We discuss computational aspects of the spherical coupled-cluster method specific to the nuclear many-body problem. Using chiral nucleon-nucleon interaction at next-to-next-to-next-to leading order (N3LO) with cutoff Lambda = 500MeV, we present coupled-cluster results for the ground state of 40Ca. Scaling and performance studies are presented together with challenges we meet with when extending the coupled-cluster effort to nuclei mass hundred and beyond.

IMSRG(3)-N7 calculations for calcium-44, -48, and -52 show that three-body flow corrections substantially lower the 48Ca 2+ energy, improving the description of the N=28 shell closure, while leaving the 52Ca charge-ra...
