Soft elasticity in biaxial smectic and smectic-C elastomers.
Ideal (monodomain) smectic-A elastomers cross-linked in the smectic-A phase are simply uniaxial rubbers, provided deformations are small. From these materials smectic-C elastomers are produced by a cooling through the smectic-A to smectic-C phase transition. At least in principle, biaxial smectic elastomers could also be produced via cooling from the smectic-A to a biaxial smectic phase. These ...

We discuss the macroscopic properties of several classes of polar liquid crystalline phases. We focus on polar biaxial liquid crystalline phases made of achiral molecules with ̄uidity in two and three spatial dimensions. The classes we examine include polar biaxial nematic phases, orthogonal biaxial smectic phases with anisotropic in-plane ̄uidity and tilted polar biaxial smectic phases with in...
متن کاملTheory and simulation of biaxial nematic and orthogonal smectic phases formed by mixtures of board-like molecules
Variational cluster calculations and Monte Carlo simulations are applied to hard-body board-like models of biaxial molecules forming liquid crystalline phases. The molecular long axes are assumed for simplicity to be fully oriented. Depending on the extent of transverse anisometry in the molecular shape, these systems can exhibit biaxial nematic phases as well as uniaxial and biaxial orthogonal...
متن کاملBiaxial mesophase behavior of amphiphilic anisometric colloids: a simulation study.
The phase behavior of amphiphilic anisometric particles is explored using Monte Carlo simulations. The particles are composed of two incompatible laterally attached units: a spherocylinder and a spheroplatelet. A liquid crystalline phase polymorphism is obtained including biaxial nematic, (quasi long range biaxial) calamitic smectic-A, biaxial lamellar and columnar phases. The simulation result...
متن کاملBiaxial phases in mineral liquid crystals
A review is given of liquid crystals formed in colloidal dispersions, in particular those consisting of mineral particles. Starting with the historical development and early theory, the characteristic properties related to the colloidal nature of this type of liquid crystals are discussed. The possibility to find biaxial nematic and smectic phases is described for mixtures of rods and plates an...
