  1. 6. 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. 7. 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.

  4. 8. 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. 9. An Exploration of Q-Systems : From Spin Chains to Low-Dimensional AdS/CFT

    Författare :Simon Ekhammar; Dmytro Volin; Konstantin Zarembo; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum Spectral Curve; Integrability; AdS CFT; Physics and Astronomy specializing in Theoretical Physics; Fysik och astronomi med inriktning mot teoretisk fysik;

    Sammanfattning : The discovery of integrability in the planar limit of the AdS5/CFT4 correspondence has led to impressive progress in the study of string theory and four-dimensional N=4 Super-Yang-Mills. In particular, with the formulation of the Quantum Spectral Curve (QSC) the spectral problem is now solved. LÄS MER

  7. 10. Topics on D-branes and Holography

    Författare :Mikael Smedbäck; Joseph Minahan; Anton Alekseev; Paolo Di Vecchia; Uppsala universitet; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
