Bi-layer-dimerized chiral liquid crystals

TL;DR

This paper develops a theoretical framework for bi-layered chiral liquid crystal phases, explaining differences between specific smectic A phases based on dipole moment pairing.

Contribution

It introduces a theory distinguishing bi-layered smectic phases by analyzing the presence or absence of dipole moment pairs.

Findings

Differentiates between SmC*_{A} and SmC_{α}* phases

Explains phase differences through dipole pairing mechanisms

Contributes to the theoretical understanding of bi-layered liquid crystals

Abstract

There is a large variety of bi-layered structures with smectic A type ordering. Results of this paper contribute to a theory of bi-layered phases. The difference between the \( SmC^{*}_{A} \) and \( SmC_{\alpha}^{*} \) phases is described in this latter paper and it is explained by existence and non-existence of the dipole moment pairs.
