| Research Abstract |
The unique rheological properties of smectic phase can be understood through the unbinding transition of dislocation loops in connection with(i) the scaling behavior of the focal conic domain size,(ii) the temperature dependence of the yield stress,(iii) shear-induced smectic-nematic transition. In particular, by analyzing the shear rate and temperature dependence of the focal conic domain size, the physical origin of the elasticity of smectic phases.
