... most convenient to work with the oracle which behaves as follows: Of (|xi|bi) = |xi|b ⊕ f (x)i, where b is an m-qubit string. We have the promise that f is periodic; namely for some s ∈ ZN \ {0}, f (x) = f (x + s) for all x ∈ ZN . Otherwise, all of f ’s values are assumed to be distinct: that is, we ...

In the graphene case, B = 400T corresponds to φ ≈ 0.005φ0 When ta = tb = 1 and tc = 2, two zero modes in the Brillouin zone merge into a confluent mode at H = 0[18].
