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 ... -
Constructing Exact Correlators In N=4 SYM Using Integrability
(University of Waterloo, 2019-08-09)This thesis is devoted to the study of correlation functions in N = 4 superconformal Yang- Mills theory. We focus on a class of four point functions for which we achieve formal results at finite coupling and explicit ... -
Continuous Tensor Networks, Conformal Field Theory and Holography
(University of Waterloo, 2020-07-23)Tensor network methods are playing a central role in multiple disciplines of modern quantum physics, such as condensed matter physics, quantum information and quantum gravity. Based on renormalization group (RG) ideas, ... -
Correlation Functions of Heavy Operators in AdS/CFT
(University of Waterloo, 2024-04-15)In this thesis we investigate the holographic dual description of correlation functions of heavy operators in conformal field theory. These heavy operators have scaling dimension that scales with the CFT central charge in ... -
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. ... -
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. ... -
Holographic Experiments on Defects
(University of Waterloo, 2009-09-03)Using the AdS/CFT correspondence, we study the anisotropic transport properties of both supersymmetric and non-supersymmetric matter fields on (2+1)-dimensional defects coupled to a (3+1)-dimensional N=4 SYM "heat bath". ... -
Renormalization, Entanglement and Continuous Tensor Networks
(University of Waterloo, 2020-07-07)The study of the ground states of local Hamiltonians in quantum many-body and quantum field theoretic systems is a source of many research problems of great complexity. Almost in its entirety, this thesis deals with ... -
Tensor networks, quantum spin chains, and quantum field theory
(University of Waterloo, 2020-07-07)Understanding the universality class of continuous phase transition is of central importance in condensed matter physics. In one spatial dimension, the universal properties are encoded in the conformal field theory (CFT), ...
