论文摘要
我们优化了早期引入的5维重力解决方案，能够在强磁背景下全息捕获（晶格）QCD的几个定性方面，例如弦伸张力的各向异性行为，逆催化，在去解式转变或范围侵入术的敏感性的水平上。在这里，我们不断地修改了所考虑的爱因斯坦 - 马克斯韦 - 迪拉顿系统的解决方案，不仅克服了早期工作的Quark-Antiquark潜力势足，在Quark-Antiquark电位上的大距离上进行了较大的扁平化，而且还封装了在探针近似中的手性过渡的反向催化。这使我们的动力全息QCD模型再次更接近一个阶段，在该阶段可以用来预测磁性QCD数量，而不是通过晶状体技术直接计算。
We refine an earlier introduced 5-dimensional gravity solution capable of holographically capturing several qualitative aspects of (lattice) QCD in a strong magnetic background such as the anisotropic behaviour of the string tension, inverse catalysis at the level of the deconfinement transition or sensitivity of the entanglement entropy to the latter. Here, we consistently modify our solution of the considered Einstein-Maxwell-dilaton system to not only overcome an unphysical flattening at large distances in the quark-antiquark potential plaguing earlier work, but also to encapsulate inverse catalysis for the chiral transition in the probe approximation. This brings our dynamical holographic QCD model yet again closer to a stage at which it can be used to predict magnetic QCD quantities not directly computable via lattice techniques.
