Aspects of Quantum Field Theory with Boundary Conditions
(University of Waterloo, 2019-08-02)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 non-trivial boundary conditions (Dirichlet, Neumann, periodic; ... -
Aspects of Quantum Information and AdS/CFT Duality
(University of Waterloo, 2021-05-17)This thesis considers four different aspects of quantum information, AdS/CFT duality, and the interplay between them. First, we study the holographic complexity conjectures in detail for rotating black holes. We focus ... -
Aspects of Scattering Amplitudes and Moduli Space Localization
(University of Waterloo, 2019-08-19)We propose that intersection numbers of certain cohomology classes on the moduli space of genus-zero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute tree-level scattering amplitudes in quantum field ... -
Assessing the Accuracy of Cosmological Parameters Estimated from Velocity – Density Comparisons
(University of Waterloo, 2024-01-10)A promising method for measuring the cosmological parameter combination fσ₈ is to compare observed peculiar velocities with peculiar velocities predicted from a galaxy density field using linear perturbation theory, known ... -
Assessing the Practicality of a Simple Multi-node Quantum Repeater
(University of Waterloo, 2017-10-25)This thesis assesses the theoretical performance of a realistic multi-node 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, 2019-12-09)We perform a rigorous piecewise-flat discretization of classical general relativity in the first-order 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, 2012-09-26)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 ... -
Atomic shell structure from an orbital-free-related density-functional-theory Pauli potential
