Pairing Correlations
Part 1: description of odd nuclei in mean-field theories. Abstract In order to extract informations on pairing correlations in nu-clei from experimental mass differences, the different contributions to odd-even mass differences are investigated within the Skyrme HFB 1 method. In this first paper, the description of odd nuclei within HFB is discussed since it is the key point for the understandi...
متن کاملPrecursor Pairing Correlations and Pseudogaps
I begin by briefly reviewing various experimental results on the pseudogap phenomena in underdoped cuprates. I argue that, taken together, all of these lead to a picture of singlet pairing above Tc. I then explore the idea that the pseudogap is a normal state precursor of the superconducting gap due to local, dynamic pairing correlations in a state without long range phase coherence. Early work...
متن کاملCorrelations and Pairing in Nuclear
The innuence of correlations on the critical temperature and density for the onset of superruidity in nuclear matter is investigated within the scheme of Nozi eres and Schmitt-Rink 1]. For symmetric nuclear matter a smooth transition from Bose-Einstein condensation (BEC) of deuteron-like bound states at low densities and low temperatures to Bardeen-Cooper-Schrieeer (BCS) pair-ing at higher dens...
متن کاملPairing Correlations in Halo Nuclei
Paring correlations in weakly bound halo nuclei He and Li are studied by using a threebody model with a density-dependent contact interaction. We investigate the spatial structure of two-neutron wave function in a Borromean nucleus Li. The behavior of the neutron pair at different densities is simulated by calculating the two-neutron wave function at several distances between the core nucleus L...
متن کاملPairing correlations and transitions in nuclear systems
We discuss several pairing-related phenomena in nuclear systems, ranging from superfluidity in neutron stars to the gradual breaking of pairs in finite nuclei. We describe recent experimental evidence that points to a relation between pairing and phase transitions (or transformations) in finite nuclear systems. A simple pairing interaction model is used in order to study and classify an eventua...
