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.

These lecture notes provide a detailed introduction to the bosonic string and conformal field theory. The text is aimed at beginning graduate students. It assumes a working knowledge of quantum field theory and general relativity.

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.

We give an introductory review of topological strings and their application to various aspects of superstrings and supersymmetric gauge theories. This review includes developing the necessary mathematical background for topological strings.
