D-Branes, Tachyons, and String Field Theory
by

Publisher: arXiv
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.

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.
