Quantification of Uncertainties in Nuclear Density Functional Theory
Reliable predictions of nuclear properties are needed as much to answer fundamental science questions as to use in applications such as reactor physics or data evaluation. Nuclear density functional theory (DFT) is currently the only microscopic, global approach to nuclear structure that is applicable throughout the nuclear chart. In the past few years, considerable effort has been devoted to e...
متن کاملUncertainty Quantification and Propagation in Nuclear Density Functional Theory
Nuclear density functional theory (DFT) is one of the main theoretical tools used to study the properties of heavy and superheavy elements, or to describe the structure of nuclei far from stability. While on-going efforts seek to better root nuclear DFT in the theory of nuclear forces [see Duguet et al., this issue], energy functionals remain semi-phenomenological constructions that depend on a...
متن کاملError 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 ...
متن کاملNuclear 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...
متن کاملUncertainty quantification for nuclear density functional theory and information content of new measurements.
Statistical tools of uncertainty quantification can be used to assess the information content of measured observables with respect to present-day theoretical models, to estimate model errors and thereby improve predictive capability, to extrapolate beyond the regions reached by experiment, and to provide meaningful input to applications and planned measurements. To showcase new opportunities of...
