  In the past decade, coupled-cluster theory has seen a renaissance in nuclear
physics, with computations of neutron-rich and medium-mass nuclei. The method
is efficient for nuclei with product-state references, and it describes many
aspects of weakly bound and unbound nuclei. This report reviews the technical
and conceptual developments of this method in nuclear physics, and the results
of coupled-cluster calculations for nucleonic matter, and for exotic isotopes
of helium, oxygen, calcium, and some of their neighbors.
