Superfluidity in neutron matter and nuclear matter with realistic interactions

Superfluidity in Neutron Star Matter

Proton and Neutron Superfluidity in Asymmetric Nuclear Matter

We investigate the 1S0 neutron and proton superfluidity in isospin asymmetric nuclear matter. We have concentrated on the isospin dependence of the pairing gaps and the effect of a microscopic three-body force. It is found that as the isospin asymmetry goes higher, the neutron 1S0 superfluid phase shrinks gradually to a smaller density domain, while the proton one extends rapidly to a much wide...

0 Dispersive effects in neutron matter superfluidity

The explicit energy dependence of the single particle self-energy (dispersive effects), due to short range correlations, is included in the treatment of neutron matter superfluidity. The method can be applied in general to strong interacting fermion systems, and it is expected to be valid whenever the pairing gap is substantially smaller than the Fermi kinetic energy. The results for neutron ma...

Neutron Interactions with Matter

How neutrons interact with matter aflkcts the ways in which assays can be pdormed with neutrqs. Neutron interactions with the assay material affkct the interpretation of neutron measurements and limit the amount of fissile material the assay instrument can contain safely. A neutron detector is based on some neutron interaction with the material in the detector. Also, neutron interactions with s...

Proton and Neutron Superfluidity in β-stable Neutron Star Matter

We investigate the effect of a microscopic three-body force on the proton and neutron superfluidity in the 1S0 channel in β-stable neutron star matter. It is found that the three-body force has only a small effect on the neutron 1S0 pairing gap, but it suppresses strongly the proton 1S0 superfluidity in β-stable neutron star matter.
