The system is modeled as an atomic beam diffracted by a periodic grating, whose transverse dynamics is described within the paraxial approximation. Environmental coupling is introduced through an effective open-system model that exponentially damps spatial coherences between diffracted components, allowing a continuous interpolation between the coherent Talbot regime and the incoherent far-field diffraction limit. Besides the usual intensity and transverse-momentum distributions, we ana"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"flux-channel structures can persist in parameter regimes where multi-slit interference features have already been strongly reduced.
