Abstract
We introduce NuLattice, a Python software package for ab initio computations of atomic nuclei on lattices. The computational tools consist of Hartree Fock, the coupled cluster method, the in-medium similarity renormalization group, and full configuration interaction. At present, the employed interactions are from pion-less effective field theory at leading order and consist of two-body and three-body contacts. We present results for light nuclei H, He, Be, C, and O. NuLattice algorithms exploit the sparsity and locality of lattice interactions, and as a result computations can be run on laptops.
