Corrections to standard expressions for the interparticle potentials are obtained through computer algebra system strategies and a novel heuristic argument for comparison with field theory computations. It is confirmed that, to first order in the deformation parameter, the unretarded (c ->infinity) van der Waals potential is unchanged. The modified retarded Casimir-Polder potential, obtained from the minimal length zero-point field, compares satisfactorily in both sign and magnitude with rigorous calculations. It is shown that low energy neutron scattering can provide a gain in excess of 18 orders of magnitude over atomic physics experiments in constraining corrections due to the existence of a minimal length.eninfo:eu-repo/semantics/closedAccessDispersion forces in minimal length theoriesquantum gravityneutron-neutron scatteringQuantum ScatteringGravityArticle10.1142/S02182718204302692-s2.0-85095843477
