论文摘要
我们研究了与手性相变相关的三位临界点的临界现象，在存在有限的重子数密度和外部磁场的情况下，它在D3/D7模型中出现。我们在数值上确定与热力学数量和相关函数相关的关键指数。我们发现，关键指数的值与平均场值一致。临界指数之间的缩放关系得到了满足，这意味着自由能和相关函数的缩放假设成立。我们的结果表明，传统的Landau理论很好地描述了D3/D7模型中三智度点的批判现象。
We study critical phenomena at a tricritical point associated with a chiral phase transition which emerges in the D3/D7 model in the presence of a finite baryon number density and an external magnetic field. We numerically determine critical exponents related to the thermodynamic quantities and correlation functions. We find that the values of the critical exponents agree with the mean-field values. The scaling relations between the critical exponents are satisfied, implying that the scaling hypothesis for the free energy and the correlation functions hold. Our results indicate that the critical phenomena at the tricritical point in the D3/D7 model are well described by the conventional Landau theory.
