Step unwinding of a spiral in a cholesteric liquid crystal
Belyaev S.V. , Blinov L.M.
A nonmonotonic (step) dependence of the pitch of the cholesteric spiral on the magnitude of the field in a CLC layer, to the surfaces of which the director is attached, has been observed experimentally. Under these conditions for an abrupt turn-off of the relaxation of the unwound spiral is accompanied by the appearance of spatially modulated structures.
