AdS Space from Entanglement Entropy

Seungjoon Hyun, Sang A. Park

Research output: Contribution to journalArticle


We show that the anti-de Sitter(AdS) space naturally emerges from the conformal field theory (CFT). The behavior of the leading divergent term in the entanglement entropy implies the underlying AdS geometry. The coefficient of the leading divergent term is related to the radius of the AdS space. All these are confirmed fully for two-dimensional CFTs. We also give comments for higher dimensional CFTs.
