2. 1. Supersymmetric Gauge Theories and Matrix Models

   Author : Rainer Heise; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; String theory; Effective field theory; Matrix model; Supersymmetric gauge theories;

   Abstract : We discuss recent developments in supersymmetric field theory due to the conjecture of Dijkgraaf and Vafa relating the effective superpotential of such theories to the computation of an associated matrix model. We give a short survey of N=1 supersymmetric gauge theories and state the conjecture. READ MORE

4. 2. 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.

5. 3. Supersymmetric Localization : A Journey from Seven to Three Dimensions

   Author : Konstantina Polydorou; Guido Festuccia; Elli Pomoni; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; Localization; Equivariant Cohomology; BPS Operators; Topological Field Theory; Equivariant Twisting; Theoretical Physics; Teoretisk fysik;

   Abstract : Quantum Field Theory has been a dominating framework in elementary particle physics during the last century. Within this framework, supersymmetric theories have attracted a lot of attention due to their mathematical structure, simplicity and insight into the problems of unification, dark matter and hierarchy.

6. 4. Localization, supersymmetric gauge theories and toric geometry

   Author : Jacob Winding; Maxim Zabzine; Sara Pasquetti; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmetry; gauge theory; localization; toric geometry; Theoretical Physics; Teoretisk fysik;

   Abstract : Gauge theories is one of the most pervasive and important subject of modern theoretical physics, and there are still many things about them we do not understand. In particular dealing with strongly coupled theories where normal perturbative techniques do not apply is a fundamental open problem. READ MORE

7. 5. Results in Localization for Supersymmetric Gauge Theories

   Author : Anastasios Gorantis; Joseph A. Minahan; Kimyeong Lee; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supersymmetric localization; Matrix models; Supersymmetric field theories; Cohomological field theories; Chiral algebras; Theoretical Physics; Teoretisk fysik;

   Abstract : The strong coupling dynamics of Quantum Field Theories with gauge symmetries constitutes a profound problem in Theoretical Physics. Supersymmetric theories offer rare instances where this elusive problem is tractable and can be a valuable source of information and intuition. READ MORE
