Fréedericksz transition in antiferroelectric liquid crystals and cooperative motion of smectic layers

A.M. Rudin and P. L. Taylor

September 4, 1998

Abstract:

We study the theory of the Fréederiksz transition in antiferroelectric liquid crystals and find the conditions under which an applied electric field can cause a homogeneously nucleated transition of the system from antiferroelectric to ferroelectric alignment. We demonstrate that taking into account the cooperative motion of smectic layers results in a significant reduction of the predicted critical electric field at which this transition occurs.
