Advances in nuclear matter based on chiral effective field theory^⋆ — •Arianna Carbone — TU Darmstadt, Darmstadt, Germany

In recent years, great progress has been made in nuclear matter calculations at zero and finite temperature based on chiral two- and three-nucleon interactions. This is critical for understanding matter in neutron stars and for providing a reliable equation of state for core-collapse supernovae and neutron star mergers. In addition, the properties of nuclear matter, such as the symmetry energy, can constrain density functionals and global predictions of nuclei. In this talk, I will discuss recent advances in ab initio calculations using chiral effective field theory interactions, highlighting the role of three-nucleon forces for predicting realistic nuclear matter properties. In addition, I will discuss the theoretical uncertainties, how they can be improved in the future, and show how reliable nuclear theory constrains matter under astrophysical conditions.
