An Exploration of Clustering Statistics and Tidal Alignments in the Context of Group Catalogues
(University of Waterloo, 2021-10-04)The use of three-dimensional galaxy surveys and large cosmological simulations of the galaxy distribution has advanced our understanding of large-scale structure over the last few decades. At the forefront of this are ... -
Exploration of Higher-Order Quantum Interference Landscapes
(University of Waterloo, 2017-08-31)Earth, Moon and Sun unite when they star together in the three-body problem, whose intricate plot still baffles us today. For some reason, the factorization of the two-body problem into two one-body problems does not, in ... -
An Exploration of Locality, Conservation Laws, and Spin
(University of Waterloo, 2017-01-23)Conservation rules are central to our understanding of the physical world, they place re- strictions on how particles can move and dictate what can occur during an interaction. However, it is often taken for granted how a ... -
An Exploration of Secure Circular Multi-Party Quantum Computation
(University of Waterloo, 2022-09-26)Multi party quantum computation (MPQC) is any quantum cryptographic protocol where multiple untrusted users collaborate to perform calculations on their combined data without revealing their private information. MPQC is ... -
Explorations in black hole chemistry and higher curvature gravity
(University of Waterloo, 2018-08-08)This thesis has two goals. The primary goal is to communicate two results within the framework of black hole chemistry, while the secondary goal is concerned with higher curvature theories of gravity. Super-entropic ... -
Explorations in machine learning for interacting many-body systems.
(University of Waterloo, 2020-09-03)Most interacting many-body systems in physics are not analytically solvable. Instead, numerical methods are needed for the study of these complex and high-dimensional problems. At present, there are many interesting problems ... -
Explorations in the Conformal Bootstrap
(University of Waterloo, 2017-07-19)We investigate properties of various conformally invariant quantum systems, especially from the point of view of the conformal bootstrap. First, we study twist line defects in three-dimensional conformal field theories. ... -
Explorations of Black Hole Thermodynamics in de Sitter Spacetime
(University of Waterloo, 2019-01-23)In this thesis I map out two approaches that are foundational to studying black hole thermodynamics in de Sitter spacetime. The first is to understand the "thermodynamic volume" of cosmological horizons in isolation. ... -
Exploring many-body Physics with Recurrent Neural Networks
(University of Waterloo, 2023-06-22)Originally developed within the natural language processing community, Recurrent neural networks (RNNs) have enabled remarkable progress in speech recognition and machine translation. These architectures belong to the class ... -
Exploring new routes to decoherence-free quantum computing; and quantum thermodynamics for fermions
(University of Waterloo, 2020-01-23)This thesis has two parts; the first part is a contribution to the research field of quantum measurement in quantum optics while the second part focuses on quantum thermodynamics for fermionic systems. The aim of the ... -
Exploring the foundation of quantum information in quantum optics
(University of Waterloo, 2016-09-21)Quantum information is promising in solving certain computational problems and information security. The power of its speed up and privacy is based on one of the most tested physical theory: quantum mechanics. Many of ... -
Extended thermodynamics of Taub-NUT and Einstein-scalar spacetimes
(University of Waterloo, 2021-08-12)The main objective of this thesis is to summarize recent developments on the thermodynamics of both AdS Einstein-scalar spacetimes and Lorentzian Taub-NUT spacetimes. We summarize and apply well-known techniques in black ... -
Fabrication of an Atom Chip for Rydberg Atom-Metal Surface Interaction Studies
(University of Waterloo, 2007-09-28)This thesis outlines the fabrication of two atom chips for the study of interactions between ⁸⁷Rb Rydberg atoms and a Au surface. Atom chips yield tightly confined, cold samples of an atomic species by generating magnetic ... -
Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging
(American Physical Society, 2017-04-26)The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The ... -
Fast control and decoherence in superconducting quantum circuits
