Hybrid quark–hadron equation of state DD2f–SFM1.1: three-dimensional tables for astrophysical simulations

Tabulated equation of state (EoS) of hybrid quark–hadron matter on a three-dimensional grid in temperature, baryon number density and charge fraction, in the format used by core-collapse supernova and neutron-star merger codes. The hadronic phase is the DD2f relativistic density functional with a nuclear statistical equilibrium description of nuclei based on FRDM mass tables; the quark phase is the SFM1.1 quark-matter density functional. Three variants of the deconfinement transition are provided: a Maxwell construction and two replacement-interpolation constructions with different pressure offsets.Funding:This research is part of the project No. 2021/43/P/ST2/03319 co-funded by the National Science Centre and the European Union Framework Programme for Research and Innovation Horizon 2020 under the Marie Skłodowska-Curie grant agreement No. 945339.
