Abstract

We formulate a simple Landau type model describing macroscopic behavior recently discovered in new smectic phases composed of achiral bent-shaped molecules. Films of such smectics exhibit three types of ordering related to dipole polarization, molecular tilt, and chirality. However, due to specific third-order coupling of the order parameters, these three symmetry-breaking types are not independent and this fact leads to specific domain structures that are observed in experiments.
