Unitary neutron matter in the on-shell limit
Enrique Ruiz Arriola · Sergio Szpigel · Varese Salvador Timoteo
Abstract
We compute the Bertsch parameter for neutron matter by using nucleon-nucleon interactions that are fully diagonal in momentum space. We analyze the on-shell limit with the similarity renormalization group and compare the results for a simple separable toy model to realistic calculations with high precision potentials.
