Nuclear Pairing from Two-body Microscopic Forces: Analysis of the Cooper Pair Wavefunctions

Abstract

In a recent paper we studied the behavior of the pairing gaps $Δ_F$ as a function of the Fermi momentum $k_F$ for neutron and nuclear matter in all relevant angular momentum channels where superfluidity is believed to naturally emerge. The calculations employed realistic chiral nucleon-nucleon potentials with the inclusion of three-body forces and self-energy effects. In this contribution, after a detailed description of the numerical method we employed in the solution of the BCS equations, we will show a preliminary analysis of the Cooper pair wavefunctions.
