Defects and Boundaries in Quantum Field Theories
(University of Waterloo, 2021-07-29)We discuss some aspects of defects and boundaries in quantum field theories (QFTs) and their applications in revealing non-perturbative aspects of QFTs in combination with other techniques, including integrability. ... -
Exact Results in Supersymmetric Gauge Theory
(University of Waterloo, 2016-08-30)Exact results are a key component for understanding any physical theory. Unfortunately in the context of quantum field theory (QFT) they are in general impossible to obtain, and we need some sort of approximations. However ... -
(Non)-Invertible Topology in Quantum Field Theory
(University of Waterloo, 2023-06-05)This thesis aims to highlight aspects of mathematics and physics that arise in topological field theories. We will consider invertible and noninvertible topological theories. In the former case, we compute the classification ... -
Non-perturbative aspects of gauge theories
(University of Waterloo, 2022-06-06)The purpose of this thesis is to establish some non-perturbative results in gauge theories in d<=4 spacetime dimensions. We generically refer to such theories as Quantum Chromodynamics (QCD). Gauge theories are asymptotically ... -
On Cohomological Algebras in Supersymmetric Quantum Field Theories
(University of Waterloo, 2019-08-16)In this thesis we compute certain supersymmetric subsectors of the algebra of observables in some QFTs and demonstrate an application of such computation in checking an instance of Holographic duality. Computing the algebra ... -
Topological Manipulations of Quantum Field Theories
(University of Waterloo, 2023-07-17)In this thesis we study some topological aspects of Quantum Field Theories (QFTs). In particular, we study the way in which an arbitrary QFT can be separated into “local” and “global” data by means of a “symmetry Topological ... -
Twisted Holography: The Examples of 4d and 5d Chern-Simons Theories
(University of Waterloo, 2022-09-29)Twisted holography is a duality between a twisted supergravity, and a twisted supersymmetric gauge theory living on the D-branes in the supergravity. The main objectives of this duality is the comparison between the algebra ...
