The black hole information paradox in a brane world
(University of Waterloo, 2023-06-28)Recent progress in our understanding of the black hole information paradox has led to a new prescription for calculating entanglement entropy, which involves special subsystems in regions where gravity is dynamical, called ... -
Black Hole Thermodynamics and the Tunnelling Method for Particle Emission
(University of Waterloo, 2008-08-29)The semi-classical 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 cosmological spacetimes and alternative theories of gravity
(University of Waterloo, 2023-08-09)This thesis is dedicated to the study of spacetimes surrounding black holes within the context of cosmology, high energy physics and modified theories of gravity. We do this by applying and adapting modern numerical ... -
Black Holes in Pseudo-Topological Gravity
(University of Waterloo, 2009-08-05)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 space-time dimensions in which interactions involving higher ... -
Block Copolymer-Directed Assembly of Nanoparticles: Forming Mesoscopically Ordered Hybrid Materials
(American Chemical Society, 2002)Mixtures of diblock copolymers and nanoscopic spherical particles can yield well-ordered hybrid materials, which can be used for separation processes, catalysis, and optoelectronic applications. Predicting the morphologies ... -
Bohmian Mechanics: Towards Illuminating The Quantum Potential
(University of Waterloo, 2018-02-20)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 ... -
Bootstrapping Quantum Field Theories
(University of Waterloo, 2024-01-23)This thesis compiles a few developments on the S-matrix bootstrap, conformal field theory, and integrability in N = 4 SYM. After an introduction contextualizing the various works that compose this thesis, we present a ... -
Born Geometry
(University of Waterloo, 2020-04-21)In this thesis, we summarize the work which we authored or co-authored during our PhD studies and also present additional details and ideas that are not found elsewhere. The main topic is the study of T-duality in theoretical ... -
Born Reciprocal Representations of the Quantum Algebra
(University of Waterloo, 2021-08-26)This thesis addresses the representations of the Weyl algebra of quantum mechanics with an explicitly Born reciprocal structure and the dynamics of physical systems in these representations. In this context, we discuss ... -
Bosonic fields in strong-field gravity
(University of Waterloo, 2023-07-19)In this thesis, we investigate bosonic fields in the strong-field and highly dynamical regime of general relativity focusing specifically on the black hole superradiance process of scalar and vector fields, as well as on ... -
Calibration of a Lattice Model for High-Molecular-Weight Block Copolymer Melts
(AIP, 2019-05-06)The Morse calibration is applied to a lattice model designed for efficient simulations of two-component 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, 2012-09-27)The aim of this project was to explore the shapes of dark matter halos using high resolution N-body 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, 2021-01-12)The first part of this thesis addresses the canonical structure of general relativity on generic null surfaces. The pre-symplectic potential of metric general relativity, evaluated on a null surface, is decomposed into ... -
Carbon nanotube electromechanical systems: Non-linear dynamics and self-oscillation
(University of Waterloo, 2020-05-13)This thesis is motivated by the many sensing applications of carbon nanotube (CNT) nano-electromechanical systems (NEMS), both previous state-of-the-art demonstrations and proposed new uses. This research is particularly ... -
Cats, Rotating Waves and Photons: An Excursion into Light-Matter Interaction
(University of Waterloo, 2023-09-27)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, 2020-01-13)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, 2016-05-18)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, 2023-08-08)Quantum-classical 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 ... -
