Spin polarized neutron matter and magnetic susceptibility within the Brueckner–Hartree–Fock approximation
The Brueckner–Hartree–Fock formalism is applied to study spin polarized neutron matter properties. Results of the total energy per particle as a function of the spin polarization and density are presented for two modern realistic nucleon-nucleon interactions, Nijmegen II and Reid93. We find that the dependence of the energy on the spin polarization is practically parabolic in the full range of ...
متن کامل1 Spin susceptibility of neutron matter at zero temperature
The Auxiliary Field Diffusion Monte Carlo method is applied to compute the spin susceptibility and the compressibility of neutron matter at zero temperature. Results are given for realistic interactions which include both a two–body potential of the Argonne type and the Urbana IX three–body potential. Simulations have been carried out for about 60 neutrons. We find an overall reduction of the s...

متن کاملFerromagnetism of dense matter and magnetic properties of neutron stars
Possible consequences of ferromagnetic transition in dense matter suggested recently by Kutschera and Wójcik, for the magnetic properties of neutron stars, are studied. Specific model of dense matter, in which a small admixture of protons is completely polarized due to their interaction with neutrons, is considered. Magnetic field of neutron stars with a ferromagnetic core are calculated within...
متن کاملPauli Paramagnetism of Neutron Star Matter and the Upper Limit for Neutron Star Magnetic Fields
A relativistic version of Pauli paramagnetism for n − p − e system inside a strongly magnetized neutron star has been developed. An analytical expressions for the saturation value of magnetic field strength for each of these constituents at which they are completely polarized have been obtained. From the fully polarized configuration of electronic component, an upper limit for neutron star magn...
