Fig. 5

The Bessel function difference for (a) ∣J1(f1)∣ − ∣J1(f2)∣ with f2 = 1.3 and (d) ∣J2(f1)∣ − ∣J2(f2)∣ with f2 = 2.1. The transmission difference for (b) ΔT(Δ = Ï‰) with f2 = 1.3 and (e) ΔT(Δ = 2ω) with f2 = 2.1 as a function of f1. The black dashed lines indicate the phase transition lines. Insets: schematics of the topological phases of the associated 1D lattice H(n) along \({\hat{m}}_{1}+n{\hat{m}}_{2}\) for (b) n = 1 and (e) n = 2. The (c, f) present the Zak phase prediction and transmission measurement, respectively. Here the parameters are t1 = t2 = 25 MHz. The error bars represent standard deviation calculated from five independent data points.
