关于在AdS/CFT correspondence中嵌入暴胀的一些评论

Some comments on embedding inflation in the AdS/CFT correspondence

David A. Lowe

摘要:

反德西特空间/共形场论对应(AdS/CFT)可能提供一个完整的弦论公式,它是关于自然产生永恒暴胀的稳定和亚稳真空的。作为一个模型,这个过程中,我们认为气泡的解决方案与德西特内部,通过修补在一起的DS和Schwarzschild-AdS解决方案沿气泡壁。对于这些解的一个有趣子类,在黑洞内部,泡壁达到类空无穷大。包括扰动的影响导致从该点发出的零奇点。这样的解决方案被解释为在一个单一的CFT的状态,并示出与全息熵界限兼容。该构造建议将de Sitter熵解释为有效场论中的自由度总数,并具有新颖的自适应步长截止。

英文摘要:

The anti-de Sitter space/conformal field theory correspondence (AdS/CFT) can potentially provide a complete formulation of string theory on a landscape of stable and metastable vacua that naturally give rise to eternal inflation. As a model for this process, we consider bubble solutions with de Sitter interiors, obtained by patching together dS and Schwarzschild-AdS solutions along a bubble wall. For an interesting subclass of these solutions the bubble wall reaches spacelike infinity in the black hole interior. Including the effects of perturbations leads to a null singularity emanating from this point. Such solutions are interpreted as states in a single CFT, and are shown to be compatible with holographic entropy bounds. The construction suggests de Sitter entropy be interpreted as the total number of degrees of freedom in effective field theory, with a novel adaptive stepsize cutoff.
