Abstract
We present a phenomenological model for the phase transition between the monolayer () and the bilayer () phases of smectic liquid crystals. This model contains all relevant symmetries and Goldstone modes. We study the transition using the expansion and find it to be in the same universality class as the Ising model to first order in . In three dimensions, the physical correlation function, however, exhibits nonuniversal power-law behavior leading to a nonuniversal susceptibility exponent .
