摘要:

通过构造以D(-1)-膜为D-瞬子的D3-膜的构型,研究了三维Yang-Mills Chern-Simons全息理论.由于D-瞬子的存在,具有不一致嵌入函数的D 7-膜能够被引入,以便在对偶理论中包括基本费米子(作为味道)和陈-西蒙斯项(在非常低的能量下)。在孤子背景下研究了零温下的真空结构,说明了瞬子存在时的拓扑相变。此外,由于禁闭/解除禁闭相变可以全息地识别为体中的Hawking-Page相变,因此我们通过收集体在壳作用作为热力学自由能来计算解除禁闭相变的临界温度.另一方面,由于束缚态也可以用纠缠熵来表征,我们利用RT公式计算了平板结构中的纠缠熵的差异。总之,我们发现临界温度的行为与由纠缠熵决定的临界长度的行为在定性上是一致的,这意味着纠缠熵确实可能是我们装置中禁闭的一个特征,D3-D(-1)系统将是研究三维规范理论的一个显著途径。

英文摘要:

By constructing the configuration of D3-branes with D(-1)-branes as D-instantons, we study the three-dimensional Yang-Mills Chern-Simons theory in holography. Due to the presence of the D-instantons, the D7-branes with discrepant embedding functions are able to be introduced in order to include the fundamental fermions (as flavors) and the Chern-Simons term (at very low energy) in the dual theory. The vacuum structure at zero temperature is studied in the soliton background and it illustrates the topological phase transition in the presence of instantons. Moreover, since the confinement/deconfinement phase transition could be holographically identified as the Hawking-Page transition in the bulk, we accordingly calculate the critical temperature of the deconfinement phase transition by collecting the bulk onshell action as the thermodynamical free energy. On the other hand, we evaluate the difference of the entanglement entropy in slab configuration by using the RT formula since the confinement may also be characterized by the entanglement entropy. Altogether we find the behavior of the critical temperature is in qualitative agreement with the behavior of the critical length determined by the entanglement entropy which implies the entanglement entropy could indeed be a character of the confinement in our setup and the D3-D(-1) system would be a remarkable approach to study the three-dimensional gauge theory.
