TNTYST(KOST2) neutron matter
Abstract
Equation of state (EoS) based on the variational many-body theory with realistic nuclear forces for pure neutron matter is provided. For uniform matter, the EoS is constructed with the cluster variational method starting from the Argonne v18 two-body nuclear potential and the Urbana IX three-body nuclear potential. Non-uniform nuclear matter is treated in the Thomas-Fermi approximation. Alpha particle mixing is also taken into account, see [TNTSYT_17] for details.
