Robust Coherent Transport of Light in Multilevel Hot Atomic Vapors

Phys Rev Lett. 2019 May 10;122(18):183203. doi: 10.1103/PhysRevLett.122.183203.

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.
