The transport properties of neutron matter in the LOCV channel dependent effective two-body interactions framework

The channel dependent effective two-body interactions (CDEI) which are generated through the lowest order constrained variational (LOCV) method for pure neutron matter (PNM) are used to calculate the in-medium neutron-neutron (nn) cross-sections and transport properties of PNM within the Landau-Abrikosov-Khalatnikov (LAK) formalism. Similar to our previous work, the Reid68, Δ-Reid68, and Av18 interactions as well as the V6′ potential are considered as the input bare nucleon-nucleon phenomenological potentials. In present work, we improve our previous results by calculating the shear viscosity and thermal conductivity of PNM in the framework of LOCV CDEI and the comparisons are made with those coming from the channel independent calculations, i.e. the averaged effective interactions (AEI) results. It is shown that our new results are in a good agreement with the other approaches. It is also demonstrated that, the choice of in-medium effective interaction has a crucial role in the resulting nn cross-section as well as the transport properties of PNM.
