全息共形场论中的非几何态

Non-geometric States in a Holographic Conformal Field Theory

Wu-zhong Guo, Feng-Li Lin, Jiaju Zhang

摘要:

在AdS $_3$ /CFT $_2$对应中,我们发现了一些共形场论(CFT)态,它们没有Bañados几何的体描述.我们详细阐述了CFT状态的几何约束,即,通过比较全息方法和CFT中的复制技巧分别得到的纠缠/Rényi熵的中心荷的阶数,证明了CFT具有对偶Bañados度规.我们发现几何CFT态满足玻尔的对应原理,通过减少量子KdV系列的经典对应。我们称满足几何约束的CFT状态为几何状态,否则称为非几何状态。我们给出了几何态和非几何态的例子,后者包括叠加态和后代态。

英文摘要:

In the AdS$_3$/CFT$_2$ correspondence, we find some conformal field theory (CFT) states that have no bulk description by the Bañados geometry. We elaborate the constraints for a CFT state to be geometric, i.e., having a dual Bañados metric, by comparing the order of central charge of the entanglement/Rényi entropy obtained respectively from the holographic method and the replica trick in CFT. We find that the geometric CFT states fulfill Bohr's correspondence principle by reducing the quantum KdV hierarchy to its classical counterpart. We call the CFT states that satisfy the geometric constraints geometric states, and otherwise non-geometric states. We give examples of both the geometric and non-geometric states, with the latter case including the superposition states and descendant states.
