  1. 1. Topics in perturbation theory From IBP identities to integrands

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Alessandro Georgoudis; Uppsala universitet.; [2019]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Perturbation theory; Feynman Integrals; Integrable field theories; Correlation functions.; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : In this thesis we present different topics in perturbation theory. We start by introducing the method of integration by parts identities, which reduces a generic Feynman integral to a linear combination of a finite basis of master integrals. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Raul Pereira; Uppsala universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superstring theory; AdS CFT correspondence; Integrable field theories; Hexagon form factors; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : 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. LÄS MER

  3. 3. Dualities, Symmetries and Unbroken Phases in String Theory Probing the Composite Nature of the String

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Johan Engquist; Uppsala universitet.; [2005]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Theoretical Physics; String Theory; M-Theory; Higher Spin Gauge Theory; Super Yang-Mills Theory; Anti-de Sitter Spacetime; Singletons; Massless Higher Spin Gauge Fields; AdS CFT Correspondence; Spin Chains; Semiclassical Strings; Tensionless Limits; Conformal Symmetry; Supersymmetry; Higher Spin Gauge Symmetry; Integrability; Fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Sammanfattning : The thesis treats aspects of string/M-theory in anti-de Sitter spacetimes and their supersymmetric completions. By applying the AdS/CFT correspondence, as well as models of spin chains and singletons, we try to attain a better understanding of the underlying symmetries and the unbroken phases of string/M-theory.

  4. 4. Spins and Giants Fundamental Excitations in Weakly and  Strongly Coupled ABJM Theory

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Olof Ohlsson Sax; Uppsala universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; AdS CFT correspondence; Integrable field theory; NATURAL SCIENCES Physics Other physics Mathematical physics; NATURVETENSKAP Fysik Övrig fysik Matematisk fysik; Theoretical Physics; Teoretisk fysik;

    Sammanfattning : The discovery of integrability on both sides of the duality between planar N=4 super Yang-Mills theory and free type IIB string theory in AdS5 × S5 has lead to great progress in our understanding of the AdS/CFT correspondence. Similar integrable structures also appear in the more recent three-dimensional superconformal N=6 Chern-Simons-matter theory constructed by Aharony, Bergman, Jafferis and Maldacena (ABJM), as well as in its gravity dual, type IIA string theory on AdS4 × CP3.

  5. 5. Topics in Five Dimensional Supersymmetry and Topological Quantum Field Theories

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Luigi Tizzano; Uppsala universitet.; [2018]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Supersymmetric Quantum Field Theories; Topological Quantum Field Theories; String Theory.;

    Sammanfattning : We explore five-dimensional supersymmetric quantum field theories and topological quantum field theories. In five dimensions, we describe a framework to consistently define a supersymmetric theory on a curved spacetime manifold. LÄS MER
