Splay Stiffening and Twist Softening in a Ferroelectric Nematic Liquid Crystal
Evangelia E. Zavvou, Alexander Jarosik, Hajnalka Nádasi +5
The recent discovery of ferroelectric nematics-genuine 3D ferroelectric fluids-has underscored the importance of electrostatic interactions in shaping the physical behaviour of sof…

Dipole-dipole correlations in the nematic phases of symmetric cyanobiphenyl dimers and their binary mixtures with 5CB
Evangelia E. Zavvou, Efthymia Ramou, Ziauddin Ahmed +4
We report on the temperature dependence of birefringence and of the static dielectric permittivity tensor in a series of binary mixtures between the symmetric, bent-shaped, 1",9"-b…

On the molecular theory of dimer liquid crystals
P. K. Karahaliou, A. G. Vanakaras, D. J. Photinos
We present a statistical mechanics approximation scheme for the explicit treatment of spacer-mediated configurational correlations among the mesogenic units that form a dimer molec…
