论文摘要
我们在协方差密度功能理论框架内的强烈磁场下，在强烈的磁场下构建了一个新的状态方程。物质的组成包括超子以及$δ$ rensonances。核次功能向高核部门的扩展受到$λ$和$ξ$ -Hypernuclei的实验数据的约束。我们发现，与非磁性情况相比，状态方程与磁场的包含僵硬，这增加了中子星的最大质量。此外，此问题的陌生部分得到了增强。几种可观察的物品，例如狄拉克有效的质量，粒子丰度等显示出典型的振荡行为，这是磁场和/或密度的函数，该磁场的函数可追溯到兰道水平的职业模式。
We construct a new equation of state for the baryonic matter under an intense magnetic field within the framework of covariant density functional theory. The composition of matter includes hyperons as well as $ Δ$-resonances. The extension of the nucleonic functional to the hypernuclear sector is constrained by the experimental data on $Λ$ and $Ξ$-hypernuclei. We find that the equation of state stiffens with the inclusion of the magnetic field, which increases the maximum mass of neutron star compared to the non-magnetic case. In addition, the strangeness fraction in the matter is enhanced. Several observables, like the Dirac effective mass, particle abundances, etc show typical oscillatory behavior as a function of the magnetic field and/or density which is traced back to the occupation pattern of Landau levels.
