a The lattice geometry of the 1D SL. b Chiral edge currents with phases θ = π∕4 (red) and 3π∕4 (blue). Coupling strengths κ = 0.15 (dotted) and 1 (solid). The currents with phases θ = 0, π∕2 are zero (not shown). c Energy bands of SLs with different phases θ = 0, π∕4, π∕2. Coupling strengths κ = 0.5. In all plots, Ωr = 1 and Δc = 2κ.
