Starting from an analytically tractable two-emitter system, we identify the possible steady-state spatial arrangements accessible to the atoms. We then extend this analysis to larger ensembles in both linear and ring geometries. In linear chains, we demonstrate the emergence of topologically nontrivial dimerized configurations across a range of initial interatomic spacings. In ring geometries, we find that the system undergoes self-organized contraction and expansion, enabling access to length scales below those set by the trapping lattice. Our results demonstrate that collective light-matter interactions in free space can spontaneously generate modified ordered geometries, even when the emitters are initially separated by distances larger than their transition wavelength.
