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 course will introduce string theory, which has become the dominant framework for a complete theory of all physical phenomena. As such it is in some sense a course to introduce the modern view of particle physics at its most fundamental level.

Basic aspects of non-perturbative string theory are discussed. The topics include test of duality symmetries based on the analysis of the low energy action and the spectrum of BPS states, relationship between different duality symmetries, etc.

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.

The text covers the basic concepts of modern string theory: covariant and light-cone quantisation of bosonic and fermionic strings, geometry and topology of string world-sheets, vertex operators and string scattering amplitudes, etc.
