Abstract

In this paper, we study a new class of AdS/BCFT setups, where the world-volumes of end-of-the-world branes (EOW branes) are given by flat spaces, to explore flat space holography from an AdS bulk. We show that they provide gravity duals of CFTs in the presence of null boundaries. Our holographic calculations lead to many new predictions on entanglement entropy, correlation functions and partition functions for CFTs with null boundaries. By considering a bulk region between two EOW branes, we present an AdS/BCFT explanation that the flat space gravity is dual to a Carrollian CFT (CCFT), including the swing surface calculation of entanglement entropy.

通过AdS/BCFT实现平面空间全息

在本文中，我们研究了一类新的AdS/BCFT设置，其中世界末日膜（EOW膜）的世界体积由平面空间给出，以探索平面空间全息。我们证明了它们在零边界存在下提供了cft的重力对偶。我们的全息计算对具有零边界的cft的纠缠熵、相关函数和配分函数进行了许多新的预测。通过考虑两个EOW膜之间的大块区域，我们给出了平面空间引力与卡罗里CFT （CCFT）对偶的AdS/BCFT解释，包括纠缠熵的摆动面计算。
