Crumpling and second sound in lyotropic lamellar phases

T.C. Lubensky , Jacques Prost , S. Ramaswamy

We study relative concentration fluctuations in two component lamellar smectic liquid crystals consisting of surfactant layers of width w separated by a background fluid and show that these fluctuations are dominated by crumpling fluctuations of the surfactant layers when (w/l)2 <
