The single-particle spectral functions in asymmetric nuclear matter are computed using the ladder approximation within the theory of finite temperature Green’s functions. The internal energy and the… (More)

P. Czerski Institute Fiz. Jadrowej, Pl-31-342 Krakow, Poland The structure of nucleon self-energy in nuclear matter is evaluated for various realistic models of the nucleon-nucleon (NN) interaction.… (More)

The pairing properties of nuclear systems are a sensitive probe of the effective nucleon-nucleon interactions. We compare the 1 S 0 pairing gaps in nuclear and neutron matter derived from the… (More)

Correlations in the nuclear wave-function beyond the mean-field or Hartree-Fock approximation are very important to describe basic properties of nuclear structure. Various approaches to account for… (More)

We explore the phase diagram of a two-component ultracold atomic Fermi gas interacting with zero-range forces in the limit of weak coupling. We focus on the dependence of the pairing gap and the free… (More)

We study the symmetry energy in infinite nuclear matter employing a nonrelativistic Brueckner-Hartree-Fock approach and using various new nucleonnucleon (NN) potentials, which fit np and pp… (More)

Different modern phase shift equivalent NN potentials are tested by evaluating the partial wave decomposition of the kinetic and potential energy of the deuteron. Significant differences are found,… (More)

Various modern nucleon-nucleon ( NN) potentials yield a very accurate fit to the nucleon-nucleon scattering phase shifts. The differences between these interactions in describing properties of… (More)

Isoscalar Cooper pairing in isospin asymmetric nuclear matter occurs between states populating two distinct Fermi-surfaces, each for neutrons and protons. The transition from a BCS-like to the normal… (More)

The pairing properties of nuclear systems are a sensitive probe of the effective nucleon-nucleon interactions. We compare the 1 S 0 pairing gaps in nuclear and neutron matter derived from the… (More)
