鼓泡几何矩阵模型中的靶空间纠缠

Target space entanglement in a matrix model for the bubbling geometry

Asato Tsuchiya, Kazushi Yamashiro

摘要:

在描述$\mathcal{N}=4$超杨-米尔斯理论中手征主扇区的复矩阵模型中研究了目标空间纠缠熵.矩阵模型的目标空间是复矩阵特征值分布的二维平面。本征值被视为费米子的位置坐标,本征值分布对应于费米子形成的液滴。液滴用指定起泡几何形状中的边界条件的液滴来标识。我们考虑了矩阵模型中对应于$AdS_5\times S^5$、AdS巨引力子和气泡几何中巨引力子的态。我们计算了矩阵模型中每个态的子区域的目标空间纠缠熵以及冒泡几何中子区域边界的面积,并发现它们之间的定性一致性。

英文摘要:

We study the target space entanglement entropy in a complex matrix model that describes the chiral primary sector in $\mathcal{N}=4$ super Yang-Mills theory, which is associated with the bubbling AdS geometry. The target space for the matrix model is a two-dimensional plane where the eigenvalues of the complex matrix distribute. The eigenvalues are viewed as the position coordinates of fermions, and the eigenvalue distribution corresponds to a droplet formed by the fermions. The droplet is identified with one that specifies a boundary condition in the bubbling geometry. We consider states in the matrix model that correspond to $AdS_5\times S^5$, an AdS giant graviton and a giant graviton in the bubbling geometry. We calculate the target space entanglement entropy of a subregion for each of the states in the matrix model as well as the area of the boundary of the subregion in the bubbling geometry, and find a qualitative agreement between them.
