Bootstrapping Quantum Field Theories
(University of Waterloo, 2024-01-23)This thesis compiles a few developments on the S-matrix bootstrap, conformal field theory, and integrability in N = 4 SYM. After an introduction contextualizing the various works that compose this thesis, we present a ... -
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. ... -
Design and Implementation of an Entanglement Harvesting Experiment With Superconducting Flux Qubits
(University of Waterloo, 2022-05-16)Recent studies in relativistic quantum information have predicted that it is possible to entangle two qubits tunably coupled to the same quantum field in its vacuum state, by allowing the qubits to couple to the field ... -
Entanglement in Non-inertial Frames
(University of Waterloo, 2008-09-19)This thesis considers entanglement, an important resource for quantum information processing tasks, while taking into account the theory of relativity. Not only is this a more complete description of quantum information, ... -
Exact results in QFT: Minimal Areas and Maximal Couplings
(University of Waterloo, 2016-09-14)This thesis is devoted to a two-pronged study of non-perturbative quantum field theory. In Part I we focus on the four-dimensional super conformal $\mathcal{N}=4$ Yang Mills theory. We compute smooth Wilson loops and ... -
Explorations in the Conformal Bootstrap
(University of Waterloo, 2017-07-19)We investigate properties of various conformally invariant quantum systems, especially from the point of view of the conformal bootstrap. First, we study twist line defects in three-dimensional conformal field theories. ... -
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 ... -
Scattering Equations and S-Matrices
(University of Waterloo, 2015-06-25)We introduce a new formulation for the tree-level S-matrix in theories of massless particles. Sitting at the core of this formulation are the scattering equations, which yield a map from the kinematics of a scattering ... -
The Unruh-DeWitt Detector Model: Modified Dispersion and Nonlinear Couplings
(University of Waterloo, 2021-09-30)In this work, we employ the Unruh-DeWitt (UDW) detector model to various ends. We present applications of this relativistic detector model to quantum optics, including decoherence in optical cavities and non-linear quantum ...
