5. See, e.g., P. E. Cladis (unpublished, 1987), where a flexoelectric effect is used to locally unwind a helical structure without introducing defects; A. Saupe (unpublished, 1977), who shows that by escaping into the third dimension, a cholesteric helix may be completely unwound without introducing defects; P. E. Cladis, A. E. White, and W. F. Brinkman, [J. Phys. (Paris) 40, 325 (1979)] who show that, to minimize its elastic energy, an S = 2 defect with a core region that has escaped into the third dimension rotates with the opposite handedness to that given by the microscopic chirality
