The National Science Foundation (NSF) awarded a $270,000 Project Grant under the Mathematical and Physical Sciences (CFDA 47.049) program to the University of Tennessee to conduct research on the behavior of neutrinos in stellar supernova explosions and neutron star mergers. The project aims to establish a robust link between exact many-body and approximate mean-field calculations of the dominant neutrino flavor instabilities in these astrophysical environments. The research involves developing a many-body neutrino simulation framework using tensor network methods and comparing the results to state-of-the-art mean-field simulations. This work will help enhance our understanding of the origins of heavy elements in the universe and improve the modeling of neutrino processes in supercomputer simulations of astrophysical explosions. The award period is from Aug 1, 2024 to Jul 31, 2027, and the project will also involve mentoring students and hosting an international workshop to disseminate the research methods.
