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

    Författare :Raul Pereira; Joseph Minahan; Sergey Frolov; Uppsala universitet; []
    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. 2. Quivers, superconformal field theories and higher symmetries

    Författare :Robert Moscrop; Michele Del Zotto; Johannes Walcher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum field theory; Supersymmetry; Conformal field theory; Quivers; Seiberg-Witten theory; Geometric engineering; Higher symmetries; Theoretical Physics; Teoretisk fysik; Machine learning; Maskininlärning;

    Sammanfattning : Quantum field theory (QFT) currently provides our best description of the natural world. Over the past century, it has been able to accurately reproduce many experimental results to an astonishing degree of accuracy and predict the existence of new particles. Despite this, QFT suffers from several mathematical problems. LÄS MER

  4. 3. Topics in Five Dimensional Supersymmetry and Topological Quantum Field Theories

    Författare :Luigi Tizzano; Maxim Zabzine; Anton Kapustin; Uppsala universitet; []
    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

  5. 4. Emergent spacetime from simple field theories

    Författare :Julius Engelsöy; Bo Sundborg; Sumit R. Das; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AdS CFT; thermalization; quench; large N singlet models; emergent spacetime; fysik; Physics;

    Sammanfattning : Thermalization is an elusive phenomenon in quantum mechanics. Since according to the AdS/CFT correspondence, a black hole in the bulk spacetime is dual to a thermal state in the boundary CFT, thermalization in the CFT is dual to black hole formation in AdS. LÄS MER

  7. 5. Topics in perturbation theory : From IBP identities to integrands

    Författare :Alessandro Georgoudis; Joseph A. Minahan; Tristan McLoughlin; Uppsala universitet; []
    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
