Pairing Gaps from Nuclear Mean–Field Models
We discuss the pairing gap, a measure for nuclear pairing correlations, in chains of spherical, semi–magic nuclei in the framework of self–consistent nuclear mean–field models. The equations for the conventional BCS model and the approximate projection–before–variation Lipkin–Nogami method are formulated in terms of local density functionals for the effective interaction. We calculate the Lipki...
متن کاملNuclear mean field from chiral pion-nucleon dynamics
Using the two-loop approximation of chiral perturbation theory, we calculate the momentum and density dependent single particle potential of nucleons in isospin-symmetric nuclear matter. The contributions from oneand two-pion exchange diagrams give rise to a potential depth for a nucleon at rest of U(0, kf0) = −53.2MeV at saturation density. The momentum dependence of the real part of the singl...
متن کاملDynamic mean-field models from a nonequilibrium thermodynamics perspective.
Complicated dynamic models are often approximated by introducing mean-field approximations and closures. The focus here is on examining such mean-field models using nonequilibrium thermodynamics. Two illustrative examples are studied in terms of the double-generator general equation for the nonequilibrium reversible-irreversible coupling (GENERIC) framework. First, it is shown that a model for ...
متن کاملEquation of state of isospin-asymmetric nuclear matter in relativistic mean-field models with chiral limits
Using in-medium hadron properties according to the Brown-Rho scaling due to the chiral symmetry restoration at high densities and considering naturalness of the coupling constants, we have newly constructed several relativistic mean-field Lagrangians with chiral limits. The model parameters are adjusted such that the symmetric part of the resulting equation of state at supra-normal densities is...
