String Theory - IoP - University of Amsterdam.
String Theory. String theory is the most promising theory that unifies all particles and forces in nature, including gravity, in a way consistent with the laws of quantum mechanics and relativity. String theory answers fundamental questions about the symmetries of nature, the quantum behavior of black holes, the existence and breaking of.
We are excited to announce that the 50th edition of the British Universities Summer School in Theoretical Elementary Particle Phyiscs (BUSSTEPP) will be held at QMUL Aug. 24 - Sep. 4, 2020.
The program consists of a series of short courses on advanced topics in String and Field Theory. The aim of these courses is not to offer a systematic introduction to basic material, but rather to help fill the gap between traditional PhD courses and the knowhow that is required for day-to-day research.

An Introduction to String Theory Kevin Wray 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 University of Amsterdam. We have also drawn on some ideas from the books String Theory and.

The intersection of string theory with cosmology is unavoidable in the early universe, and its exploration may shine light on both fields. In this thesis, three papers at this intersection are presented and reviewed, with the aim of providing a thorough and pedagogical guide to their results. First, we address the longstanding problem of finding a string theory realisation of the axion. Using.
This thesis explores the geometry of string theory backgrounds and the non-geometric features of string theory that arise due to T-duality. For this reason, it is divided into two complementary parts. Part I deals with the superalgebras of symmetries of string theory and M-theory backgrounds, the so-called Killing superalgebras. It is shown.
String theory, over its near five decade history, has attracted a great deal of controversy, which continues to evolve to the present day. The string theory controversy has novel aspects which highlight how contemporary science continues to develop. Those novel aspects include: non-empirical scientific methodologies and theory appraisal; a negotiation of the boundary between science and non.
In this thesis, three papers at this intersection are presented and reviewed, with the aim of providing a thorough and pedagogical guide to their results. First, we address the longstanding problem of finding a string theory realisation of the axion. Using warped compactifications in heterotic string theory, we show that the axion decay.

This thesis is a study of two dimensional noncritical string theory. The main tool which is used, is the matrix model. Introductions to both the Liouville model and its matrix model formulation are included. In particular the special states are discussed. Some calculations of partition functions on genus one using field theory techniques are given. Nonperturbative issues and string theory at.
Our new research training group RTG 2575 “Rethinking Quantum Field Theory” was approved by the German Research Foundation. We will start a PhD program at Humboldt University in April 2020 focusing on a broad education in modern aspects of quantum field theory and joint trainings for the next generation of quantum field theorist.
