Angular-momentum projection of cranked symmetry-unrestricted Slater determinants

We report on development of a new feature of the code HFODD, allowing for the angular-momentum projection of cranked symmetry-unrestricted Slater determinants. After a brief overview of the main theoretical building blocks and formalism, we present several preliminary applications. In particular, we discuss the case of a well-deformed rotational band in 156Gd, and we show the emergence of uncompensated poles in the overlap kernels calculated in an odd-A nucleus 155Eu.Comment: 9 pages, 5 figures, submitted to International Journal of Modern Physics

Symmetry energy in nuclear density functional theory

The nuclear symmetry energy represents a response to the neutron-proton asymmetry. In this survey we discuss various aspects of symmetry energy in the framework of nuclear density functional theory, considering both non-relativistic and relativistic self-consistent mean-field realizations side-by-side. Key observables pertaining to bulk nucleonic matter and finite nuclei are reviewed. Constraints on the symmetry energy and correlations between observables and symmetry-energy parameters, using statistical covariance analysis, are investigated. Perspectives for future work are outlined in the context of ongoing experimental efforts.Comment: 14 pages, 8 figures, submitted to the Special EPJA Issue on "Symmetry Energy
