About the NextG-DFT project

Project summary

The theoretical framework of the Density Functional Theory (DFT), one of the most popular and successful ab initio approaches to the structure of quantum many-body systems - atoms, molecules, solids will be extended and applied to equilibrium and decay properties of nuclei away from the stability line.

The principal goal of this project is the formulation, modeling and application of a controlled ladder of approximations for the most important ingredient of a nuclear EDF - the exchange-correlation functional. The resulting semi-empirical EDF will be used to describe phenomena related to the evolution of shell structures in medium-heavy and heavy nuclei far from stability, and to investigate the island of stability and structure properties of superheavy nuclei. For spectroscopic applications the EDF framework will be extended to include collective correlations related to symmetry restoration and fluctuations of collective variables. A fully microscopic, EDF-based, collective Hamiltonian model for quadrupole degrees of freedom will be developed and implemented. Accurate and efficient computational algorithms will be devised, and studies of shape coexistence phenomena and quantum shape/phase transitions performed. This framework will also be employed in a microscopic investigation of ground- and excited-state properties of superheavy nuclei that form the mass and charge boundary of stability of the periodic table.
