Abstract

The first observation is reported of an anomalous attenuation and velocity dispersion near a smectic-A-smectic-C phase transition in a liquid crystal. The anomaly is found to be strongly anisotropic and dominated by the Landau-Khalatnikov relaxation of the order parameter in contrast with other liquid-crystalline phase transitions.
