Query: Finite volume effects in low-energy neutron-deuteron scattering   We present a lattice calculation of neutron-deuteron scattering at very low
energies and investigate in detail the impact of the topological finite-volume
corrections. Our calculations are carried out in the framework of pionless
effective field theory at leading order in the low-energy expansion. Using
lattice sizes and a lattice spacing comparable to those employed in nuclear
lattice simulations, we find that the topological volume corrections must be
taken into account in order to obtain correct results for the neutron-proton
S-wave scattering lengths.
