Light scattering from the free surface near a second order nematic to smectic a phase transition
2014 We have studied the spectrum of light scattered by surfaces waves thermally excited on the free surface of a nematic liquid crystal in a magnetic field near a second order nematic to smectic A phase transition. We have measured the surface tension and three viscosity coefficients. One of the viscosities diverges and its critical behaviour has been followed to within 3 mK of the transition....
متن کاملElastic constants and orientational viscosities of a bent-core nematic liquid crystal.
Using a combination of dynamic light scattering and Freedericksz transitions induced in applied magnetic and electric fields, we have determined the absolute magnitudes of the Frank elastic constants and effective orientational viscosities of the bent-core nematic liquid crystal, 4-chloro-1,3-phenylene bis 4-[4'-(9-decenyloxy)benzoyloxy] benzoate. At a fixed temperature 2 °C below the isotropic...
متن کاملCritical behaviour of a lattice model of the nematic to smectic-A transition
2014 The critical behaviour of a lattice version of the de Gennes model of the nematic to smectic-A transition is studied by Monte Carlo simulations. Several features observed in experiments are qualitatively reproduced in the simulations. The model exhibits a continuous phase transition with the specific heat exponent 03B1 close to zero. The order-parameter correlation functions show anisotrop...
متن کاملDefect model of the smectic A-nematic phase transition
2014 It is shown that phase transitions in three dimensions breaking up an ordered state by polar defect lines can be modelled on the xy model, at least if the interaction of the lines is only steric. The analogy is established for a lattice model by means of a xy high-temperature expansion for spin 1/2. The defect model is applied to the smectic A-nematic transition which is interpreted as a b...
متن کاملViscoelasticity of ambient-temperature nematic binary mixtures of bent-core and rodlike molecules.
We report measurements of the temperature variations of physical parameters in ambient-temperature nematic liquid crystal mixtures of bent-core (BC) and rodlike molecules (5CB): birefringence Δn; static dielectric constants ε(||) and ε(⊥); splay K(11) and bend K(33) elastic constants; rotational viscosity γ(1); and diffusion coefficients D(||) and D(⊥) of a microsphere. Both Δn and ε(||) decrea...
