On the stability of string vacua
Speaker:Magdalena Larfors (LMU Munich)
Abstract:Compactifications of string theory constitute a promising framework for reproducing interesting cosmological features, such as inflation. An important subtlety in these constructions is the stabilization of moduli; four-dimensional scalar fields that describe fluctuations of the geometry of the compactified dimensions. In this talk, I will review how moduli can be fixed in compactifications of type II string theory. I will also discuss cosmological features of the resulting four-dimensional vacua, and how metastable vacua can decay through the formation of new vacuum bubbles.
