标题： Magnetized Domain Walls in the Deconfined Sakai-Sugimoto Model at Finite Baryon Density

摘要： 磁化纯介子梯度（$\mathcal{5}\phi$）相在禁闭的萨卡伊- sugimoto 模型中在零温度和有限温度下被研究。我们发现温度对该相的影响非常小。该相的热力学性质表明，激发行为类似于标量孤立子自由粒子。通过将介子梯度相的自由能与竞争的多夸克-介子梯度（MQ-$\mathcal{5}\phi$）相进行比较，很明显纯介子梯度相不如 MQ-$\mathcal{5}\phi$相在热力学上更受青睐。然而，在重子化学势小于多夸克起始值的参数空间中，占主导地位的磁化核物质是介子梯度相。 显示英文摘要

摘要： The magnetized pure pion gradient ($\mathcal{5}\phi$) phase in the deconfined Sakai-Sugimoto model is explored at zero and finite temperature. We found that the temperature has very small effects on the phase. The thermodynamical properties of the phase shows that the excitations behave like a scalar solitonic free particles. By comparing the free energy of the pion gradient phase to the competing multiquark-pion gradient (MQ-$\mathcal{5}\phi$) phase, it becomes apparent that the pure pion gradient is less thermodynamically preferred than the MQ-$\mathcal{5}\phi$ phase. However, in the parameter space where the baryonic chemical potential is smaller than the onset value of the multiquark, the dominating magnetized nuclear matter is the pion gradient phase.
