N2 - We present ab initio calculations for H3, He4, O16, and Ca40 based on two-nucleon low-momentum interactions Vlowk within coupled-cluster theory. For H3 and He4, our results are within 70 and 10 keV of the corresponding Faddeev and Faddeev-Yakubovsky energies. We study in detail the convergence with respect to the size of the model space and the single-particle basis. For the heavier nuclei, we report practically converged binding energies and compare with other approaches.
