**D-Branes, Tachyons, and String Field Theory**

by Washington Taylor, Barton Zwiebach

**Publisher**: arXiv 2004**Number of pages**: 104

**Description**:

In these notes we provide a pedagogical introduction to the subject of tachyon condensation in Witten's cubic bosonic open string field theory. We use both the low-energy Yang-Mills description and the language of string field theory to explain the problem of tachyon condensation on unstable D-branes.

**arXiv**

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.
