D-Branes, Tachyons, and String Field Theory
by Washington Taylor, Barton Zwiebach
Publisher: arXiv 2004
Number of pages: 104
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.

This is a pedagogical review article surveying the various approaches towards understanding gauge coupling unification within string theory. The author provides an overview of the different approaches that have been taken in recent years.

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.

This text provides some historical background and then reviews developments in string theory over the last twenty-five years. Both perturbative and non-perturbative approaches are surveyed and their impact on how we view quantum gravity is analysed.

An introduction to string theory, focusing on the Bosonic string, but treating the superstring as well. A number of appendices on more advanced topics are also provided, including an introduction to orientifolds in various brane configurations.
