Renewed interest in the physics of nuclei is fueled by experiments at rare isotope beam facilities, which open the door to new regions of exotic nuclei; by astrophysical observations and simulations of neutron stars and supernovae, which require controlled extrapolations of the equation of state of nucleonic matter in density and isospin; and by studies of universal physics, which unite cold atom and dilute neutron physics. Progress on the nuclear many-body problem has long been hindered by the strong coupling between low- and high-energy states induced by typical nuclear Hamiltonians, which is manifested as highly correlated many-body wave functions and nonperturbative few and many-body systems. In this colloquium I describe how the interplay and coalescence of different threads: rapidly increasing computational power, effective field theory (EFT), and renormalization group (RG) transformations are enabling the development of new many-body methods and the revival of old ones to successfully attack these problems.
