2. 1. 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

4. 2. Defects, renormalization and conformal field theory

   Author : Alexander Söderberg Rousu; Agnese Bissi; Pedro Liendo; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; defects; boundaries; replica twist defect; conformal field theory; quantum field theory; Coleman-Weinberg mechanism; renormalization group flows; Theoretical Physics; Teoretisk fysik;

   Abstract : Defects in quantum field theories appear in many different contexts and are of great physical interest. Among other things, defects are used to describe the Kondō effect in condensed matter, confinement in quantum chromodynamics, Rényi entropy in quantum information and cosmic strings in string theory.

5. 3. A CFT perspective on holographic correlators

   Author : Giulia Fardelli; Agnese Bissi; Paul Heslop; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superconformal field theories; Analytic bootstrap; Correlation functions; Quantum gravity; Theoretical Physics; Teoretisk fysik;

   Abstract : Conformal symmetry is ubiquitous in physics. It emerges in a variety of situations from critical phenomena, through condensed matter systems and jets at the LHC to string theory. Conformal field theories (CFTs) describe the universal behavior underlying these very different setups. READ MORE

6. 4. Topics in perturbation theory : From IBP identities to integrands

   Author : Alessandro Georgoudis; Joseph A. Minahan; Tristan McLoughlin; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Perturbation theory; Feynman Integrals; Integrable field theories; Correlation functions.; Theoretical Physics; Teoretisk fysik;

   Abstract : In this thesis we present different topics in perturbation theory. We start by introducing the method of integration by parts identities, which reduces a generic Feynman integral to a linear combination of a finite basis of master integrals. READ MORE

7. 5. An Exploration of Q-Systems : From Spin Chains to Low-Dimensional AdS/CFT

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

   Abstract : 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. READ MORE
