Pairing Correlations in Nuclear Systems, from Neutron Stars to Finite Nuclei

Abstract

In this contribution we attempt at giving an overview of pairing correlations in nuclear systems with an emphasis on Superfluidity and superconductivity in neutron stars and the relation to the underlying nucleon-nucleon interaction. Extraction and interpretations of pairing correlations in finite nuclei through large-scale shell model studies of nuclei with mass A ∼ 100 - 132. Effective interactions based on recent nucleon-nucleon interactions are utilized in the shell-model studies. The partial waves which lead to superfluid properties in infinite matter are also crucial for pairing correlations in finite nuclei. Discussion of recent experimental and theoretical studies of thermodynamical properties of finite nuclei and their interpretation in terms of eventual pairing transitions in finite nuclei.
