Topological Strings and their Physical Applications

Publisher: arXiv 2005
Number of pages: 82
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, such as the notions of Calabi-Yau manifold and toric geometry, as well as physical methods developed for solving them, such as mirror symmetry, large N dualities, the topological vertex and quantum foam.

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.

Introduction to 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.

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.

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.
