Abstract

The dynamics and stochastic aspect of the vortices that occur in a smectic-A liquid crystal close to its nematic-smectic A transition point is investigated. Using the analogy between our target system and the superfluid system, we discuss following two topics: The first topic is the formulation of the equation of motion of the vortex center, and the other one is the analysis of the random behavior of the vortices.
