interestingly, wefind that when both a magnetic field and an in-plane electric field areapplied, the resonances of different zigzag branches split depending on theirpropagation direction relative to the in-plane electric field. We furtherdemonstrate that while the Hall response vanishes in the chiral zigzag regime,a finite Hall response is obtained without destroying the Aharonov-Bohmresonances in the longitudinal response, by weakly coupling different zigzagbranches, which also gives rise to Hofstadter physics at accessible magneticfields.
