Abstract

Heat-capacity and optical measurements in free-standing films of a chiral smectic liqui-crystal material which exhibits novel fluctuation effects, as well as a remarkable set of N-dependent transitions among different states of tilt organization were carried out. It was found that the profiles of the associated heat-capacity anomalies are strongly thickness dependent and exhibit a novel crossover behavior in reduced dimensions. Further, the anticlinic coupling between tilted surface layers in the smectic-A phase was characterized.
