Unitary neutron matter in the on-shell limit Ruiz Arriola, Enrique Szpigel, S. Timóteo, V. S. Neutron matter Nucleon-nucleon interactions 37th Brazilian Meeting on Nuclear Physics. Sao Paulo (Brazil), 8-12 September 2014. 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 NN potentials. 2015-09-09T11:54:31Z 2015-09-09T11:54:31Z 2015 info:eu-repo/semantics/article Ruiz Arriola, E.; Szpigel, S.; Timóteo, V.S.
