Finite Modular Hamiltonians and Their Singular Limits
Panyinyan Li, Jun Tao, Haitang Yang
Using the open solid torus as a finite parent, we revisit modular flow for spherical regions in conformal field theory. Its nonsingular angular evolution gives finite modular gener…
Exact and Finite de Sitter QFT from CFT
Haitang Yang
Parallel to the AdS Scale-Space construction in \cite{Yang:2026AdS}, we construct a -dimensional de Sitter QFT directly from -dimensional CFT data. The dS geometry is the…
Exact Holographic Kinematics in AdS/CFT
Haitang Yang
We propose that holography contains an exact kinematic sector distinct from holographic dynamics. The appropriate setting for this sector is a CFT on an open solid torus in the Wey…
Exact Bulk-Boundary Pairs in AdS/CFT
Xin Jiang, Peng Wang, Haitang Yang
We show that for a CFT on a flat open solid torus, the two point function in the Weyl frame is exactly paired with a finite geodesic lying entirely in the AdS bulk inte…
Derive Einstein equation from CFT entanglement entropy
Xin Jiang, Haitang Yang
We explicitly show how to derive the -dimensional Einstein equation from the entanglement entropy between codimension-one {\it disjoint} regions in -dimensional conformal…
Entanglement Entropy of Conformal Field Theory in All Dimensions
Xin Jiang, Haitang Yang
We provide a field-theoretic method to calculate entanglement entropy of CFT in all dimensions. This method works for entangling surfaces of arbitrary shape. The formalism manifest…
