a–c, Time evolution of several heliknoton lattices perturbed from equilibrium by increasing the applied voltage. Black double arrows indicate crossed polarizer orientations. In (b), sample thickness d = 17.5 μm, pitch p = 5.4 μm, and applied voltage U = 1.8 V in the first frame and 2.3 V in subsequent frames. In (a) and (c), d = 16 μm, p = 6.9 μm, and U = 1.7 V in the first frame and 2.1 V in subsequent frames. The real-time dynamics of transformations corresponding to a and c is shown in SI Video 8.
