Quotient-AdS/BCFT:CFT $_2$对AdS $_3$商的全息边界

Quotient-AdS/BCFT: Holographic Boundary CFT$_2$ on AdS$_3$ Quotients

Sanjit Shashi

摘要:

全息原理作为量子引力的一般特征,应该允许考虑AdS/CFT以外的对偶。AdS/BCFT对应,其中的对偶场论具有局部共形对称性,并定义在一个流形上的边界,是这样一个例子。受AdS $_3$的时空等距性的启发,为了构造与多体CFT $_2$态对偶的多边界虫洞,我们发现这种对应可以通过将AdS/CFT与一些适当的商程序相结合来理解。此外,在三个散装尺寸,我们发现的例子商空间的AdS $_3$,以构建“自然”的具体BCFT $_2$真空状态,其中之一似乎描述了一种新的,随时间变化的BCFT $_2$的解决方案的散装。我们称这种使用了平行子的AdS/BCFT的特殊改进为平行子-AdS/BCFT对应。

英文摘要:

The holographic principle, being a generic feature of quantum gravity, should allow for the consideration of dualities other than AdS/CFT. The AdS/BCFT correspondence, in which the dual field theory has local conformal symmetry and is defined on a manifold with boundary, is one such example. Inspired by the quotienting of AdS$_3$ by spacetime isometries in order to construct multiboundary wormholes dual to multipartite CFT$_2$ states, we find that this correspondence can be understood by combining AdS/CFT with some appropriate quotient procedure. Furthermore, in three bulk dimensions, we find example quotient spaces of AdS$_3$ in order to construct "natural" bulk duals for specific BCFT$_2$ vacuum states, one of which appears to describe a novel, time-dependent BCFT$_2$ solution. We call this particular refinement of AdS/BCFT, in which we use quotients, the quotient-AdS/BCFT correspondence.
