# Cosmological Aspects of String Compactifications

## Abstract

The organization of this work is as follows. In Chapters 2, 3, and 4 they discuss the dynamics of unfixed moduli in quantum field theory and in string theory, with emphasis on applications to cosmological model-building. Moduli-stabilizing effects are not included, because the goal is to understand the evolution of moduli whose potentials remain approximately flat. In Chapter 5 they develop a technique for stabilizing moduli in the heterotic string, and they construct the first stabilized, weakly-coupled heterotic vacua. In Chapter 6 they utilize advances in the stabilization of type IIB compactifications to build the first models of inflation in stabilized string vacua. Finally, in Chapter 7 they examine the effects of volume-stabilization on the inflaton mass in closely-related scenarios of string inflation.
