Journal ArticleDOI
Semiclassical relations and IR effects in de Sitter and slow-roll space-times
TL;DR: In this paper, the authors calculate IR divergent graviton one-loop corrections to scalar correlators in de Sitter space, and show that the leading IR contribution may be reproduced via simple semiclassical consistency relations.

Journal ArticleDOI
The fate of four dimensions
TL;DR: In this article, it is argued that the existence of a positive vacuum energy generically implies catastrophic instability of our four-dimensional world and that the most generic instability is a decompactification transition to growth of the extra dimensions, although other equally bad transitions may take place.

Effective theories and black hole production in warped compactifications
Steven B. Giddings,Emanuel Katz +1 more
TL;DR: In this paper, the authors investigated aspects of the four-dimensional (4D) effective description of brane world scenarios based on warped compactification on anti-de Sitter space and gave the linearized description of the 4D stress tensor corresponding to an arbitrary 5D matter distribution.
