论文摘要
在这项工作中，我们研究了自发性手性对称性破坏的有限密度效应以及在背景磁场的影响下以$ 2+1 $尺寸的影响。为此，我们使用基于插值DILATON轮廓的改进的全息软壁模型。我们发现有限密度下的磁性催化。我们观察到，手性冷凝物随着密度的增加而降低，而两种影响（添加磁场和化学电位）总和增加了手性冷凝物。
In this work we study finite density effects in spontaneous chiral symmetry breaking as well as chiral phase transition under the influence of a background magnetic field in $ 2+1 $ dimensions. For this purpose, we use an improved holographic softwall model based on an interpolated dilaton profile. We find inverse magnetic catalysis at finite density. We observe that the chiral condensate decreases as the density increases, and the two effects (addition of magnetic field and chemical potential) sum up decreasing even more the chiral condensate.
