Sound attenuation and dispersion near the nematic-smectic A phase transition of a liquid crystal

Year: 1979

Type: article

Abstract: The time dependent Ginzburg-Landau theory of the nematic-smectic A transition is generalized to include coupling of the order parameter to the density. This coupling gives rise to a divergence in the bulk viscosities near the transition, which causes an isotropic anomalous attenuation of sound. The coupling also gives a contribution to the speed of sound near the transition. These results are in agreement with recent experiments.
