Testing Chameleon models in the laboratory

TL;DR

This paper reviews recent developments in chameleon models, focusing on their couplings to photons and matter, and explores laboratory experiments to test the chameleon-photon interaction.

Contribution

It introduces the concept of chameleon models coupling differently to photons and matter and discusses experimental approaches to probe these couplings in laboratory settings.

Findings

Chameleon models can have distinct couplings to photons and baryonic matter.

Laboratory quantum vacuum experiments can potentially detect chameleon-photon interactions.

Theoretical frameworks for testing chameleon models in controlled experiments are discussed.

Abstract

We review some recent developments in chameleon models. In particular we discuss the possibility of chameleons coupling both to photons and baryonic matter with different coupling strengths. We will discuss the possibility of probing the chameleon-photon coupling with quantum vacuum experiments in the laboratory.
