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…
Symmetries and alignment of biaxial nematic liquid crystals
Panagiota K. Karahaliou, Alexandros G. Vanakaras, Demetri J. Photinos
The possible symmetries of the biaxial nematic phase are examined against the implications of the presently available experimental results. Contrary to the widespread notion that 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…
Tilt order parameters, polarity and inversion phenomena in smectic liquid crystals
P. K. Karahaliou, A. G. Vanakaras, D. J. Photinos
The order parameters for the phenomenological description of the smectic-{\it A} to smectic-{\it C} phase transition are formulated on the basis of molecular symmetry and structure…
