Isospin-Asymmetry Dependence of the Thermodynamic Nuclear Equation of State

The equation of state (EoS) of hot and dense neutron-rich nuclear matter is an essential quantity in nuclear astrophysics and governs the properties of neutron stars and core-collapse supernovae. In this talk, we discuss computations of the thermodynamic nuclear EoS in many-body perturbation theory (MBPT) using nuclear two- and three-body interactions derived from chiral effective field theory. We show that the proper generalization of MBPT to finite temperatures amounts to a nontrivial reorganization of the standard linked-cluster expansion for the free energy in terms of a Legendre transformation of truncated correlation functions. Using this framework, we then investigate in detail the isospin-asymmetry dependence of the EoS at different densities and temperatures. Finally, we discuss future research efforts that are headed towards the construction of a chiral nuclear EoS for astrophysical applications.
