Effective interactions and pairing correlations: from nuclei to compact stars
… on the impact of some relevant interparticle correlations, mainly active in the low density region of the phase diagram, which occur in fermionic system and are responsible for the superfluid phenomena: the pairing correlations. Our goal is therefore to examine the interplay of these …

Group theoretical approach to pairing and non-linear phenomena in atomic nuclei
… studying proton-neutron (pn) and like-nucleon pairing correlations as well as higher-J pn interactions in nuclei when protons and neutrons occupy the same shell. While these correlations manifest themselves most clearly in the binding energies of 0+ ground states, they also have a large effect …

Dynamical pairing states in cold gases
In this thesis, we study dynamical pairing of fermions caused by the time-dependent interaction. Fermionic pairing develops on time scales short compared to the quasiparticle relaxation time where existing approaches to the problem including the Boltzmann kinetic equation and time-dependent …

Unconventional Fermi surface in insulating SmB6 and superconducting YBa2Cu3O6+x probed by high magnetic fields
… gapped out by a strong order parameter involving pairing correlations, potentially in addition to the other order parameters. Transport measurements performed over a wide doping range show signatures consistent with pairing correlations that persist up to the pseudogap temperature $T^*$. The …

MICROSCOPIC THEORY OF INFINITE NUCLEAR MATTER AND NON-EMPIRICAL ENERGY FUNCTIONALS
… (ADC-SCGF) is developed to include Gorkov pairing correlations. The ab initio equations of state (EOS) are used to construct EDFs based on the local density approximation and gradient approximation, which are applied to magic nuclei. Then, the static response of nuclear matter is tackled …

Pairing and superfluidity in strongly interacting Fermi gases
… Chandrasekhar-Clogston limit of superfluidity. Pairing correlations in the superfluid and normal phase are studied with radio-frequency (rf) spectroscopy. A signature of strong correlations is observed above the critical temperature but also at spin polarizations where superfluidity is quenched …

Fission dynamics in a microscopic theory
… with TDSLDA formalism is presented. The role of pairing correlations in fission dynamics is demonstrated quantitatively. It is also shown that independent TDSLDA trajectories with different initial conditions on the potential energy surface generate almost the same fission fragment (FF) …

First experimental evidence of the Giant Pairing Vibration in atomic nuclei
… work is the understanding of the effects of the pairing force between nucleons in the structure of the atomic nuclei and in the nuclear reactions. This research is focused on the study of two-neutron transfer reactions, which are among the most effective probes to excite the nuclear pairing …
