adS/dS超引力中的畴壁/宇宙学对应

Domain-wall/Cosmology correspondence in adS/dS supergravity

Kostas Skenderis, Paul K. Townsend, Antoine Van Proeyen

摘要:

在四维超引力的背景下,我们实现了(伪)超对称畴壁(宇宙学)的畴壁/宇宙学对应。OSP(2)|4)-不变的反德西特(adS)真空对应于一个特定的N=2 Maxwell-Einstein超引力理论的OSp(2^*| 2,2)-不变的de Sitter(dS)真空的一个特定的伪超引力模型,与“扭曲”的现实条件的旋量。更一般地说,前一种模型的超对称域壁对应于后一种模型的伪超对称宇宙学,我们明确给出了依赖于时间的伪Killing旋量。

英文摘要:

We realize the domain-wall/cosmology correspondence for (pseudo)supersymmetric domain walls (cosmologies) in the context of four-dimensional supergravity. The OSp(2|4)-invariant anti-de Sitter (adS) vacuum of a particular N=2 Maxwell-Einstein supergravity theory is shown to correspond to the OSp(2^*|2,2)-invariant de Sitter (dS) vacuum of a particular pseudo-supergravity model, with `twisted' reality conditions on spinors. More generally, supersymmetric domain walls of the former model correspond to pseudo-supersymmetric cosmologies of the latter model, with time-dependent pseudo-Killing spinors that we give explicitly.
