A Characterization Theorem for Local Operators in Factorizing Scattering Models
(2013-01-10)In quantum field theory, the rigorous construction of local observables in the presence of nontrivial interaction is a crucial problem. In a class of integrable quantum field theories, a very abstract existence proof ... -
AdS/CFT Holography of the O(N)-symmetric $\phi^4$ Vector Model
(2008-01-10)We study the AdS/CFT correspondence at the example of the renormalization group IR and UV fixpoint theories of a Euclidean O(N)-symmetric vector field theory with $(\underline \phi^2)^2$ interaction in 2 dimensions. These ... -
Braided Actions of DHR Categories and Reconstruction of Chiral Conformal Field Theories
(2016-10-18)Quantum Field Theory (QFT) is our modern understanding of particles and matter at small scales, where quantum behaviour replaces macroscopical phenomena, which are much closer to intuition, and dynamics is rather driven ... -
Constructive aspects of string-localized quantum field theory
(2022-05-03)String-localized quantum field theory (SLFT) as an alternative to gauge theory has been under investigation for the last decade because of its conceptual benefits. This thesis is dedicated to the development and investigation ... -
Local Extensions of Completely Rational Conformal Quantum Field Theories
(2011-07-29)In the present work we addressed several important problems regarding local extensions of chiral conformal quantum field theories. We showed that by methods from the algebraic approach the ... -
Modular structure of chiral Fermi fields in conformal quantum field theory
(2014-09-19)The following thesis deals with the modular theory of Fermi fields in low dimensions; in particular, making use of the algebraic approach to quantum field theory, we have investigated the behaviour of two- dimensional ... -
Structure of Coset models
(2003-07-15)We study inclusions of local, chiral, conformal quantum theories C which are contained in an ambient theory B and commute with another given subtheory A. These subtheories C are ... -
Superconformal Invariants and Correlation Functions
(2012-06-28)Results of the past decade on global conformal field theories within the framework of Wightman axioms raise the question of possible analogues for theories with superconformal symmetry. In this dissertation we establish ...
