  2. 1. Correlation Functions in Integrable Theories : From weak to strong coupling

    Author : Raul Pereira; Joseph Minahan; Sergey Frolov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superstring theory; AdS CFT correspondence; Integrable field theories; Hexagon form factors; Theoretical Physics; Teoretisk fysik;

    Abstract : The discovery of integrability in planar N=4 super Yang-Mills and ABJM has enabled a precise study of AdS/CFT. In the past decade integrability has been successfully applied to the spectrum of anomalous dimensions, which can now be obtained at any value of the coupling. READ MORE

  4. 2. Supersymmetric Geometries in Type IIA Supergravity

    Author : Christian von Schultz; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flux compactifications; Supergravity; Supersymmetry; Superstring vacua;

    Abstract : Supergravity theory is any supersymmetric theory with a local supersymmetry parameter. This thesis undertakes the study of type IIA supergravity, a supergravity theory in ten dimensions associated with type IIA string theory. READ MORE

  5. 3. On string integrability : A journey through the two-dimensional hidden symmetries in the AdS/CFT dualities

    Author : Valentina Giangreco Marotta Puletti; Konstantin Zarembo; Gleb Arutyunov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; String Theory; AdS-CFT correspondence; Integrable Field theory; Sigma models; S-matrix; Factorized Scattering; Physics; Fysik; Mathematical physics; Matematisk fysik; Theoretical Physics; teoretisk fysik;

    Abstract : One of the main topics in the modern String Theory are the conjectured string/gauge (AdS/CFT) dualities. Proving such conjectures is extremely difficult since the gauge and string theory perturbative regimes do not overlap. In this perspective, the discovery of infinitely many conserved charges, i.e. READ MORE

  6. 4. Strings, Branes and Symmetries

    Author : Anders Westerberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lie-algebra cohomology; Reggeon vertices; extended objects; string theory; p -branes; current algebra; supersymmetry; sewing; pseudodifferential operators; D-branes;

    Abstract : Recent dramatic progress in the understanding of the non-perturbative structure of superstring theory shows that extended objects of various kinds, collectively referred to as p-branes, are an integral part of the theory. In this thesis, comprising an introductory text divided in two parts and seven appended research papers (Papers I-VII), we study various aspects of p-branes with relevance for superstring theory.

  7. 5. Linking Chains Together : String Bits and the Bethe Ansatz

    Author : Martin Lübcke; Konstantin Zarembo; Antti Niemi; Matthias Staudacher; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; string bit; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

    Abstract : This thesis is divided into two parts. In the first part we focus mainly on certain aspects of the AdS/CFT correspondence. The AdS/CFT correspondence is a proposed duality between Type IIB superstring theory on AdS5 x S5 and N = 4 supersymmetric Yang-Mills theory. READ MORE
