1H MAS NMR Study of Water on PdMCM41
(University of Waterloo, 20150618)Hydrogen spillover represents one of the most promising avenues to achieve hydrogen storage at the density required for transportation applications. The spillover phenomenon, however, is a topic of much debate, with many ... 
A 4d Lorentzian Spin Foam Model With Timelike Surfaces
(University of Waterloo, 20101007)We construct a 4d Lorentzian spin foam model capable of describing both spacelike and timelike surfaces. To do so we use a coherent state approach inspired by the Riemannian FK model. Using the coherent state method we ... 
Above Bandgap Hyperpolarization Mechanism in Isotopically Purified Silicon and Optimal Bayesian Experiment Design for $T_1$ Estimation
(University of Waterloo, 20180524)This thesis is concerned with the mechanism underlying the above bandgap illumination Dynamic Nuclear Polarization (DNP) of phosphorus donors in isotopically purified silicon28. Two proposed DNP models are introduced and ... 
Abundance Matching with the Galaxies of the Virgo Cluster and the StellartoHalo Mass Relation
(University of Waterloo, 20120927)Using data from the Next Generation Virgo Cluster Survey and highresolution simulations of Virgo clusterlike halos, we determine the stellartohalo mass relation (SHMR) for subhalos, using the technique of abundance ... 
Achievable Polarization for HeatBath Algorithmic Cooling
(University of Waterloo, 20150817)Highly pure quantum states play a central role in applications of quantum information science, both as initial states for quantum algorithms and as resources for quantum error correction. Controlled preparation of pure ... 
AluminiumPalladium Transition Edge Sensors
(University of Waterloo, 20080915)A superconducting Transition Edge Sensor (TES) can be used to make the most sensitive thermometer which operates in a very narrow temperature range. The thin film bilayer fabrication details are discussed as well as ... 
Amended Model of Large Scale Dark Matter Structure
(University of Waterloo, 20200903)Dark matter makes up around a quarter of the total energy density in the universe, but its identity remains elusive. Current ways of studying dark matter have centered around its macroscopic properties, such as density ... 
Analytical and Numerical Studies of 2D XY Models with Ring Exchange
(University of Waterloo, 20120831)In this thesis we take several different analytic and numerical approaches to studying the classical JK model. This model describes an interacting manybody system of spins with continuous symmetry which interact via ... 
An apparatus for studying interactions between Rydberg atoms and metal surfaces
(University of Waterloo, 20070927)A system suitable for studying interactions between ⁸⁷Rb Rydberg atoms and metal surfaces has been constructed. This thesis describes the design and construction of the apparatus, and some test results. Atoms in a vapor ... 
Application of the FlagState Squashing Model to Numerical Quantum Key Distribution Security Analysis
(University of Waterloo, 20200918)The squashing model proof technique is a powerful tool in proving security of quantum key distribution (QKD) protocols since it reduces the dimension of the associated computational problem from infinite to finite. In the ... 
Applications of Raman Spectroscopy
(University of Waterloo, 20140822)This thesis is devoted to exploring experimental applications of Raman spectroscopy. The ability of Raman spectroscopy to investigate the vibrational modes of a molecule was explored in several studies. The work included ... 
Applications of the Quantum Kernel Method on a Superconducting Quantum Processor
(University of Waterloo, 20200529)The widespread benefits of classical machine learning along with promised speedups by quantum algorithms over their best performing classical counterparts have motivated development of quantum machine learning algorithms ... 
Aspects of Quantum Field Theory with Boundary Conditions
(University of Waterloo, 20190802)This thesis has two modest goals. The primary goal is to deliver three results involving particle detectors interacting with a quantum field in presence of nontrivial boundary conditions (Dirichlet, Neumann, periodic; ... 
Assessing the Practicality of a Simple Multinode Quantum Repeater
(University of Waterloo, 20171025)This thesis assesses the theoretical performance of a realistic multinode quantum repeater that is implementable with current technology. A quantum repeater, by definition, allows for communication rates in a channel to ... 
Atomic Force Microscopy Study of Model Lipid Monolayers
(University of Waterloo, 20120926)Alzheimer's Disease (AD) is a neurodegenerative disorder that is prevalent among the elderly population. Aß protein has been heavily implicated in the pathogenesis of AD. This protein in its fibrillar form is a major ... 
Bichromatic dressing of Rydberg atoms and on the correctness of manymode Floquet theory
(University of Waterloo, 20200120)Manymode Floquet theory [T.S. Ho, S.I. Chu, and J. V. Tietz, Chem. Phys. Lett. 96, 464 (1983)] was designed as an extension of Floquet theory suitable for solving the timedependent Schrodinger equation with multiple ... 
Black Holes in PseudoTopological Gravity
(University of Waterloo, 20090805)In the following, we build on previous work done on higher derivative gravity, in particular Lovelock gravity. The latter is a family of theories in higher spacetime dimensions in which interactions involving higher ...
