Abstract:
|
Nuclear Energy Density Functional (EDF) theory has been invaluable in understanding the properties of nuclei and their impact on applications from stellar phenomena to energy applications. Numerical implementations of EDF models are able to simulate the properties of elements across the nuclide table. The simulated outputs can be compared to physical observations to both constrain uncertainty about parameters of EDF models and to understand the structure in physical data that the models are unable to capture. This talk will present work on calibration of the model and analysis of a structured discrepancy model with the goal of improving the ability to extrapolate to new nuclei properties beyond the observed and further understanding of the ways in which the simulator can be improved.
