The Stability

Using conventional MIT bag model of confinement, the stability of bulk strange quark matter (SQM) in the presence of a strong magnetic field at zero temperature and zero pressure has been investigated. The binding energy of SQM increases in the presence of strong magnetic field greater than or of the order of some critical value at which the cyclotron lines begin to occur. At finite temperature the pressure dependence of the system has also been presented, which differs significantly from zero magnetic field case.

The Stability

A relativistic version of the Landau theory of Fermi liquid in the presence of an ultrastrong magnetic field is developed. The direct and exchange interactions via the exchanges of both the scalar and the vector bosons are considered. The model is applied to a system of weakly interacting strange quark matter to study the stability of the system.

The Magnetic Field

We review the stability of magnetized strange quark matter (MSQM) within the phenomenological MIT bag model, taking into account the variation of the relevant input parameters, namely, the strange quark mass, baryon density, magnetic field and bag parameter. A comparison with magnetized asymmetric quark matter in β-equilibrium as well as with strange quark matter (SQM) is presented. We obtain that the energy per baryon for MSQM decreases as the magnetic field increases, and its minimum value at vanishing pressure is lower than the value found for SQM, which implies that MSQM is more stable than non-magnetized SQM. The mass–radius relation for magnetized strange quark stars is also obtained in this framework.

The Magnetic Field

The main properties of magnetized strangelets, namely, their energy per baryon, radius and electric charge, are studied in the unpaired strange quark matter phase. Temperature effects are taken into account in order to study their stability compared to the 56Fe isotope and non-magnetized strangelets within the framework of the MIT bag model. It is concluded that the presence of a magnetic field tends to stabilize more the strangelets, even when temperature is considered. We find that the electric charge is modified in the presence of the magnetic field, leading to higher charge values for magnetized strangelets, when compared to the non-magnetized case.

Universe Models

In this study, we have investigated generalized anisotropic universe models for magnetized strange quark matter (MSQM) distribution in the framework of [Formula: see text] gravitation theory. For this aim, we have used linearly varying deceleration parameter suggested by Akarsu and Dereli (2012) and equation of state for strange quark matter. For LRS Bianchi I universe model, the magnetic field was obtained as zero. But it was found to be different from zero for other universe models. Also, the geometric and physical aspects of the model are discussed in the conclusion.
