论文摘要
通过将AD/BCFT对应关系和Brane World全息相结合，我们期望边界综合场理论（BCFT）与重力系统之间的等效关系与CFT耦合。但是，目前尚不清楚BCFT的边界条件如何在重力系统中翻译。我们通过查看纠缠熵和能量通量保护的计算，在二维设置中检查了这种二元性关系。我们还确定了对BCFT边界动力学双重的二维引力。此外，我们表明，通过考虑打开标量字段的重力解决方案，我们可以在ADS/BCFT中正确重现一个点函数。
By combining the AdS/BCFT correspondence and the brane world holography, we expect an equivalence relation between a boundary conformal field theory (BCFT) and a gravitational system coupled to a CFT. However, it still remains unclear how the boundary condition of the BCFT is translated in the gravitational system. We examine this duality relation in a two-dimensional setup by looking at the computation of entanglement entropy and energy flux conservation. We also identify the two-dimensional gravity which is dual to the boundary dynamics of a BCFT. Moreover, we show that by considering a gravity solution with scalar fields turned on, we can reproduce one point functions correctly in the AdS/BCFT.
