Ultrafast Metrology in the Quantum Domain
(University of Waterloo, 2019-02-15)Single photons are a natural platform for quantum technologies as they support entanglement in many degrees of freedom and are inherently well protected from a detrimental type of noise called decoherence. In order to ... -
Techniques for Coherent Control of Effective Photon-Photon Interactions at Low Light Levels
(University of Waterloo, 2019-02-01)This thesis proposes improvements on techniques for the coherent control of photon-photon interactions mediated by a cloud of cold atoms. Atoms cooled and trapped in a MOT can be loaded into a hollow, photonic crystal ... -
Octupolar Ordering in the b>0 Bilinear-Biquadratic Heisenberg Pyrochlore
(University of Waterloo, 2019-01-25)We investigate the bilinear-biquadratic Heisenberg model on the pyrochlore lattice. While negative biquadratic couplings result in a first-order transition into a nematic ordered state with spins aligned mutually ... -
Sensing the shape of spacetime: detector response and entanglement harvesting in curved space
(University of Waterloo, 2019-01-24)This thesis seeks to understand what information Unruh-DeWitt detectors can gain about the structure of spacetime. By coupling to the quantum state of a field on a curved space, the detectors can gain information about ... -
Study of Surface Quantum Wells in InSb/AlInSb Heterostructures
(University of Waterloo, 2019-01-24)The strong spin orbit coupling and large Lande g-factor of InSb compared to the other III-V semiconductors makes InSb an ideal choice for potential use in topological quantum computing with Majorana fermions. Furthermore, ... -
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. ... -
Methods for parallel quantum circuit synthesis, fault-tolerant quantum RAM, and quantum state tomography
(University of Waterloo, 2019-01-18)The pace of innovation in quantum information science has recently exploded due to the hope that a quantum computer will be able to solve a multitude of problems that are intractable using classical hardware. Current quantum ... -
Probing Accretion Turbulence in the Galactic Centre with EHT Polarimetry
(University of Waterloo, 2019-01-09)We explore the origin and the influence of the interstellar scattering on the observation of Sgr A*, and the method to mitigate this scattering via Event Horizon Telescope (EHT) polarimetry. Interstellar scattering is due ... -
Dark Matter and Neutrinos in the Foggy Universe
(University of Waterloo, 2019-01-07)Dark matter is predicted to be the main contribution to the matter content in the universe, in addition to ordinary baryonic matter such as protons and neutrons. However, we are limited in our knowledge of the nature of ... -
Transition to light-like trajectories in thin shell dynamics
(Elsevier, 2018-11)It was recently shown that a massive thin shell that is sandwiched between a flat interior and an exterior geometry given by the outgoing Vaidya metric becomes null in a finite proper time. We investigate this transition ... -
Crystallization Studies of Highly Monodisperse Oligomeric Poly(Ethylene Oxide)
(University of Waterloo, 2018-12-13)Poly(ethylene oxide) is one of the most intensively studied polymers in terms of crystallization, because of its linear structure. In this thesis the chapters are organized in a self-contained fashion, with a general ... -
Augmenting Quantum Mechanics with Artificial Intelligence
(University of Waterloo, 2018-12-04)The simulation of quantum matter with classical hardware plays a central role in the discovery and development of quantum many-body systems, with far-reaching implications in condensed matter physics and quantum technologies. ... -
Topological Order and Universal Properties of Gapped Quantum Systems
(University of Waterloo, 2018-11-15)Phases of gapped quantum liquids are topologically ordered and have very interesting physical features that are completely robust against any local perturbation that do not close the bulk energy gap. These universal ... -
Synthesis of Polyynes by Femtosecond and Nanosecond Laser Interaction with Matter
(University of Waterloo, 2018-10-24)A review of literature including some history and previous work done in the field is done showing the importance of polyynes themselves and as an important precursor in the formation of other interesting carbon nanoparticles ... -
Rare Events Prediction: Rogue Waves and Drags
(University of Waterloo, 2018-10-24)Rogue waves are rare events with unusually large wave amplitudes. In this thesis the multicanonical procedure is applied to the one-dimensional nonlinear Schrödinger equation in conjunction with a high order finite difference ... -
New methods in quantum error correction and fault-tolerant quantum computing
(University of Waterloo, 2018-10-22)Quantum computers have the potential to solve several interesting problems in polynomial time for which no polynomial time classical algorithms have been found. However, one of the major challenges in building quantum ... -
Compact Two-color Ultrafast Yb:fiber Chirped Pulse Amplifiers and Mid-infrared Generation Based on Difference Frequency Generation

Polarimetric and birefringence analysis of presumed amyloid-beta deposits in the retina in association with Alzheimer's disease
(University of Waterloo, 2018-09-26)Alzheimer's disease is a neurodegenerative disease which leads to symptoms such as loss of memory and other neurological dysfunctions, ultimately leading to death. Two key hallmarks of Alzheimer's disease are abnormally ... -
An ALMA View of Molecular Gas in Brightest Cluster Galaxies
(University of Waterloo, 2018-09-25)In this thesis I use ALMA observations to map the distribution and kinematics of molecular gas in the brightest cluster galaxies of three galaxy clusters: 2A0335+096, RXJ0821+0752, and RXCJ1504-0248. The goal is to understand ... -
