In a tight spot, spin and charge separate

TL;DR

This paper explores how photons in a hollow waveguide with atomic gas can exhibit spin-charge separation, a phenomenon typically seen in one-dimensional fermionic systems.

Contribution

It proposes a novel way to observe spin-charge separation in photonic systems, bridging concepts between bosonic photons and fermionic behaviors.

Findings

Photons can exhibit spin-charge separation in specific waveguide setups.

Atomic gases enable the emergence of fermion-like behavior in photons.

Potential for new quantum simulation platforms.

Abstract

Photons (bosons) confined in a hollow waveguide containing an atomic gas could show spin-charge separation, which is more commonly associated with one-dimensional fermions.
