Spin polarized asymmetric nuclear matter and neutron star matter within the lowest order constrained variational method

Abstract

In this paper, we calculate properties of the spin polarized asymmetrical nuclear matter and neutron star matter, using the lowest order constrained variational (LOCV) method with the AV 18 , Reid93, U V 14 and AV 14 potentials. According to our results, the spontaneous phase transition to a ferromagnetic state in the asymmetrical nuclear matter as well as neutron star matter do not occur.

Nuclear response for the Skyrme effective interaction with zero-range tensor terms. II. Sum rules and instabilities

“…In the same spirit, a detailed study of sum rules can enlighten the contribution of the tensor for various physical situations (see for instance [20]). Finally, applications to pure neutron matter is of great importance (see for instance [45][46][47][48][49][50][51][52][53][54][55][56][57]) and will be the subject of a forthcoming article in preparation. In that case, the above formulae are no longer directly usable and have been adapted to that specific case.…”

Maximum mass of a hot neutron star with a quark core

“…In our calculations, the equation of state of hot nucleonic matter is determined using the lowest order constrained variational (LOCV) method as follows [9][10][11][12][13][14][15][16]. We adopt a trail wave function as…”

Ferromagnetic and antiferromagnetic spin-ordering stabilities of asymmetric nuclear matter: Lowest-order constrained variational method

“…In these works microscopic calculations employing the LOCV method with realistic nucleon-nucleon potentials were used. We also calculated the energy per particle and other properties of polarized asymmetric nuclear matter [49] and polarized neutron star matter [49] by using the LOCV method and parabolic approximation. We concluded that a spontaneous phase transition to the ferromagnetic state in these types of matter does not occur.…”
