The Effect of Solutes on the Temperature of Miscibility Transitions in Multi-component Membranes
D. W. Allender, M. Schick
We address questions posed by experiments which show that most small-chain alcohols reduce the miscibility transition temperature when added to giant plasma membrane vesicles, but…
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…
Surface states in nearly modulated systems
A. E. Jacobs, D. Mukamel, D. W. Allender
A Landau model is used to study the phase behavior of the surface layer for magnetic and cholesteric liquid crystal systems that are at or near a Lifshitz point marking the boundar…
