QHD equation of state for strongly magnetized neutron stars
QHD equation strongly magnetized neutron stars
2011/7/21
We investigate the quantum hadrodynamic equation of state for neutron stars (with and without including hyperons) in the presence of strong magnetic fields.
Oscillations of hot, young neutron stars: Gravitational wave frequencies and damping times
Oscillations of hot young neutron stars
2011/7/21
We study how the frequencies and damping times of oscillations of a newly born, hot proto-neutron star depend on the physical quantities which characterize the star quasi-stationary evolution which fo...
A model for space and time-like proton (neutron) form factors
space time-like proton (neutron)
2011/7/21
Recent experiments on the electromagnetic proton and neutron form factors reveal very peculiar features such as the decreasing of the ratio of electric to magnetic form factor of the proton as functio...

Neutron rich matter is central to many fundamental questions in nuclear physics and astrophysics. Moreover, this material is being studied with an extraordinary variety of new tools such as the Facili...
The cluster structure of the inner crust of neutron stars in the Hartree-Fock-Bogoliubov approach
cluster structure inner crust neutron stars approach
2011/10/17
We analyse how the structure of the inner curst is influenced by the pairing correlations. The inner-crust matter, formed by nuclear clusters immersed in a superfluid neutron gas and ultra-relativisti...
New eigen-mode of spin oscillations in the triplet superfluid condensate in neutron stars
Neutron star Superfl uidity Spin waves
2011/10/14
The eigen mode of spin oscillations with $\omega\simeq \sqrt{58/35}\Delta$ is predicted to exist besides already known spin waves with $\omega \simeq\Delta /\sqrt{5}$ in the triplet superfluid neutron...
Study of the neutron skin thickness of ${}^{208}$Pb in mean field models
mean field models
2011/7/20
We study whether the neutron skin thickness $\Delta r_{np}$ of ${}^{208}$Pb originates from the bulk or from the surface of the neutron and proton density distributions in mean field models.

neutron-proton system Relativistic separable interaction
2011/7/20
Within a covariant Bethe-Salpeter approach, the relativistic complex separable neutron-proton interaction kernel is proposed. The uncoupled partial-wave states with the total angular momentum $J$=0,1 ...
Emergence of pygmy dipole resonances: Magic numbers and neutron skins

2011/7/20
The pygmy dipole resonances (PDR) for even-even nuclei in 8=erforming a systematic calculation of the random-phase approximation with the Skyrme functional of SkM*. The calculation...
Testing the density matrix expansion against ab initio calculations of trapped neutron drops
density matrix neutron drops
2011/7/20
Microscopic input to a universal nuclear energy density functional can be provided through the density matrix expansion (DME), which has recently been revived and improved.

neutron-neutron scattering length
2011/7/20
We compute a model-independent correlation between the difference of neutron-neutron and proton-proton scattering lengths |a(nn)-a^C(pp)| and the splitting in binding energies between Helium-3 and tri...

2011/7/20
Neutron star crustal matter, whose properties are relevant in many models aimed at explaining observed astrophysical phenomena, has so far always been studied using a mean field approach. In order to ...
