20. Typically, Γ 1 as for graphene rings with irregular edges there are only evenascent modes present in each of the ring arms at zero and weak dopings, see Refs [7,8].
21. More generally, for centrosymmetric field B = B(r)̂ez, the parameter φ = φ12/φ0 in Eq. (7) is replaced by [10]: φ' = φ1/ φAB + 4π /φ0 ∫ r2 r1 dr/r ∫ r r1 dr'r'B(r), where φ1 is flux through the inner ring (r < r1). In particular, if B(r) = 0 for r > r1, the Aharonov- Bohm-like oscillations occur when varying φ1.
