Light scattering study of the "pseudo-layer" compression elastic constant in a twist-bend nematic liquid crystal
Z. Parsouzi, Shokir A. Pardaev, C. Welch +9
The nematic twist-bend (TB) phase, exhibited by certain achiral thermotropic liquid crystalline (LC) dimers, features a nanometer-scale, heliconical rotation of the average molecul…
Second harmonic light scattering induced by defects in the twist-bend nematic phase of liquid crystal dimers
Shokir A. Pardaev, S. M. Shamid, M. G. Tamba +8
The nematic twist-bend () phase, exhibited by certain thermotropic liquid crystalline (LC) dimers, represents a new orientationally ordered mesophase -- the first…
Theory of Polar Blue Phases
Shaikh M. Shamid, David W. Allender, Jonathan V. Selinger
In liquid crystals, if flexoelectric couplings between polar order and director gradients are strong enough, the uniform nematic phase can become unstable to formation of a modulat…
Landau theory-based estimates for viscosity coefficients of uniaxial and biaxial nematic liquid crystals
Shaikh M. Shamid, David W. Allender
Using Landau theory, it is shown that eight phenomenological parameters are needed to describe and distinguish the twelve viscosity coefficients of a biaxial nematic phase, or the…
Landau-deGennes Theory of Biaxial Nematics Re-examined
David Allender, Lech Longa
Recent experiments report that the long looked for thermotropic biaxial nematic phase has been finally detected in some thermotropic liquid crystalline systems. Inspired by these e…
