S-branes and (Anti-)Bubbles in (A)dS Space

TL;DR

This paper constructs new asymptotically (A)dS geometries via analytic continuation of black hole solutions, revealing classes like S-branes, bubbles, and anti-bubbles, some of which are nonsingular and have complex horizon structures.

Contribution

It introduces a method to generate new (A)dS solutions through analytic continuation, expanding the landscape of known geometries relevant for holographic dualities.

Findings

Identified three classes of solutions: S-branes, bubbles, and anti-bubbles.

Discovered some solutions are nonsingular.

Generalized solutions include spinning and twisted geometries with complex horizons.

Abstract

We describe the construction of new locally asymptotically (A)dS geometries with relevance for the AdS/CFT and dS/CFT correspondences. Our approach is to obtain new solutions by analytically continuing black hole solutions. A basic consideration of the method of continuation indicates that these solutions come in three classes: S-branes, bubbles and anti-bubbles. A generalization to spinning or twisted solutions can yield spacetimes with complicated horizon structures. Interestingly enough, several of these spacetimes are nonsingular.
