The selfassembly of particles with isotropic interactions: Using DNA coated colloids to create designer nanomaterials
(AIP publishing, 20140403)Selfconsistent field theory equations are presented that are suitable for use as a coarsegrained model for DNA coated colloids, polymergrafted nanoparticles and other systems with approximately isotropic interactions. ... 
SemiAnalytic Radiatively Inefficient Accretion Flows in General Gravity
(University of Waterloo, 20180105)The Event Horizon Telescope is capable of observing black holes on eventhorizon scales and we can use it to explore deviations from General Relativity. We replicate the results of a previous study using a Newtonian ... 
Sensing the shape of spacetime: detector response and entanglement harvesting in curved space
(University of Waterloo, 20190124)This thesis seeks to understand what information UnruhDeWitt 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 ... 
A sensitive search for dark energy through chameleon scalar fields using neutron interferometry
(IOP Publishing, 20150122)The physical origin of the dark energy, which is postulated to cause the accelerated expansion rate of the universe, is one of the major open questions of cosmology. A large subset of theories postulate the existence of a ... 
Setup and Design of a Cryogenic Testing Station with Focus on Characterization of Superconducting Devices
(University of Waterloo, 20190523)The goal of my thesis was to construct a general purpose cryostat, capable of measuring multiple devices at 100mK. This included modifying an existing SHASTA model 106 Adiabatic Demagnetization Refrigerator (ADR) by adding ... 
Setup of Dry Cryostat for Measurements on Superconducting Microwave Resonators
(University of Waterloo, 20190920)A cryogenfree cryostat was set up in order to perform measurements at ultra low temperatures. The setup involved the removal of an adiabatic demagnetization refrigerator (ADR) and replacing it with a dilution refrigerator ... 
Shape dynamics and Mach's principles: Gravity from conformal geometrodynamics
(University of Waterloo, 20110826)We develop a new approach to classical gravity starting from Mach's principles and the idea that the local shape of spatial configurations is fundamental. This new theory, shape dynamics, is equivalent to general relativity ... 
The Shape of Dark Matter Haloes: Results from Weak Lensing
(University of Waterloo, 20200925)Dark matter haloes are expected to have a triaxial shape, appearing elliptical in projection. Understanding the orientation of these dark matter haloes, and how they are aligned, has implications for theories of structure ... 
Signatures of New Physics from the Primordial Universe
(University of Waterloo, 20070829)During inflation quantum fluctuations of the field driving inflation, known as inflaton, were stretched by inflationary expansion to galactic size scales or even larger. A possible implication of inflation  if it is ... 
Silicon avalanche photodiodes for satellite based quantum communication
(University of Waterloo, 20180925)Single photons detectors are required for applications like quantum key distribution and testing Bell's inequalities. Silicon avalanche photodiodes (Si APD's) have advantages like low dark count rate. This thesis aims to ... 
Simple and Accurate Calibration of the FloryHuggins Interaction Parameter
(University of Waterloo, 20210901)This work improves on a standard method used to calibrate χ, the FloryHuggins interaction parameter, in experimental systems. The common method is to fit the orderdisorder transition (ODT) of symmetric diblock copolymer ... 
Simulating ManyBody States of Light and Matter with Tensor Networks
(University of Waterloo, 20220929)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 ... 
Simulating quantum matter through lattice field theories
(University of Waterloo, 20170516)Quantum manybody systems are comprised of complex networks of microscopic interactions that work together to produce novel collective phases and phenomena. For stronglyinteracting systems, the connection between the ...
