# Entanglement, squeezing and state-swap in cholesteric liquid crystals

## TL;DR

This paper demonstrates that quantum-like phenomena such as entanglement, squeezing, and state-swap can occur in cholesteric liquid crystals under a magnetic field, expanding the understanding of these effects beyond traditional quantum systems.

## Contribution

It reveals that classical cholesteric liquid crystals can exhibit quantum-like effects, providing new insights into their behavior and potential applications.

## Key findings

- Entanglement and squeezing observed in liquid crystals
- Conditions for observing quantum-like effects analyzed
- Potential for classical systems to mimic quantum phenomena

## Abstract

Phenomena such as state-swap, quadrature squeezing, entanglement and violation of entanglement inequalities are frequently reported to occur in quantum systems only. It is shown here that these effects can also occur in cholesteric liquid crystals in the presence of an applied magnetic field. The nature of these effects as well as the conditions for their observation are analysed.
