We present lattice results for the ground state energies of tritium,
helium-3, helium-4, lithium-6, and carbon-12 nuclei. Our analysis includes
isospin-breaking, Coulomb effects, and interactions up to
next-to-next-to-leading order in chiral effective field theory.Comment: 4 pages, 4 figures, published version to appear in Phys. Rev. Lett
