TL;DR

This paper explores recent advances in chameleon models and proposes methods to detect these dark energy candidates through laboratory axion-like particle searches, including quantum vacuum experiments like GammeV.

Contribution

It introduces the concept of searching for chameleons in axion-like particle experiments and discusses their potential couplings to photons and matter.

Findings

Chameleons can be probed in laboratory axion-like particle searches.

Quantum vacuum experiments like GammeV could detect chameleon particles.

Chameleons may have different coupling strengths to photons and matter.

Abstract

We discuss some recent developments in chameleon models presented at the Fourth Patras workshop on Axions, WIMPs and WISPs. In particular we discuss the possibility of searching for chameleons in axion-like particle searches performed in the laboratory. Such chameleons may couple to both photons and matter with different coupling strengths. We discuss the exciting possibility of searching for these dark energy candidates in quantum vacuum experiments - in particular for the GammeV experiment at Fermilab.
