  2. 1. Aspects of Yang-Mills Theory : Solitons, Dualities and Spin Chains

    Author : Lisa Freyhult; Antti Niemi; Poul Damgaard; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Theoretical Physics; Field theory; String theory; Yang-Mills; Effective models; Supersymmetry; Solitons; Fermion number; Duality; AdS CFT correspondence; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

    Abstract : One of the still big problems in the Standard Model of particle physics is the problem of confinement. Quarks or other coloured particles have never been observed in isolation. Quarks are only observed in colour neutral bound states. The strong interactions are described using a Yang-Mills theory. READ MORE

  4. 2. Topics on D-branes and Holography

    Author : Mikael Smedbäck; Joseph Minahan; Anton Alekseev; Paolo Di Vecchia; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; D-branes; dualities; AdS CFT; spin chains; Bethe ansatz; boundary conformal field theory; conformal bootstrap; tachyon condensation; string field theory; loop quantum gravity; black holes; area spectrum; Hawking radiation; holographic principle; Teoretisk fysik; Physics; Fysik;

    Abstract : We discuss various aspects of D-branes in string theory and holography in string theory and loop quantum gravity.One way to study D-branes is from a microscopic perspective, using conformal field theory techniques. For example, we investigate the question of how D-branes can be introduced into orbifolded theories. READ MORE

  5. 3. D-instantons and Dualities in String Theory

    Author : Christoffer Petersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis we study non-perturbative aspects of string theory. We focus our analysis on D-instanton effects which play key roles in the context of dualities, moduli stabilization and phenomenology. READ MORE

  6. 4. 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 : 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; 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.

  7. 5. Organizational identity construction in family businesses a dualities perspective

    Author : Börje Boers; Leif Melin; Mattias Nordqvist; Majken Schultz; Thomas Zellweger; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This dissertation is about organizational identity construction with a dualities perspective. By taking a dualities perspective the focus shifts from assuming that organizational identity actually is in place towards organizational identity construction where identities are socially constructed.
