Optical linewidth of a low density Fermi-Dirac gas
arXiv:cond-mat/9902172 · doi:10.1103/PhysRevLett.82.4741
Abstract
We study propagation of light in a Fermi-Dirac gas at zero temperature. We analytically obtain the leading density correction to the optical linewidth. This correction is a direct consequence of the quantum statistical correlations of atomic positions that modify the optical interactions between the atoms at small interatomic separations. The gas exhibits a dramatic line narrowing already at very low densities.
