FRIB-TA Supported Scientists

The FRIB Theory Alliance supports young scientists through the FRIB Bridge Faculty program and the National FRIB Theory Fellow program.

Current Theory Bridge Faculty

Prof. Sebastian König, North Carolina State University   [skoenig@ncsu.edu]   start date: 1/2020

Dr. König's research has centered around exploring the powerful tool of effective field theories in low energy nuclear theory. In addition, he is developing new methods for nuclear structure for a wide range of masses, as well as developments that work toward the unification of structure and reactions. These are important in the interpretation of a wide range of phenomena that FRIB will cover.

Prof. Saori Pastore, Washington University   [saori@wustl.edu]   start date: 8/2018

Understanding the fundamental interactions in nature and their symmetries is at the heart of the research being developed by Dr. Pastore. She explores the effect of weak interactions in nuclei, using Quantum Monte Carlo techniques to determine nuclear structure, and in particular beta-decays and weak transition matrix elements. Her research connects strongly with the fundamental symmetries program planned for FRIB.

Prof. Maria Piarulli, Washington University   [mpiarulli@physics.wustl.edu]   start date: 8/2018

The nuclear force is the essential building block for ab-initio theories of the nucleus. Dr. Piarulli has been working with collaborators on the formulation of the nuclear force (and associated currents) for use in quantum Monte Carlo (QMC) calculations of nuclear structure and reactions. Although she is mostly involved in ab-initio calculations for light nuclei, these can provide important benchmarks to test other computational methods applicable to heavy nuclei, where the treatment of nuclear interactions and currents is much less controlled. For this reason, Dr. Piarulli's work is relevant to a large fraction of FRIB's scientific programs.

Current Theory Fellows

Dr. Kevin Fossez, hosted by ANL   [fossez@nscl.msu.edu]   start date: 3/2019

The research developed by Dr. Fossez explores the most exotic nuclei ever created. Fossez works on the unification of nuclear structure and reactions. This problem can be addressed either by extending ab-initio capabilities to continuum states, to increase predictive power in unknown regions of the nuclear chart, or by developing novel and more precise approaches at lower energy that take into account the existence of emergent phenomena in nuclei while still being properly connected with the more fundamental levels of description.

Dr. Diego Lonardoni, hosted by LANL   [lonardoni@nscl.msu.edu]   start date: 10/2015

The research carried out by Dr. Lonardoni contributes to building a predictive understanding of nuclear systems characterized by high neutron-to-proton imbalance, from neutron-rich nuclei to neutron stars, grounded in high-quality nuclear forces and ab-initio theory, including a complete assessment of all uncertainties associated with a nuclear many-body calculation. His results have impact on several FRIB experimental programs as well as other U.S. national laboratories.

Past Theory Fellows

Dr. Gregory Potel Aguilar, LLNL   [potelaguilar1@llnl.gov]
   FRIB-TA Fellow at MSU, 2016-2019

Dr. Potel’s research is in reaction theory and in particular reactions involving deuterons. Deuteron-induced transfer reactions are a popular tool in nuclear physics and recent applications of this probe have included exploring the structure of exotic isotopes and using them as an indirect tool for neutron capture processes. This is the context of Potel's work, which tightly connects with many FRIB experimental programs.
