Black holes in Gödel-type universes with a cosmological constant
نویسندگان
چکیده
We discuss supersymmetric black holes embedded in a Gödel-type universe with cosmological constant in five dimensions. The spacetime is a fibration over a four-dimensional Kähler base manifold, and generically has closed timelike curves. Asymptotically the space approaches a deformation of AdS5, which suggests that the appearance of closed timelike curves should have an interpretation in some deformation of D = 4, N = 4 super-YangMills theory. Finally, a Gödel-de Sitter universe is also presented and its causal structure is discussed. [email protected] [email protected]

On the Thermodynamics of Gödel Black Holes
After a brief review of Gödel-type universes in string theory, we discuss some intriguing properties of black holes immersed in such backgrounds. Among these are the upper bound on the entropy that points towards a finite-dimensional Hilbert space of a holographically dual theory, and the minimum black hole temperature that is reminiscent of the Hawking-Page transition. Furthermore, we discuss ...

This article reviews recent developments in the study of universes with a positive cosmological constant in string theory. 1. The Challenge of Time It is evident that the world around us changes in time. At cosmological scales there is strong evidence that the universe was much hotter and denser some 13 billion years ago and has expanded and cooled since then, probably even undergoing an early ...

Vacuum Einstein theory in three spacetime dimensions is locally trivial, but admits many solutions that are globally different, particularly if there is a negative cosmological constant. The classical theory of such locally “anti-de Sitter” spaces is treated in an elementary way, using visualizable models. Among the objects discussed are black holes, spaces with multiple black holes, their hori...
