Abstract
In this Rapid Communication we derive a simple dynamical model for the unwinding transition of a cholesteric liquid crystal. Our model descr ibes not only the equilibrium but also the nonequilibrium features of the transition. In particular, our model is in qualitative agreement w ith the experimental observations of systems containing rotating spira l waves, all of the same handedness.
