Ryu-Takayanagi Formula for Multi-Boundary Black Holes from 2D Large-$c$ CFT Ensemble

Ning Bao, Hao Geng, Yikun Jiang

We study a class of quantum states involving multiple entangled CFTs in AdS${}_3$/CFT${}_2$, associated with multi-boundary black hole geometries, and demonstrate that the Ryu-Takayana…
