String constructions and cosmological spacetimes
Abstract/Contents
- Abstract
- We study connections between the macroscopic features of cosmological spacetimes and the underlying microscopic description. String theory provides a useful toolkit for addressing high energy problems and conceptual issues in gravitational theories, but the questions we hope to address are not necessarily confined to this framework. Models of cosmology derived from string theory generically include additional fields that may affect cosmic inflation and its observables, and they provide a top-down perspective for organizing the predictions of inflationary models. We also use brane constructions to gain a microscopic perspective on dual 'holographic' descriptions for de Sitter and Friedmann-Robertson-Walker spacetimes, and we express the horizon entropy in terms of microscopic parameters. Such constructions also motivate more general studies of time-dependence in field theories and its effect on renormalization group flow. Finally, we construct an oscillating universe at the level of general relativity using sources satisfying the null energy condition and analyze its stability to linear order, and we discuss the implications for singularity theorems.
