Query: Near-resonant light transmission in two-dimensional dense cold atomic
  media with short-range positional correlations   Light propagation in disordered media is a fundamental and important problem
in optics and photonics. In particular, engineering light-matter interaction in
disordered cold atomic ensembles is one of the central topics in modern quantum
and atomic optics. The collective response of dense atomic gases under light
excitation, which crucially depends on the spatial distribution of atoms and
the geometry of the ensemble, has important impacts on quantum technologies
like quantum sensors, atomic clocks and quantum information storage. Here we
analyze near-resonant light transmission in two-dimensional dense ultracold
atomic ensembles with short-range positional correlations. Based on the
coupled-dipole simulations under different atom number densities and
correlation lengths, we show that the collective effects are strongly
influenced by those positional correlations, manifested as significant shifts
and broadening or narrowing of transmission resonance lines. The results show
that mean-field theories like Lorentz-Lorenz relation are not capable of
describing such collective effects. We further investigate the statistical
distribution of eigenstates, which are significantly affected by the interplay
between dipole-dipole interactions and position correlations. This work can
provide profound implications on collective and cooperative effects in cold
atomic ensembles as well as the study of mesoscopic physics concerning light
transport in strongly scattering disordered media.
