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; ... 
Aspects of Scattering Amplitudes and Moduli Space Localization
(University of Waterloo, 20190819)We propose that intersection numbers of certain cohomology classes on the moduli space of genuszero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute treelevel scattering amplitudes in quantum field ... 
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 ... 
At the Corner of Space and Time
(University of Waterloo, 20191209)We perform a rigorous piecewiseflat discretization of classical general relativity in the firstorder formulation, in both 2+1 and 3+1 dimensions, carefully keeping track of curvature and torsion via holonomies. We show ... 
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 ... 
Augmenting Quantum Mechanics with Artificial Intelligence
(University of Waterloo, 20181204)The simulation of quantum matter with classical hardware plays a central role in the discovery and development of quantum manybody systems, with farreaching implications in condensed matter physics and quantum technologies. ... 
Benchmarking a selfconsistent field theory for small amphiphilic molecules
(RSC publishing, 20120814)A minimalist selfconsistent field theory for small amphiphilic molecules is presented. The equations for this model are less involved than those for block copolymers and are easily implemented computationally. A new ... 
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 ... 
Bidirectional mapping between selfconsistent field theory and molecular dynamics
(AIP Publishing, 20071008)A bidirectional mapping scheme that bridges particlebased and fieldbased descriptions for polymers is presented. Initial application is made to immiscible homopolymer blends. The forward mapping (upscaling) approach ... 
Biophysical Modelling of Antimicrobial Peptide’s Interactions with Phospholipid and Lipopolysaccharide Membranes
(University of Waterloo, 20190523)Antimicrobial peptides (AMPs) are naturallyoccurring peptide antibiotics. The way they work has inspired a vigorous search for optimized peptide antibiotics for fighting resistant bacteria. Cationic AMPs cleverly utilize ... 
Black Hole Thermodynamics and the Tunnelling Method for Particle Emission
(University of Waterloo, 20080829)The semiclassical black hole tunnelling method is a useful technique to calculate black hole temperature and understand black hole thermodynamics. I will investigate the black hole tunnelling method in detail. I will ... 
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 ... 
Bohmian Mechanics: Towards Illuminating The Quantum Potential
(University of Waterloo, 20180220)This thesis deals with the theoretical and experimental details of trying to understand and infer the quantum potential from Bohmian mechanics using Bohmian trajectories. In this work, some of the key components of the ... 
Born Geometry
(University of Waterloo, 20200421)In this thesis, we summarize the work which we authored or coauthored during our PhD studies and also present additional details and ideas that are not found elsewhere. The main topic is the study of Tduality in theoretical ... 
Calibration of a Lattice Model for HighMolecularWeight Block Copolymer Melts
(AIP, 20190506)The Morse calibration is applied to a lattice model designed for efficient simulations of twocomponent polymer melts of high molecular weight. The model allows multiple occupancy per site, which results in high invariant ... 
Can Lensing Measure The Shape Of Dark Matter Halos?
(University of Waterloo, 20120927)The aim of this project was to explore the shapes of dark matter halos using high resolution Nbody simulations. One of the main aspects explored was how well the shape can be measured through weak lensing. To explore this, ... 
Carbon nanotube electromechanical systems: Nonlinear dynamics and selfoscillation
(University of Waterloo, 20200513)This thesis is motivated by the many sensing applications of carbon nanotube (CNT) nanoelectromechanical systems (NEMS), both previous stateoftheart demonstrations and proposed new uses. This research is particularly ... 
Causal Discovery of Photonic Bell Experiments
(University of Waterloo, 20200113)A causal understanding of a physical theory is vital. They provide profound insights into the implications of the theory and contain the information required to manipulate, not only predict, our surroundings. Unfortunately, ... 
Causal Models for a Quantum World
(University of Waterloo, 20160518)Quantum mechanics has achieved unparalleled success as an operational theory, describing a wide range of experiments to remarkable accuracy. However, the physical foundations on which it rests remain as puzzling as they ... 
Characterisation and Optimization of Ultrashort Laser Pulses
(University of Waterloo, 2003)The ultrafast optical regime is defined, as it applies to laser pulses, along with a brief introduction to pulse generation and characterisation technologies. A more extensive description of our particular amplified ...
