Large scale tabulated neutrino opacity table for next-generation simulations of core-collapse supernovae/binary neutron star mergers

The neutrino opacities of hot and dense matter play an important role in the core collapse supernovae (CCSNe) explosion mechanism, the nucleosynthesis process in CCSNe and binary neutron star (BNS) mergers, and the fast neutrino flavor conversions. The neutrino-nucleon interactions are one of the main sources of neutrino opacities. An accrate discription of massive star neutrino opacities requires one to take into account both the many-body corrections in dense matter and the kinematics constraints of neutrino-nucleon reactions in an extremely wide range of densities, temperatures, proton fractions and incoming neutrino energies. This has not been fully achieved in the state-of-the-art numerical simulations of CCSNe and BNS merger. In this talk, I would like to introduce our work on constructing large scale tabulated neutrino opacity table for next-generation simulations of core-collapse supernovae/binary neutron star mergers, which applies random phase approximations that consistent with underlying equation of states to estimate the many-body corrections on neutrino-nucleon opacities. I will also discuss the uncertainties and the possible experimental constraints for neutrino opacities in different regions (densities, temperatures, proton fractions) of our table.
