1. Topics on D-branes and Holography
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
2. Defects, renormalization and conformal field theory
Sammanfattning : 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.

3. A CFT perspective on holographic correlators
Sammanfattning : 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. LÄS MER
4. Topics in perturbation theory : From IBP identities to integrands
Sammanfattning : 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. LÄS MER
5. An Exploration of Q-Systems : From Spin Chains to Low-Dimensional AdS/CFT
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
