1. 11. 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.

3. 12. 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.

4. 13. 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

5. 14. Linking Chains Together : String Bits and the Bethe Ansatz

   Författare :Martin Lübcke; Konstantin Zarembo; Antti Niemi; Matthias Staudacher; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; theoretical physics; string theory; string bit; Bethe ansatz; Teoretisk fysik; Physics; Fysik;

   Sammanfattning : This thesis is divided into two parts. In the first part we focus mainly on certain aspects of the AdS/CFT correspondence. The AdS/CFT correspondence is a proposed duality between Type IIB superstring theory on AdS5 x S5 and N = 4 supersymmetric Yang-Mills theory. LÄS MER

7. 15. Quenched coupling and thermal behavior in the O(N) vector model

   Författare :Julius Engelsöy; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

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