Observation of Resonant Electric DipoleDipole Interactions Between Cold Rydberg Atoms Using Microwave Spectroscopy
(University of Waterloo, 2006)This thesis reports the first observation of the resonant electric dipoledipole interaction between cold Rydberg atoms using microwave spectroscopy, the observation of the magnetic field suppression of resonant interactions, ... 
Octupolar Ordering in the b>0 BilinearBiquadratic Heisenberg Pyrochlore
(University of Waterloo, 20190125)We investigate the bilinearbiquadratic Heisenberg model on the pyrochlore lattice. While negative biquadratic couplings result in a firstorder transition into a nematic ordered state with spins aligned mutually ... 
An offlattice derivation and thermodynamic consistency consideration for the SanchezLacombe equation of state
(University of Waterloo, 20171109)The application of the SanchezLacombe equation of state (SLEOS) to homogeneous polymeric mixtures is requisite for the application of some types of SelfConsistent Field Theory (SCFT) to inhomogeneous mixtures. It has ... 
An OffLattice Model of the SanchezLacombe Equation of State for Polymers with Finite Flexibility
(University of Waterloo, 20200519)An extension to the offlattice Sanchez Lacombe equation of state is proposed by including internal degrees of freedom to account for the finite flexibility of polymer molecules. The extension allows polymer molecules to ... 
On an Electron Spin Resonance Spectrometer for Quantum Information Processing
(University of Waterloo, 20110124)Electron spins are an attractive candidate for an implementation of quantum information processing (QIP) due to high polarization, fast control and long coherence times. Control in electron spin resonance beneﬁts from ... 
On an Instrument for the Coherent Investigation of NitrogenVacancy Centres in Diamond
(University of Waterloo, 20130927)It is my hope that this thesis may serve as a guide for future students wishing to build a microscope from scratch. The design and construction of a scanning, confocal fluorescence microscope equipped with shaped microwave ... 
On Cohomological Algebras in Supersymmetric Quantum Field Theories
(University of Waterloo, 20190816)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 ... 
On Design and Testing of a Spectrometer Based on An FPGA Development Board for use with Optimal Control Theory and HighQ Resonators
(University of Waterloo, 20140224)Recent developments in quantum information processing have presented new and interesting ways to perform advanced algorithms and improve signal to noise ratios. Examples of these include optimal control theory pulse ... 
On Experimental Deterministic Quantum Computation with One Quantum Bit (DQC1)
(University of Waterloo, 20120327)Quantum information processors have the ability to drastically change our world. By manipulating bits of information ruled by the laws of quantum mechanics, computational devices can perform some computations that are ... 
On Experimental Quantum Communication and Cryptography
(University of Waterloo, 20120329)One of the most fascinating recent developments in research has been how different disciplines have become more and more interconnected. So much so that fields as disparate as information theory and fundamental physics ... 
On Free Space Quantum Key Distribution and its Implementation with a PolarizationEntangled Parametric Down Conversion Source
(University of Waterloo, 20070516)This thesis describes the deployment of a freespace quantum key distribution system across the University of Waterloo campus. The quantum key distribution system has the ability to provide unconditionally secure ... 
On Holographic NonLocal Operators and Multiple M2Branes Theories
(University of Waterloo, 20090612)Gaugestring duality has provided a powerful framework for the study of strongly coupled gauge theories and nonperturbative string models. This thesis analyzes the holographic description of nonlocal ... 
On Magic State Distillation using Nuclear Magnetic Resonance
(University of Waterloo, 20080125)Physical implementations of quantum computers will inevitably be subject to errors. However, provided that the error rate is below some threshold, it is theoretically possible to build fault tolerant quantum computers that ... 
On nearfreesurface dynamics of thin polymer films
(University of Waterloo, 20090424)Studies show that dynamical properties of ultrathin polymer films deviate from those of bulk materials. Despite some controversial issues, there is growing evidence indicating that the interfacial properties play a key ... 
On singlecrystal solidstate NMR based quantum information processing
(University of Waterloo, 20100519)Quantum information processing devices promise to solve some problems more efficiently than their classical counterparts. The source of the speedup is the structure of quantum theory itself. In that sense, the physical ... 
On the Classification of the Rseparable webs for the Laplace equation in E^3
(University of Waterloo, 20080429)In the first two Chapters I outline the theory and background of separation of variables as an ansatz for solving fundamental partial differential equations (pdes) in Mathematical Physics. Two fundamental approaches will ... 
On The Origin of Cold Molecular Gas In Giant Elliptical Galaxies
