# Cauchy slice holography A large enough [[0170 TTbar|T-T-bar]] deformation of a Euclidean CFT moves the boundary to a Cauchy surface in the Lorentzian bulk. ## Refs - early foundational work: [[2008#Freidel]] - OG: [[2022#Araujo-Regado, Khan, Wall]] - de Sitter: [[2022#Araujo-Regado]] - equivalent between phase spaces: [[2025#Khan]] ## Generalisations - to other bulk theories: - [[1991#Halliwell, Hartle]] shows that [[0345 Wheeler-DeWitt (WdW) equation|WdW]] equations for general theories are satisfied when the state is defined by a path integral that respects diffeomorphism etc., suggesting that [[2022#Araujo-Regado, Khan, Wall]] works in more general theories
