We present how the surface-state correspondence, conjectured by Miyaji and Takayanagi, works in the setup of AdS(3)/CFT(2) by generalizing the formulation of a continuous multiscale entanglement renormalization group ansatz. The boundary states in conformal field theories play a crucial role in our formulation and the bulk diffeomorphism is naturally taken into account. We give an identification of bulk local operators which reproduces correct scalar field solutions on AdS(3) and bulk scalar propagators. We also calculate the information metric for a locally excited state and show that it reproduces the time slice of AdS(3).
我们通过推广连续多尺度纠缠重整化群假设的公式,展示了宫地和高柳所推测的表面态对应关系在AdS(3)/CFT(2)设置中的作用。共形场论中的边界态在我们的公式中起着关键作用,并且自然地考虑了体微分同胚。我们给出了体局部算符的一种识别,它能在AdS(3)上重现正确的标量场解和体标量传播子。我们还计算了局部激发态的信息度量,并表明它能重现AdS(3)的时间切片。
