A New Twist on the Electroclinic Critical Point: Type I and Type II Smectic Systems
Josh Ziegler, Sean Echols, Matthew J. Moelter +1
This analysis of the electroclinic effect in ferroelectric liquid crystals with a first order Smectic---Smectic- (Sm---Sm-) transition, shows they can be either…
Modeling the Field Control of the Surface Electroclinic Effect near Continuous and First Order Smectic-A*-Smectic-C* Transitions
Kara Zappitelli, Dana N. Hipolite, Karl Saunders
We present and analyze a model for the combination of bulk and surface electroclinic effects in the smectic-A* (Sm-A) phase near a Sm-A*--Sm-C* transition. As part of our analysis…
de Vries behavior of the electroclinic effect in the smectic-A* phase near a biaxiality-induced smectic-A* -- smectic-C* tricritical point
Karl Saunders
Using a generalized Landau theory involving orientational, layering, tilt, and biaxial order parameters we analyze the smectic-A* and smectic-C* (Sm-A* -- Sm-C*) transition, showin…
The Surface Electroclinic Effect near the First Order Smectic-A*--Smectic-C* transition
Karl Saunders, Per Rudquist
We analyze the surface electroclinic effect (SECE) in a material that exhibits a first order bulk smectic- (Sm-) -- smectic- (Sm-) transition. The effect of a c…
The Biaxial Smectic-A* Phase -- A New Phase, Already But Unknowingly Discovered?
Karl Saunders
The biaxial smectic-A* (Sm-A_B*) phase, appearing in the phase sequence Sm-A*--Sm-A*_B--Sm-C*, is analyzed using Landau theory. It is found to possess a helical superstructure with…
De Vries Behavior in Smectics near a Biaxiality Induced Smectic A - Smectic C Tricritical Point
Karl Saunders
We show that a generalized Landau theory for the smectic A and C phases exhibits a biaxiality induced AC tricritical point. Proximity to this tricritical point depends on the degre…
