论文摘要
我们使用扰动方法构建了全息janus解决方案，该解决方案在四维测量中描述了M2-branes理论中的共形界面。特别是，我们研究了由Bobev，Pilch和Warner（2014）得出的三个爱因斯坦 - 标准系统及其BPS方程。我们感兴趣的动作都是$ d = 11 $的一致截断，被选择为$（4）\ times so（4）$（4）$，$ su（3）\ times u（1）\ times u（times u（times u（1）\ times u（1）$）和$ g_2 $ symmetry symmetry子组$（8）$（8）$。通过计算最小面积表面和相关的全息纠缠熵来说明我们的半分析结果的效用。
We construct holographic Janus solutions, which describe a conformal interface in the theory of M2-branes, in four-dimensional gauged supergravities using a perturbative method. In particular, we study three Einstein-scalar systems and their BPS equations, which are derived by Bobev, Pilch, and Warner (2014). The actions of our interest are all consistent truncations of $D=11$ supergravity chosen to be invariant under $SO(4)\times SO(4)$, $SU(3)\times U(1)\times U(1)$, and $G_2$ symmetry subgroups of $SO(8)$ respectively. The utility of our semi-analytic result is illustrated by the calculation of minimal area surface and the associated holographic entanglement entropy.
