论文摘要
我们在具有共形边界的二维CFT中提出了当地操作员的重力双重淬火。这是由三维广告空间中的大量激发给世界brane（eow brane）中给出的。由于引力反应，EOW Brane以非平凡的方式变形。我们表明，从重力双重二元组和BCFT计算出的能量量张量和纠缠熵完美地匹配。有趣的是，这种比较避免了以优雅的方式折叠Eow brane。
We present a gravity dual of local operator quench in a two-dimensional CFT with conformal boundaries. This is given by a massive excitation in a three-dimensional AdS space with the end of the world brane (EOW brane). Due to the gravitational backreaction, the EOW brane gets deformed in a nontrivial way. We show that the energy-momentum tensor and entanglement entropy computed from the gravity dual and from the BCFT in the large $c$ limit match perfectly. Interestingly, this comparison avoids the folding of the EOW brane in an elegant way.
