Geometry of Quantum States from Symmetric Informationally Complete Probabilities
(University of Waterloo, 2013-08-06)It is usually taken for granted that the natural mathematical framework for quantum mechanics is the theory of Hilbert spaces, where pure states of a quantum system correspond to complex vectors of unit length. These vectors ... -
Gravitational Thermodynamics: From Black Holes to Holography
(University of Waterloo, 2021-06-01)The subject of gravitational thermodynamics lies at the center of numerous fields of study, many of which may seem disconnected, yet have proven to be deeply entwined. This thesis examines two primary facets of this subject, ... -
Group-finding with photometric redshifts: The Photo-z Probability Peaks algorithm
(University of Waterloo, 2010-01-25)We present a galaxy group-finding algorithm, the Photo-z Probability Peaks (P3) algorithm, optimized for locating small galaxy groups using photometric redshift data by searching for peaks in the signal-to-noise of the ... -
Growth of Silicon Nanowire Mechanical Oscillators for Force-Detected Magnetic Resonance Measurements
(University of Waterloo, 2018-01-19)This thesis describes two ways to grow silicon nanowires with the catalyst gold (Au) by Chemical Vapor Deposition (CVD) system. One way to prepare catalyst is drop-casting gold nanoparticles solution, the other is making ... -
Guiding our interpretation of quantum theory by principles of causation and inference
(University of Waterloo, 2021-07-07)A key aim of quantum foundations is to characterize the sense in which nature goes beyond classical physics. Understanding nonclassicality is one of our best avenues towards finding a satisfactory interpretation of quantum ... -
¹H MAS NMR Spectral Coalescence of Water and Hydroxyl Resonances in MCM-41
(University of Waterloo, 2011-09-01)Solid state ¹H MAS NMR spectroscopy was used to investigate the temperature and hydration dependance of water and hydroxyl proton spectra of hydrated mesoporous MCM-41. The NMR spectra show a complex peak structure, with ... -
Hall Resistance Characterization of Thermoelectric Materials; Subgap Leakage Measurement of Josephson Junctions
(University of Waterloo, 2020-06-01)The thesis has two parts. The first part is the Hall measurement of thermoelectric materials which are promising energy sources in the future. By characterizing the Hall resistance at different environments, their charge ... -
Heralding Photonic Qubits for Quantum Communication
(University of Waterloo, 2016-01-22)Quantum communication attempts to harness the unique rules of quantum mechanics to perform communication tasks that are difficult or impossible using classical rules. To realize these benefits, information must be carried ... -
A Herschel/HIFI study of Water in Two Intermediate-Mass Star Forming Regions: Vela IRS 17 and Vela IRS 19
(University of Waterloo, 2013-05-27)While the single core accretion model for low mass star formation is well developed, it cannot simply be extended into the high mass star formation regime where clustered star formation dominates. The study of intermediate-mass ... -
Heterogeneous Particles with Isotropic Interactions: Investigating the Effect of Multiple Species and Particle Size Disparity on Self-Assembly
(University of Waterloo, 2015-10-21)There is much interest in using self-assembly to build materials at the microscopic level by using soft matter systems such as block copolymers and DNA coated colloids. Self-consistent field theory (SCFT) has seen much ... -
Heterostructure development and quantum control for semiconductor qubits
(University of Waterloo, 2022-01-04)States of confined electrons in semiconductors are promising candidates for quantum bits with high controllability, scalability, and coherence. Particularly, spin quantum dots offer direct integration with the modern MOS ... -
High Rate, Large Area Laser-assisted Chemical Vapor Deposition of Nickel from Nickel Carbonyl
(University of Waterloo, 2009-05-01)High-power diode lasers (HPDL) are being increasingly used in industrial applications. Deposition of nickel from nickel carbonyl (Ni(CO)4) precursor by laser-induced chemical vapor deposition (CVD) was studied with emphasis ... -
HIGH RESOLUTION MICROWAVE SPECTROSCOPY OF ULTRA COLD RYDBERG ATOMS AS A PROBE OF ELECTRIC AND MAGNETIC FIELDS
(University of Waterloo, 2003)In highly excited Rydberg atoms, the excited electron is in a large, loosely bound orbit. Hence, in contrast with the ground states, the Rydberg states are very sensitive to external electric field and can be ionized in ... -
Higher dimensional Taub-NUT spaces and applications
(University of Waterloo, 2006)In the first part of this thesis we discuss classes of new exact NUT-charged solutions in four dimensions and higher, while in the remainder of the thesis we make a study of their properties and their possible applications. ... -
Hillock-free and atomically smooth InSb QWs grown on GaAs substrates by MBE

Hodge Theory for Geometrically Frustrated Magnetism
(University of Waterloo, 2022-09-29)We present an analytical formalism based on the concept of discrete differential forms and Hodge theory as a framework for understanding geometrically frustrated magnetism. The primary insight is to treat spins as a 1-form ... -
Holographic Correspondence and Exploring New Regimes of AdS/CFT Duality
(University of Waterloo, 2013-06-21)We aim to have a comprehensive understanding of holographic correspondence and to demonstrate how the holographic correspondence (or renormalization) can be applied. Thus this thesis is divided into two parts. The first ... -
Holographic Entanglement Entropy: RG Flows and Singular Surfaces
