Investigation of rare nuclear isotopes becomes the most fascinating topic in the low-energy nuclear physics. Such studies, besides improving the understanding of fundamental interactions, facilitate applications with direct societal impact, including those in medicine, hmeland security, and industry. The advent of experimental facilities with beams of unstable atomic nuclei opens up new opportunities in this area of research, such as astrophysical applications for predicting the evolution of stars and galaxies. In this context nuclear theory is engaged to provide missing information about exotic nuclei that is not accessible experimentally. To this effort the project will contribute an implementation of novel ideas on nuclear structure, which will be benchmarked against state-of-the-art experimental data. Training graduate students by engaging them in this research and launching their careers in academia and industry are important components of the project. The novel results will be employed in upgrading the relevant graduate courses, aiming at attracting young talents to the field of nuclear physics.
This project addresses fundamental theoretical questions about microscopic mechanisms of emergent collectivity in many-body quantum systems. The new theoretical method will be developed to derive the collective effects from the underlying nuclear forces. The method will be implemented numerically for the description of nuclear spectra studied at major nuclear physics facilities, such as the National Superconducting Cyclotron Laboratory (NSCL) / Facility for Rare Isotope Beams (FRIB) at Michigan State University and the Institute of Physical and Chemical Research (RIKEN) in Tokyo. Burning issues in the description of nuclear masses and radii will be addressed as well. Upon benchmarking to data, the implementations will be extended to finite temperatures to model the behavior of medium-mass nuclei in stellar environments. This will allow one to obtain a high-quality description of the nuclear reaction rates, which serve as an input for astrophysical modeling of neutron star mergers and supernova explosions. Part of the project will be devoted to quantum computation of prototype systems and search for efficient quantum-classical algorithms for computing atomic nuclei.
This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

Challenges and recent progress of the nuclear many-body problem on the fermionic correlation functions (CFs) are reviewed. Starting from the ab-initio Hamiltonian, a consistent equation of motion (EOM) framework is formulated for the low-rank CFs and adopted for nuclear applications by approximations with minimal truncations, which keep the leading effects of emergent collectivity. A mapping of the EOM approach to the relativistic nuclear field theory (RNFT) allows for extending the RNFT to higher configuration complexity. The latter is implemented numerically for the nuclear response, on the basis of the relativistic effective meson-nucleon Lagrangian. The results obtained for medium-heavy nuclei show that the inclusion of higher-complexity configurations with the emergent collective degrees of freedom improves considerably the description of both gross and fine details of the nuclear spectra, in both the high-energy and the low-energy sectors. The connection between the configuration complexity and the accuracy of the resulting excitation spectra is analyzed in terms of the solvable Lipkin Hamiltonian with a simple tunable interaction. Quantum simulations of few-particle systems are invoked to evaluate the prospects of quantum computation for atomic nuclei. Perspectives of the finite-temperature RNFT to generate input for the kilonova and supernova models are outlined.

Congratulations to Herlik Wibowo with receiving the Travel Grant from the Division of Nuclear Physics (DNP) of the American Physical Society (APS)!
This Grant will sponsor the travel to the 2019 APS April Meeting in Denver CO, April 13 - 16, 2019.
A gallery of photographs on acrylic glass was a part of the FRIB and NSCL open house on August 18, 2018. The gallery features fine-art photography of Olga Pechenova (GSI Helmholtzzentrum für Schwerionenforshung, Darmstadt, Germany). The collection entitled “Layers of Reality” is composed in collaboration with Elena Litvinova (Western Michigan University) and sponsored by Litvinova’s NSF Career grant. Two of the art-works are co-authored with Oleksiy Dolinskyy (GSI, painting). The presented composition shows metaphorical connections between different aspects of reality perceived through the concepts of modern physics. It aims at providing a deeper understanding of the world around us by exposing surprising and surreal aspects of colors and shapes, metaphors and symbols, nature and human beings. The unique combination of scientific knowledge and intuition with the author’s artistic vision reveals angles and layers of comprehension of deeply related metaphysical categories, such as space and time, symmetries and scales, matter and geometry, universe and multiverse. The exhibition will remain in NSCL in the fall 2018.
Many thanks to Dieter Ackermann, Manuel Bautista, Alex Brown, Dean Halderson, Kirk Korista, Lori Krum, Sean Liddick, Vladimir Pechenov, and Herlik Wibowo for cooperation!

NSF CAREER Award # 1654379: The project addresses fundamental theoretical questions about the microscopic mechanisms responsible for the binding of loosely-bound nuclei, nuclear shapes and decay properties, and for spectra of nuclear excitations. The project emphasizes the geometrical aspects of nuclear dynamics: intrinsic deformations, coupling to the continuum, and shapes and spatial density distributions associated with nuclear excitations and superfluidity. The developed approaches will account for emergent collective phenomena in medium-mass and heavy nuclei with higher accuracy and predictive power that are crucial for various applications. Comparison to results of recent and future experiments at major nuclear physics facilities, such as NSCL/FRIB and RIKEN, will constrain both the underlying nuclear forces and the many-body coupling mechanisms included in the theory.
