Chiral Dynamics and Nuclear Matter
We calculate the equation of state of isospin-symmetric nuclear matter in the threeloop approximation of chiral perturbation theory. The contributions to the energy per particle Ē(kf ) from oneand two-pion exchange diagrams are ordered in powers of the Fermi momentum kf (modulo functions of kf/mπ). It is demonstrated that, already at orderO(k4 f ), two-pion exchange produces realistic nuclear b...
متن کاملChiral Dynamics in Nuclear Systems
A survey is given on selected topics concerning the role of spontaneous chiral symmetry breaking in low-energy QCD, and its dynamical implications for nuclear systems. This includes aspects of chiral thermodynamics (the temperature and density dependence of the chiral condensate). It also includes an update on the theory of low-energy (s-wave) pion-nuclear interactions relevant for deeply-bound...
متن کاملRecent Results in Chiral Nuclear Dynamics
Some recent developments in the description of nuclear forces and few-nucleon dynamics derived from chiral effective field theory are reviewed.
متن کاملNuclear pairing from chiral pion-nucleon dynamics
We use a recently improved version of the chiral nucleon-nucleon potential at next-to-next-toleading order to calculate the S0 pairing gap in isospin-symmetric nuclear matter. The pairing potential consists of the long-range oneand two-pion exchange terms and two short-distance NN-contact couplings. We find that the inclusion of the two-pion exchange at next-to-next-toleading order reduces subs...
