The chiral atom waveguide is currently at the forefront of research on the directional
transmission of light. Researchers have explored the steady-state phases due to interaction-driven
events in this waveguide system. The interaction between atoms and photons gives rise to intriguing
phases defined by steady states. We conduct a theoretical investigation on the impact of varying
interatomic distances in driven atomic arrays that are coupled to a waveguide. An interesting study
involves examining the variation in distances between atoms and the detection of depletion processes
in different zones of the waveguide. This depletion affects the spatial distribution of atomic excitation
and its interaction with interface atoms in this phenomenon. Additionally, we will investigate the
interaction among all stages involved in this depletion event.
