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...

Error Analysis in Nuclear Density Functional Theory

Nuclear density functional theory (DFT) is the only microscopic, global approach to the structure of atomic nuclei. It is used in numerous applications, from determining the limits of stability to gaining a deep understanding of the formation of elements in the universe or the mechanisms that power stars and reactors. The predictive power of the theory depends on the amount of physics embedded ...

Towards Density Functional Calculations from Nuclear Forces

We propose a method for microscopic calculations of nuclear groundstate properties in the framework of density functional theory (DFT). We discuss how the density functional is equivalent to the effective action for the density, thereby establishing a constructive framework for DFT calculations from nuclear forces. The presented approach starts from non-interacting nucleons in a background pote...

Scalar nature of the nuclear density functional

Because of the rotational invariance of the nuclear Hamiltonian, there exists a density functional (DF) for nuclei that depends only on two scalar densities. Practical calculations boil down to radial, one-dimensional ones. Let Z,N,A ≡ Z+N be the proton, neutron and mass numbers, respectively. The nuclear HamiltonianH is known to be invariant under rotations. Therefore, besides Z and N, nuclear...

Nuclear fission in covariant density functional theory

The current status of the application of covariant density functional theory to microscopic description of nuclear fission with main emphasis on superheavy nuclei (SHN) is reviewed. The softness of SHN in the triaxial plane leads to an emergence of several competing fission pathes in the region of the inner fission barrier in some of these nuclei. The outer fission barriers of SHN are considera...
