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

   Författare :Johan Engquist; Joseph Minahan; Charlotte Kristjansen; Uppsala universitet; []
   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; Physics; 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.

3. 2. Perturbative Aspects of Supersymmetric Yang-Mills Theory on T3

   Författare :Fredrik Ohlsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is concerned with perturbative aspects of supersymmetric Yang-Mills theory in a space-time of the form T3xR, in the regime where the gauge coupling is weak. Wave functions of vacuum states of super Yang-Mills theoriesare supported on the moduli space of flat connections, and we consider a semi-classical treatment of such theories, obtained by expanding the fields around some normalizable zero energy background field configuration.

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

   Författare :Olof Ohlsson Sax; Joseph A. Minahan; Gianluca Grignani; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; String theory; AdS CFT correspondence; Integrable field theory; Mathematical physics; 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. 4. 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

7. 5. Color-Kinematics Duality and Gravitational Waves

   Författare :Maor Ben-Shahar; Henrik Johansson; Jan Plefka; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum field theory; gravitational waves; scattering amplitudes; Theoretical Philosophy; Teoretisk filosofi;

   Sammanfattning : Recent developments in theoretical physics have led to new insights for gauge theory and gravity scattering amplitudes.The color-kinematics duality, in particular, describes an intriguing set of identities obeyed by the kinematic numerators of gauge-theory scattering amplitudes, mirroring the Jacobi identity of the color factors.
