quantum information and more. There are several reasons for this. First, string theory is capable of generating a vast number of quantum field theories (QFTs) in various dimensions. There are five types of string theories - Type I, IIA, IIB, Heterotic SO(32), and E8 × E8 - and M-theory is the limit of large dilaton expectation va
Point particle propagation defines standard geometry. String propaga- tion vis 2d CFTs provides an infinite dimensional generalization: ...
Abstract: This set of notes is based on the course “Introduction to String Theory” which was taught by Prof. Kostas Skenderis in the spring of 2009 at the ...
Quantum string theory is written as integrable analytic geometry on the universal moduli space of Riemann surfaces. 1. Introduction. In this lecture I describe ...
The book contains explanations and descriptions of many details that have been deliberately. (and, I suspect, at times inadvertently) swept under a very large ...

Why do quantum strings demand a particular spacetime dimension? • Why is string theory a theory of quantum gravity? • Why does string theory ...
So, granting that string theory makes sense, it is actually a solution to a long-standing problem (!!): Find a quantum mechanical theory that ...
Abstract We give a lightning introduction to critical string theory, including the 26-dimensional bosonic string, the 10-dimensional superstrings and heterotic strings with and without spacetime supersymmetry. We also discuss open strings and D-branes, as well as the orientifold constructions, in ten dimensions.
A good example is the surface of a sphere – close up it looks like a flat 2d space, but globally it's very different. It turns out that you can formulate ...
This course requires knowledge of quantum mechanics. If you know about the har- monic oscillator, fermions and spin, you should be good. We also require some ...
Here, we discuss two examples for the generation of such hierarchies that cannot be explained in purely four-dimensional quantum field theory.
The purpose of this article is to explain some of the unusual features of relativistic strings and to show one way in which string theory may describe the ...
It is possible to construct actions for heterotic and type II string field theory, but the theory contains an additional set of particles which are free. These ...
In addition, string theory has exerted a dramatic influence on developments in contemporary mathematics, ranging from mirror symmetry and enumerative geometry ...
So far, we have found two superstring theories in ten dimensions: type IIA and type IIB string theory, which are related by T-duality. These nicely correspond ...
The purpose of this book is to provide an introduction to the various methods that have been developed in string theory for condensed matter applications, and ...
Write down the mode expansion describing an open string stretched between two parallel. Dp-branes. Interpret the result. 7a. Given the canonical commutation ...
String field theory is a quantum field theory with infinite number of fields in which perturbative amplitudes are computed by summing over Feynman diagrams.
