Abstract

Pairing correlations in nuclear systems have a long and rich history. They are an effect suggested more that a half-century ago and they are still related to a sizeable part of theoretical and experimental nuclear structure and dynamics investigations, while their relevance to the properties of neutron stars make nuclear superfluids an important concept in neutron star structure studies. In this  thesis, we present various phenomenological investigation of nuclear superfluidity. We prescribe a modern way of solving the mean-field equations of pairing, holding the promise of out-performing standard approaches. On a different front, we complement novel microscopic descriptions of neutron pairing by extracting error estimations in systematic ways. Finally, we are probing novel nuclear superfluids, such as spin-triplet or mixed-spin pairs in nucleon-``emulating'' cold atoms and in nuclei. For the latter, we identify the behavior of various pairing condensates under realistic nuclear deformation, bringing results closer to experiment.
