Feasibility of Injecting Large Volumes of CO2 into Aquifers
(Elsevier, 2009-02)Although it is recognized that deep aquifers offer a very large potential storage capacity for CO2 sequestration it is not clear how to fill the storage with a large volume of CO2 in a relatively short period of time. The ... -
Feasibility of Testing the Event Formalism with Refractive Materials
(University of Waterloo, 2022-05-20)In this thesis, we evaluate the feasibility of verifying the effect of gravity on the quantum entanglement by simulating gravity’s effects with other physical systems. Specifically, we work in the framework of the Event ... -
Femtosecond Laser Induced Polyyne Formation
(University of Waterloo, 2010-10-01)Polyyne molecules were produced as a result of the femtosecond laser irradiation of liquid acetone (CH3)2CO and alkane molecules hexane C6H14 and octane C8H18 using 800 nm, 100 fs duration pulses. These polyynes have ... -
Femtosecond Time-Resolved Studies on the Reaction Pathways for the Generation of Reactive Oxygen Species in Photodynamic Therapy by Indocyanine Green
(University of Waterloo, 2008-09-12)Photodynamic therapy (PDT), which utilizes the combination of light and a photosensitizing drug to cause tissue damages, has emerged as a novel clinical approach for the treatment of numerous cancers, as well as some other ... -
Few Hole Quantum Dots in a Gated GaAs/AlGaAs Heterostructure
(University of Waterloo, 2019-06-24)This thesis presents a set of experiments that explore gate de ned hole quantum dots in the GaAs/AlGaAs heterostructure. These experiments explore the evolution of the quantum states of holes in a double quantum dot. The ... -
Few-Cycle Laser Pulse Generation and Characterization for Coulomb Explosion Imaging of Molecules
(University of Waterloo, 2020-01-22)Ultrashort pulses can induce coulomb explosions of molecules through which ionic fragments receive substantial momentum. These momenta, measured in coincidence, carry information about the molecule's initial geometry. ... -
Fiber Birefringence Modeling for Polarization Mode Dispersion
(University of Waterloo, 2007-01-17)This thesis concerns polarization mode dispersion (PMD) in optical fiber communications. Specifically, we study fiber birefringence, PMD stochastic properties, PMD mitigation and the interaction of fiber birefringence ... -
Field-Free Alignment and Strong Field Control of Molecular Rotors
(University of Waterloo, 2004)Methods of controlling molecular rotations using linearly polarized femtosecond and picosecond pulses are considered and analyzed theoretically. These laser pulses, typically in the infrared, are highly non-resonant ... -
Field-Orientation Coupling Effects in Nematic Liquid Crystal Cells
(University of Waterloo, 2019-10-23)Using the continuum Landau-de Gennes model for the nematic liquid crystal (NLC) phase, we study the equilibrium behaviour of nematic cells, accounting for the coupling between external fields and nematic order. This is ... -
Field-Sweep Control in Magnetic Resonance and k-space Analysis
(University of Waterloo, 2019-10-30)In a general magnetic resonance experiment, resonant radiofrequency or microwave fields are applied to an ensemble of electron or nuclear spins to determine their magnetic interactions with their local environment. These ... -
Flag fault-tolerant error correction for cyclic CSS codes
(University of Waterloo, 2018-06-20)Fault-tolerant quantum error correction (FTEC) protocol is one of the most important components for a fault-tolerant simulation of a quantum circuit. It helps prevent error accumulation during the process which may cause ... -
Flag Fault-Tolerant Error Correction with Qudits
(University of Waterloo, 2022-01-20)In this thesis, I explore fault-tolerant quantum error correction using qudits. I show that a specific flag-fault-tolerant procedure for the five-qubit code may be extended to work on the five qudit code for any prime ... -
Flags and Error Weight Parities: A Development of Fault-tolerant Quantum Computation with Few Ancillas
