  Atoms coupled to nanophotonic interfaces represent an exciting frontier for
the investigation of quantum light-matter interactions. While most work has
considered the interaction between statically positioned atoms and light, here
we demonstrate that a wealth of phenomena can arise from the self-consistent
interaction between atomic internal states, optical scattering, and atomic
forces. We consider in detail the case of atoms coupled to a one-dimensional
nanophotonic waveguide, and show that this interplay gives rise to
self-organization of atomic positions along the waveguide, which can be probed
experimentally through distinct characteristics of the reflection and
transmission spectra.
