ABHT(QMC-RMF1) unified crust
Abstract
This equation of state is a variant of the ABHT(QMC-RMF1) one with a crust reconstructed consistently with the CUTER tool [ DDFG_2024 , DDFG_2025], for details see [ DDFG_2025]. The core EoS is composed of homogeneous n, p, e-matter. It is computed using a relativistic mean-field theory constrained by chiral effective field theory calculations of pure neutron matter (from 0.08 /fm^3 to 0.32/ fm^3) and by properties of isospin-symmetric nuclear matter around saturation density [ ABHT_2022].
