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…

Timelike entanglement entropy Revisited

Xin Jiang, Haitang Yang

We present an operator-algebraic definition for timelike entanglement entropy in QFT under a few mild postulates. This rigorously defined timelike entanglement entropy is real-valu…

Entanglement Entropy of Mixed State in Thermal CFT

Xin Jiang, Haitang Yang, Zilin Zhao

Using the subtraction approach, we give the bipartite mixed state entanglement entropy in thermal . With these entanglement entropies, we examine in detail the hologr…

Mixed State Entanglement Entropy in CFT

Xin Jiang, Peng Wang, Houwen Wu +1

How to calculate the entanglement entropy between two subsystems for a mixed state has remained an important problem. In this paper, we provide a straightforward method, namely the…

Realization of "ER=EPR"

Xin Jiang, Peng Wang, Houwen Wu +1

We provide a concrete and computable realization of the conjecture, by deriving the Einstein-Rosen bridge from the quantum entanglement in the thermofield double CFT. The…

How Einstein's Equation Emerges From CFT

Xin Jiang, Peng Wang, Houwen Wu +1

The {\it finiteness} of the entanglement entropies between disjoint subsystems enables us to show that, the dynamical equation of the entanglement entropy in CFT is precisely t…

An alternative to purification in CFT

Xin Jiang, Peng Wang, Houwen Wu +1

In conformal field theories, in contrast to \emph{adding} some auxiliary states into the bipartite mixed state as the usual purifications do, we show a pure entangled stat…
