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, ... 
Canonical Structure and Conservation Laws of General Relativity on Null Surfaces and at Null Infinity
(University of Waterloo, 20210112)The first part of this thesis addresses the canonical structure of general relativity on generic null surfaces. The presymplectic potential of metric general relativity, evaluated on a null surface, is decomposed into ... 
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 ... 
Cats, Rotating Waves and Photons: An Excursion into LightMatter Interaction
(University of Waterloo, 20230927)This thesis hopes to achieve two modest goals. The primary goal is to formulate a practical theory for generating cat states by employing a resonant or detuned strong drive on a qubit coupled to a resonator. An incidental ... 
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 ... 
Chaos and dynamical instability in a closed kicked system
(University of Waterloo, 20230808)Quantumclassical correspondence plays an important role in understanding the emergence of classical chaos from underlying quantum mechanics. However, the transition from quantum to classical is not straightforward. Here ... 
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 ...
