# Surface Anchoring Energy of Cholesteric Liquid Crystals

## TL;DR

This paper introduces a new surface energy expression for cholesteric liquid crystals, revealing a previously unaccounted symmetry-allowed term that impacts surface anchoring behavior.

## Contribution

It proposes a novel surface energy formulation for cholesteric liquid crystals, including a new symmetry-allowed term absent in traditional models.

## Key findings

- Identification of a new symmetry-allowed surface energy term
- Implications for surface anchoring behavior in cholesteric liquid crystals
- Discussion of consequences of the new surface energy expression

## Abstract

In this paper, we propose a suitable surface energy expression for cholesteric liquid crystals. We show that there exists a symmetry allowed term for chiral nematics that doesn't appear in the traditional Rapini-Papoular surface energy form. We discuss some consequences of this new surface anchoring term.
