# Robust coherent transport of light in multi-level hot atomic vapors

## TL;DR

This paper demonstrates that coherent light transport remains robust in hot atomic vapors despite Doppler effects, revealing interference effects from hyperfine transitions in a linear, far-detuned scattering regime.

## Contribution

It provides both experimental and theoretical evidence that coherence persists in hot vapors and uncovers interference phenomena involving hyperfine transitions under specific scattering conditions.

## Key findings

- Coherent scattering is robust despite Doppler broadening.
- Interference from inelastic hyperfine transitions emerges in far-detuned regimes.
- Experimental and theoretical results align well.

## Abstract

Using a model system, we demonstrate both experimentally and theoretically that coherent scattering of light can be robust in hot atomic vapors despite a significant Doppler effect. By operating in a linear regime of far-detuned light scattering, we also unveil the emergence of interference triggered by inelastic Stokes and anti-Stokes transitions involving the atomic hyperfine structure.
