Nuclear energy density functional from chiral pion-nucleon dynamics
We calculate the nuclear energy density functional relevant for N=Z even-even nuclei in the systematic framework of chiral perturbation theory. The calculation includes the onepion exchange Fock diagram and the iterated one-pion exchange Hartree and Fock diagrams. From these few leading order contributions in the small momentum expansion one obtains already a very good equation of state of isos...
متن کاملNuclear Density Functional Constrained by Low-energy Qcd *
We have developed a relativistic point-coupling model of nuclear many-body dynamics constrained by the low-energy sector of QCD. The effective Lagrangian is characterized by density-dependent coupling strengths determined by chiral one-and two-pion exchange (with single and double delta isobar excitations) and by large isoscalar background fields that arise through changes of the quark conden-s...
متن کاملTesting the kinetic energy functional : Kinetic energy density as a density functional
A new method for defining an energy density for the noninteracting kinetic energy of density functional theory is given. The resulting energy density is a density functional determined completely by the kinetic energy functional itself. Although this method is not constructive, it allows for a direct comparison between exact and approximate functionals pointwise in space. For simple systems, th...
متن کاملFe b 20 06 Relativistic nuclear energy density functional constrained by low - energy QCD ⋆
A relativistic nuclear energy density functional is developed, guided by two important features that establish connections with chiral dynamics and the symmetry breaking pattern of low-energy QCD: a) strong scalar and vector fields related to inmedium changes of QCD vacuum condensates; b) the longand intermediate-range interactions generated by one-and two-pion exchange, derived from in-medium ...
