  1. 1. Twisting it up the Quantum Way : On Matrix Models, q-deformations and Supersymmetric Gauge Theories

    Author : Rebecca Lodin; Maxim Zabzine; Taro Kimura; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Matrix models; Virasoro constraints; Virasoro algebra; W algebra; q-deformations; Supersymmetric gauge theories; Theoretical Physics; Teoretisk fysik;

    Abstract : The mathematical framework which quantum field theory constitutes has been very successful in describing nature. As an extension of such a framework, the idea of supersymmetry was introduced. This greatly simplified the mathematical description of the theories, making them more tractable. READ MORE

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

    Author : Johan Engquist; Joseph Minahan; Charlotte Kristjansen; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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; Physics; Fysik;

    Abstract : 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. Aspects of vacuum moduli in string theory

    Author : Matthew Magill; Magdalena Larfors; James Sparks; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; string compactifications; g structures; homological algebra; Theoretical Physics; Teoretisk fysik;

    Abstract : In this thesis we explore geometric aspects of the space of vacua in supersymmetric string compactifications. More specifically, we will look at heterotic strings compactified on Calabi-Yau manifolds and, separately, G2 structure manifolds. READ MORE

  5. 5. Group Extensions, Gerbes and Twisted K-theory

    Author : Pedram Hekmati; Jouko Mickelsson; Jürgen Fuchs; KTH; []
