Description
Investigations of rare isotopes in the laboratory are opening
the way to understand and clarify the properties of all nuclei and bulk
nuclear matter. In this talk I will assess where we stand today in
solving the nuclear problem and how future rare isotope facilities will
impact our understanding of nuclei and our ability to predict nuclear properties in
stellar and other environments. The first part of the nuclear
problem concerns our ability to describe complex nuclei from the ground
up using as input the basic interactions among protons and neutrons. Indeed,
our community is on the verge of discovering how light nuclear systems
are built from bare nuclear interactions that have their roots in
QCD. I will describe this exciting frontier of research
through illustrating recent progress in the nuclear implementation of
coupled-cluster methods, a quantum many-body technique that enjoys great
success in quantum chemistry. After describing the basic coupled-cluster
ideas, I will illustrate their power by reporting on results of
ground- and excited state calculations for Oxygen and Calcium nuclei.
