Abstract

We relate anharmonic equilibrium thermal fluctuations of smectics A to fluctuations of the Kardar-Parisi-Zhang (KPZ) dynamical model for a growing interface. The KPZ model in 1+1 dimensions is one to one related to a 2D smectic elastic model whose scaling behavior is then obtained exactly. The KPZ model in 2+1 dimensions maps into an elastic critical point of 3D smectics A with broken inversion symmetry (head-to-tail packing of layers). We discuss the elasticity and fluctuations of these novel smectic-A phases.
