Twisted Holography: The Examples of 4d and 5d Chern-Simons Theories
(University of Waterloo, 2022-09-29)Twisted holography is a duality between a twisted supergravity, and a twisted supersymmetric gauge theory living on the D-branes in the supergravity. The main objectives of this duality is the comparison between the algebra ... -
Simulating Many-Body States of Light and Matter with Tensor Networks
(University of Waterloo, 2022-09-29)When Feynman originally proposed the concept of a quantum computer, his purpose was to perform quantum simulation of complex materials. It is thus a key requirement that quantum resources can emulate physical processes ... -
Hodge Theory for Geometrically Frustrated Magnetism
(University of Waterloo, 2022-09-29)We present an analytical formalism based on the concept of discrete differential forms and Hodge theory as a framework for understanding geometrically frustrated magnetism. The primary insight is to treat spins as a 1-form ... -
Beyond General Relativity: New Structure and Stability Predictions from Modified Gravity and High-Density Interaction Models
(University of Waterloo, 2022-09-29)In this thesis a number of topics are explored in an attempt to further understand gravitation and highly dense matter on a fundamental level. The notion of “quark stars” (QS), hypothetical compact stars composed of quark ... -
Collective Spin-Cavity Ensembles and the Protection of Higher-dimensional Quantum Information
(University of Waterloo, 2022-09-28)The development of devices leveraging their quantum nature to outperform classical analogues has been an ongoing effort for many decades now. In this thesis we investigate two facets related to this effort, albeit at ... -
Powell Lens-based Line-Scan Spectral Domain Optical Coherence Tomography for Cellular Resolution Imaging of Biological Tissues
(University of Waterloo, 2022-09-28)A line-scan spectral-domain optical coherence tomography system was developed for corneal imaging. It utilizes a Powell lens to achieve a better line illumination power distribution than the conventional use of cylindrical ... -
Edge Modes and Carrollian Hydrodynamics on Stretched Horizons
(University of Waterloo, 2022-09-27)The first part of this thesis is aimed at investigating the crucial role played by emergent boundary degrees of freedom, called edge modes, in gauge theories defined in spacetimes with boundaries. We propose a simple and ... -
Studying Black Holes in Superposition Using Unruh-DeWitt Particle Detectors
(University of Waterloo, 2022-09-27)In quantum gravity, we expect black holes to exist in quantum superposition. However, the measurable effects of black hole superpositions have not been studied widely. In this thesis, we study superpositions of different ... -
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 ... -
Investigating future galaxy surveys of cosmological large-scale structure
(University of Waterloo, 2022-09-26)My thesis consists of the two following projects: 1-Testing Large-Scale Structure Measurements against Fisher Matrix Analysis (Chapter 2): We compare Baryonic Acoustic Oscillation (BAO) and Redshift Space Distortion ... -
Improved Keyrates for Quantum Key Distribution from two-way Classical Communication
(University of Waterloo, 2022-09-22)Quantum Key Distribution (QKD) promises information-theoretic security of secret keys. An important metric for QKD protocols is the asymptotic keyrate. We propose and analyze several new classical processing protocols for ... -
