The Canonical Nuclear Many-Body Problem as an Effective Theory
Recently it was argued that it might be possible to treat the conventional nuclear structure problem – nonrelativistic point nucleons interacting through a static and rather singular potential – as an effective theory in a shell-model basis. In the first half of this talk we describe how such a program can be carried out for the simplest nuclei, the deuteron and He, exploiting a new numerical t...

متن کاملRecent Developments in the Nuclear Many-body Problem
The study of quantum chromodynamics (QCD) over the past quarter century has had relatively little impact on the traditional approach to the low-energy nuclear many-body problem. Recent developments are changing this situation. New experimental capabilities and theoretical approaches are opening windows into the richness of many-body phenomena in QCD. A common theme is the use of effective field...
متن کاملRole of Chiral Symmetry in the Nuclear Many-Body Problem
The role of chiral (pion) dynamics in nuclear matter is reviewed. Contributions to the energy per particle from oneand two-pion exchange are calculated systematically, and it is demonstrated that already at order k f in the Fermi momentum, two-pion exchange produces realistic nuclear binding together with very reasonable values for the compressibility and the asymmetry energy. Further implicati...
متن کاملThe Canonical Nuclear Many-body Problem as a Rigorous Effective Theory
The shell model is the standard tool for addressing the canonical nuclear manybody problem of nonrelativistic nucleons interacting through a static potential. We discuss several of the uncontrolled approximations that are made in this model to motivate a different approach, one based on an exact solution of the BlochHorowitz equation. We argue that the necessary self-consistent solutions of thi...
