Emergent Matter of Quantum Geometry
(University of Waterloo, 2009-08-14)This thesis studies matter emergent as topological excitations of quantum geometry in quantum gravity models. In these models, states are framed four-valent spin networks embedded in a topological three manifold, and ... -
Emulation of Anyonic Statistics using High-Fidelity NMR Quantum Information Processing (QIP) Techniques
(University of Waterloo, 2015-09-30)NMR control techniques have made many important contributions in developing set of tools for optimal quantum control, ranging from spin echo to dynamical decoupling. Using such optimal quantum control techniques, the ... -
Engineering Effective Hamiltonians for Magnetic Resonance
(University of Waterloo, 2019-07-22)Effective Hamiltonian engineering is a powerful technique that utilises time-dependent perturbation theory to suppress or enhance certain effects that arise from otherwise weak Hamiltonian terms, when an experimenter ... -
Enhanced Dynamics at the Free Surface of a Molecular Glass Film
(University of Waterloo, 2010-10-07)In this thesis we describe two separate experiments involving the use of gold nanoparticles. The first experiment looks at the use of gold nanoparticles as a localized heat source and the potential application as a cancer ... -
Enhanced photo-stability of inverted organic solar cells via using polyethylenimine in the electron extraction layers
(Elsevier, 2019-10)The influence of using Polyethylenimine (PEI) in the electron extraction layers (EELs) on the photo-stability of inverted organic solar cells (OSCs) is investigated. Results show that introducing PEI in the commonly used ... -
ENHANCEMENT OF RYDBERG ATOM INTERACTIONS USING DC AND AC STARK SHIFTS
(University of Waterloo, 2010-05-19)This thesis reports the use of both dc and ac electric fi eld induced resonant energy transfer, RET, between cold Rydberg atoms as a useful tool for enhancement of interatomic interactions. A general technique for laser ... -
Entanglement Entropy of Scalar Fields in Causal Set Theory
(University of Waterloo, 2017-08-15)Entanglement entropy is now widely accepted as having deep connections with quantum gravity. It is therefore desirable to understand it in the context of causal sets, especially since they provide the UV cutoff needed to ... -
Entanglement Harvesting and Divergences in Unruh-DeWitt Detector Pairs
(University of Waterloo, 2017-08-28)We analyze correlations between pairs of detectors quadratically coupled to real and complex scalar bosonic fields in 3+1 dimensions. This is a first step toward studying the entanglement structure of the fermionic ... -
Entanglement in Non-inertial Frames
(University of Waterloo, 2008-09-19)This thesis considers entanglement, an important resource for quantum information processing tasks, while taking into account the theory of relativity. Not only is this a more complete description of quantum information, ... -
Entanglement quantification and quantum benchmarking of optical communication devices
(University of Waterloo, 2012-04-27)In this thesis, we develop a number of operational tests and tools for benchmarking the quantum nature of optical quantum communication devices. Using the laws of quantum physics, ideal quantum devices can fundamentally ... -
Entropic segregation of short polymers to the surface of a polydisperse melt
(Springer, 2017)Chain ends are known to have an entropic preference for the surface of a polymer melt, which in turn is expected to cause the short chains of a polydisperse melt to segregate to the surface. Here, we examine this entropic ... -
Entropically Driven Formation of Hierarchically Ordered Nanocomposites
(American Physical Society, 2002)Using theoretical models, we undertake the first investigation into the rich behavior that emerges when binary particle mixtures are blended with microphase-separating copolymers. We isolate an example of coupled self-assembly ... -
Equilibrium Phase Behaviour of Liquid Crystalline Polymer Brushes
(University of Waterloo, 2019-08-29)Using self-consistent field theory of worm-like chains with Maier-Saupe interactions we study the equilibrium phase behaviour of liquid crystalline (LC) polymer brushes. In a good solvent the brush extends out normal to ... -
Error characterization and quantum control benchmarking in liquid state NMR using quantum information processing techniques
(University of Waterloo, 2008-09-12)Quantum information processing has been the subject of countless discoveries since the early 1990's. It is believed to be the way of the future for computation: using quantum systems permits one to perform computation ... -
Estimating and Mitigating Effects of Space Radiation Damage in Single-Photon Avalanche Diodes
(University of Waterloo, 2022-02-01)Satellite-based quantum key distribution necessitates practical and robust detectors capable of withstanding the harsh environment of space. Single-photon avalanche diodes (SPADs) have been shown to fulfill the required ... -
An estimation theoretic approach to quantum realizability problems
(University of Waterloo, 2023-09-27)This thesis seeks to develop a general method for solving so-called quantum realizability problems, which are questions of the following form: under which conditions does there exist a quantum state exhibiting a given ... -
Evaluating Characteristic Parameters for Carbon Dioxide in the Sanchez−Lacombe Equation of State
(American Chemical Society, 2017)For many different pure substances, large numbers of competing characteristic parameter sets exist in the literature for the Sanchez−Lacombe equation of state. This is due in part to differing research requirements or ... -
Evaluation and Comparison of Two Novel Non-Platinum-Based Antitumor Agents on Pancreatic Cancer and Triple-Negative Breast Cancer
(University of Waterloo, 2022-10-03)Cancer is one of the leading causes threatening human life. People suffering from pancreatic cancer and triple-negative breast cancer (TNBC) have particularly low survival rate among all cancer types. The novel non-platinum ... -
