Low Scale Saturation of Effective NN Interactions and Their Symmetries
The Skyrme force parameters can be uniquely determined by coarse graining the Nucleon-Nucleon (NN) interactions at a characteristic momentum scale. We show how exact Vlowk potentials to second order in momenta are saturated with physical NN scattering threshold parameters at Center of Mass (CM) cut-off scales of about Λ = 250 MeV for the S-waves and Λ = 100 MeV for the P-waves. The pattern of W...
متن کاملNuclear Structure and Response based on Correlated Realistic NN Interactions
Starting from the Argonne V18 nucleon-nucleon interaction and using the Unitary Correlation Operator Method, a correlated interaction vUCOM has been constructed, which is suitable for calculations within restricted Hilbert spaces. In this work we employ the vUCOM in Hartree-Fock, perturbation-theory and RPA calculations and we study the ground-state properties of various closed-shell nuclei, as...
متن کاملRPA and ERPA with Correlated Realistic NN Interactions
The Unitary Correlation Operator Method (UCOM) provides a powerful scheme for carrying out ab initio nuclear structure calculations [1, 2, 3, 4]. In particular, it makes it possible to combine numerically affordable manybody Hilbert spaces with modern realistic NN interactions. Short-range correlations are explicitly taken into account. First results ranging from no-core shell model to HartreeF...
متن کاملAb Initio Nuclear Structure Theory with Chiral NN+3N Interactions
Low-energy nuclear theory has entered an era of ab initio nuclear structure and reaction calculations based on QCD. One of the most promising paths from QCD to nuclear observables employs Hamiltonians constructed within chiral effective field theory as starting point for precise ab initio studies. However, the full inclusion of chiral twoplus three-nucleon (NN+3N) interactions in exact and appr...
