论文摘要
我们研究了在ADS/BCFT内存在边界的情况下，在零密度下以零密度的两种不同全息隐形系统的电导率和纠缠结构。第一个间隙系统由爱因斯坦 - 标准重力描述，第二个是soliton几何形状的双重。我们表明，在这两个系统中，沿BCFT边界的空间方向的块和边界电导率都是微不足道的。对于第一个系统，当我们增加子系统的大小时，重新归一化的纠缠熵始终是非负的，并且根据不连续的，连续或平稳的行为而单调降低，具体取决于布兰的有效张力。而对于具有边界的广告索尼顿，重新归一化的纠缠熵仅在我们增加子系统的大小时表现出不连续的下降。
We study the conductivities and entanglement structures of two different holographic gapped systems at zero density in the presence of boundaries within AdS/BCFT. The first gapped system is described by the Einstein-scalar gravity and the second one is the dual of AdS soliton geometry. We show that in both these two systems the bulk and boundary conductivities along the spatial direction of the boundary of BCFT are trivial. For the first system, when we increase the size of the subsystem the renormalized entanglement entropy is always non-negative and monotonically decreasing with discontinuous, or continuous, or smooth behavior, depending on the effective tension of the brane. While for the AdS soliton with a boundary, the renormalized entanglement entropy only exhibits a discontinuous drop when we increase the size of the subsystem.
