Switching mechanism in polar columnar mesophases made of bent-core molecules
Ewa Gorecka, Natasa Vaupotic, Damian Pociecha +2
The behavior of polar columnar phases made of bent shaped molecules (B_1Rev and B_1RevTilted) was studied under applied electric field. There are two competing mechanisms of switch…

General phase diagram for antiferroelectric liquid crystals in dependence on enantiomeric excess
E. Gorecka, D. Pociecha, M. Cepic +2
The phase diagram of the prototype antiferroelectric liquid crystal MHPOBC in dependence of enantiomeric excess was measured. It was shown that the SmCbeta phase in very pure sampl…

Short pitch structures in smectics with interactions over more than two layers
Mojca Cepic, Barbara Rovsek, Bostjan Zeks
Phenomenological model of chiral polar smectics is introduced with interactions up to the fourth neighboring layers. The minimization of the free energy gives three stable structur…
