Query: Directional transport along an atomic chain   Motivated by a recent prediction to engineer the dispersion relation of a
waveguide constructed from atomic components [arXiv:2104.08121], we explore the
possibility to create directional transport in an open, collective quantum
system. The optical response of the atomic waveguide is characterized through a
scattering-matrix formalism built upon theories of photoelectric detection that
allows us to find the required conditions for directional mode-to-mode
transmission to occur and be measured in an experimental setting. We find that
directional waveguides allow for an efficient outcoupling of light by reducing
backscattering channels at the edges. This reduced backscattering is seen to
play a major role on the dynamics when disorder is included numerically. A
directional waveguide is shown to be more robust to localization, but at the
cost of increased radiative losses.
