论文摘要
我们继续研究了一个新近构建的全息QCD模型，该模型补充了磁场。我们考虑了夸克，反夸克对的全息二，并根据Quark距离，温度和磁场来调查其熵之外的熵。我们在反封码附近的强烈减小熵和熵变化中获得了明显的磁场依赖性。我们发现了各种支持反磁催化的证据。发现出现的熵力在磁场上变得更强壮，从而促进夸克解离。我们还探测了Quarkonium状态的动态解离，发现与磁场的分离更快。至少静态预测应该与未来的晶格数据进行定性比较。
We continue the study of a recently constructed holographic QCD model supplemented with magnetic field. We consider the holographic dual of a quark, anti-quark pair and investigate its entropy beyond the deconfinement phase transition in terms of interquark distance, temperature and magnetic field. We obtain a clear magnetic field dependence in the strongly decreasing entropy near deconfinement and in the entropy variation for growing interquark separation. We uncover various supporting evidences for inverse magnetic catalysis. The emergent entropic force is found to become stronger with magnetic field, promoting the quarkonium dissociation. We also probe the dynamical dissociation of the quarkonium state, finding a faster dissociation with magnetic field. At least the static predictions should become amenable to a qualitative comparison with future lattice data.
