The bare nucleon-nucleon interaction is essential for the production of pair correlations in nuclei, but an important contribution also arises from the induced interaction resulting from the exchange of collective vibrations between nucleons moving in time reversal states close to the Fermi energy. The pairing field resulting from the summed interaction is strongly peaked at the nuclear surface. It is possible to reproduce the detailed spatial dependence of this field by using either a local… 
Quasiparticle Renormalization and Pairing Correlations in Spherical Superfluid Nuclei
We present a detailed discussion of the solution of Nambu-Gor'kov equations in superfluid nuclei, which provide a consistent framework to deal with the interplay between particle-hole and particle-
Spatial dependence of the pairing field calculated with bare and induced interactions
The interaction induced by the exchange of low-lying surface vibrations between pairs of orbitals close to the Fermi surface provides an important contribution to pairing correlations in superfluid
Non-empirical pairing energy density functional
We perform systematic calculations of pairing gaps in semi-magic nuclei across the nuclear chart using the Energy Density Functional method and a non-empirical pairing functional derived, without
From bare to renormalized order parameter in gauge space : Structure and reactions
It is not physically obvious why one can calculate with similar accuracy, as compared to the experimental data, the absolute cross section associated with two-nucleon transfer processes between
Optimal pair density functional for the description of nuclei with large neutron excess
Toward a universal description of pairing properties in nuclei far from stability, we extend the energy density functional by enriching the isovector density dependence in the particle-particle
Chiral three-nucleon forces and pairing in nuclei
We present the first study of pairing in nuclei including three-nucleon forces. We perform systematic calculations of the odd–even mass staggering generated using a microscopic pairing interaction at
Spatial dependence of pairing in deformed nuclei
The solution of time-dependent Hartree-Fock-Bogoliubov equations by the Wignerfunction-moments method leads to the appearance of refined low-lying modes whose description requires the accurate
Localization of pairing correlations in nuclei within relativistic mean field models
We analyze the localization properties of two-body correlations induced by pairing in the framework of relativistic mean field (RMF) models. The spatial properties of two-body correlations are
RENORMALIZATION EFFECTS IN NUCLEI
Renormalization effects in nuclei, namely the calculation of the field theoretical processes which dress single-particle and collective degrees of freedom, lead to observable quantal states which
Semi-microscopic model for the effective pairing interaction in atomic nuclei
A model has been proposed in which the ab initio effective pairing interaction in atomic nuclei is supplemented by a small phenomenological term containing one parameter universal for all
