Fig. 4

Evolution of Berry phase for a right-chiral, b left-chiral, and c achiral domain walls under the corresponding cyclic adiabatic processes. These processes are generated as the corresponding chiral domain walls move from right to left along the one-dimensional chain. Black (green) color denotes the total Berry phase up to the third (second) bands from the lowest band. Here, (α/t, δ/t) = (0.7, 0.7).
