**Inflation and String Theory**

by **Daniel Baumann, Liam McAllister** - **arXiv** , **2014**

We review cosmological inflation and its realization in quantum field theory and string theory. We describe two intertwined approaches to the physics of inflation: from the bottom up in effective field theory, and from the top down in string theory.

**String Theory and Branes**

by **Neil Lambert** - **King's College London** , **2010**
