  "abstract": "First-principles calculations of scattering off quantum many-body systems such as atoms and nuclei is important but nontrivial, requiring large-dimension ($10^3$ to $10^8$ or more) bases. For the first time we apply to many-body targets a recently developed approach to find phase shifts in $L^2$-integrable bases, computing neutron-nucleus scattering using the same interactions as ab initio models of nuclei, in very small (dimension 3-6) bases. Our work shows the mean field dominates low-energy nuclear scattering; it also provides a foundation for more efficient future methodologies.",
