TaubNUT Spacetime in the (A)dS/CFT and MTheory
(University of Waterloo, 2005)In the following thesis, I will conduct a thermodynamic analysis of the TaubNUT spacetime in various dimensions, as well as show uses for TaubNUT and other HyperKahler spacetimes. <br /><br /> Thermodynamic analysis ... 
Techniques for Coherent Control of Effective PhotonPhoton Interactions at Low Light Levels
(University of Waterloo, 20190201)This thesis proposes improvements on techniques for the coherent control of photonphoton interactions mediated by a cloud of cold atoms. Atoms cooled and trapped in a MOT can be loaded into a hollow, photonic crystal ... 
Temperature Effects in Optical Fiber Dispersion Compensation Modules
(University of Waterloo, 20130905)This thesis presents the results for the temperature variation of the Differential Group Delay (DGD) measurements of a Dispersion Compensation Module (DCM) and interprets the results with a theoretical DGD model based on ... 
Temporal Dynamics of Polarization and Polarization Mode Dispersion and Influence on Optical Fiber Systems
(University of Waterloo, 20130829)This thesis examines polarization and polarization mode dispersion (PMD) dynamics in optical fibers as well as the evaluation of probability density functions and bit error rates in a realistic wavelength division multiplexed ... 
Tensor Networks and the Renormalization Group
(University of Waterloo, 20180824)Tensor networks are a class of methods for studying manybody systems. They give a geometrical description of the internal structure of manybody states, operators, and partition functions, that can be used to implement ... 
Tensor networks, quantum spin chains, and quantum field theory
(University of Waterloo, 20200707)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), ... 
Testing classical and quantum theory with single photons
(University of Waterloo, 20180119)To date, quantum theory is the most successful physical theory that has been discovered. However, there is still the possibility that an inconsistency between experimental observations and the predictions of quantum theory ... 
Testing the Universality of Entropic Segregation at Polymer Surfaces
(2018)This study addresses entropic segregation effects at the surfaces of monodisperse and bidisperse melts. For the monodisperse melts, we focus on the segregation of chain ends to the surface, and for the bidisperse melts, ... 
Theoretical Analysis of A Protected Superconducting Qubit
(University of Waterloo, 20151102)In the past few decades, quantum computation has become an active area of research due to prospects to execute highefficiency quantum algorithms. Quantum algorithms promise to accelerate many practical computation problems, ... 
Theoretical studies of frustrated magnets with dipolar interactions
(University of Waterloo, 20091218)Several magnetic materials, in the first approximation, can be described by idealised theoretical models, such as classical Ising or Heisenberg spin systems, and, to some extent, such models are able to qualitatively expose ... 
Theoretical study of nonrelativistic electron dynamics under intense laser fields
(University of Waterloo, 20120409)Strong field approximation (SFA) is the most important approximation in the analytical theory of intense laser matter interaction. Based on SFA many analytical theories have been developed such that a broad spectrum ...
