论文摘要
在本文中，我们分析并讨论了2D Jackiw-teitelboim（JT）重力，并在渐近抗DE保姆（ADS）的空间中耦合到原代效率。我们在极端黑洞地平线外的无质量狄拉克场的特殊解决方案，并在JT重力中找到DILATON的解决方案。二维JT重力时空是共形的平坦，我们计算了Weyl转换下主要费米磁场的两个点相关因子。这项工作的关键是提出一种标准技术，该技术称为分解而不是CFT方法。我们以保形因子为fermion磁场重新定义了磁场，并使用分解技术来得出JT重力中无质量狄拉克场的重新归一化纠缠熵。
In this paper we analyse and discuss 2D Jackiw-Teitelboim (JT) gravity coupled to primary fermion fields in asymptotically anti-de Sitter (AdS) spacetimes. We get a particular solution of the massless Dirac field outside the extremal black hole horizon and find the solution for the dilaton in JT gravity. Two dimensional JT gravity spacetime is conformally flat, we calculate the two point correlators of primary fermion fields under the Weyl transformations. The key point of this work is to present a standard technique which is called resolvent rather than CFT methods. We redefine the fields in terms of the conformal factor as the fermion fields, and we use the resolvent technique to derive the renormalized entanglement entropy for massless Dirac fields in JT gravity.
