On Cohomological Algebras in Supersymmetric Quantum Field Theories
(University of Waterloo, 20190816)In this thesis we compute certain supersymmetric subsectors of the algebra of observables in some QFTs and demonstrate an application of such computation in checking an instance of Holographic duality. Computing the algebra ... 
Complexity in the AdS/CFT correspondence
(University of Waterloo, 20190814)The main goal of this thesis is to carefully analyze aspects of the gravitational quantities conjectured to be dual to quantum complexity in the AdS/CFT correspondence. The two most promising candidates for such holographic ... 
Constructing Exact Correlators In N=4 SYM Using Integrability
(University of Waterloo, 20190809)This thesis is devoted to the study of correlation functions in N = 4 superconformal Yang Mills theory. We focus on a class of four point functions for which we achieve formal results at finite coupling and explicit ... 
QuantumClassical Correspondence and Entanglement in Periodically Driven Spin Systems
(University of Waterloo, 20190809)This dissertation sets out to examine some fundamental open questions in quantum physics regarding quantumclassical correspondence in regular versus chaotic systems. Specifically, we study these questions using approaches ... 
Understanding sequential measurements in psiepistemic ontological models
(University of Waterloo, 20190806)Since the famous debates of Einstein & Bohr, physicists have argued about the nature of the quantum state. Is it best thought of as describing thewaythingsare out there in the world, or merely as a description of our ... 
Aspects of Quantum Field Theory with Boundary Conditions
(University of Waterloo, 20190802)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 nontrivial boundary conditions (Dirichlet, Neumann, periodic; ... 
The PROSPECT reactor antineutrino experiment
(Elsevier, 20190401)The Precision Reactor Oscillation and Spectrum Experiment, PROSPECT, is designed to make both a precise measurement of the antineutrino spectrum from a highlyenriched uranium reactor and to probe eVscale sterile neutrinos ... 
Engineering Effective Hamiltonians for Magnetic Resonance
(University of Waterloo, 20190722)Effective Hamiltonian engineering is a powerful technique that utilises timedependent perturbation theory to suppress or enhance certain effects that arise from otherwise weak Hamiltonian terms, when an experimenter ... 
The Vertex Algebra Vertex
(University of Waterloo, 20190719)This thesis reviews some aspects of a large class of vertex operator algebras labelled by $(p,q)$ webs colored by nonnegative integers associated to faces of the web diagrams [1,2,3,4]. Such vertex operator algebras ... 
Control techniques in spin based quantum computation
(University of Waterloo, 20190711)Working on quantum systems entail different interests, for example, working on fundamental understanding of quantum systems also lay foundation for better quantum computation techniques. A test for whether a system is ... 
Violation of an augmented set of LeggettGarg inequalities and the implementation of a continuous in time velocity measurement
(University of Waterloo, 20190711)Macroscopic realism (MR) is the view that a system may possess definite properties at any time independent of past or future measurements, and may be tested experimentally using the LeggettGarg inequalities (LGIs). In ... 
Few Hole Quantum Dots in a Gated GaAs/AlGaAs Heterostructure
(University of Waterloo, 20190624)This thesis presents a set of experiments that explore gate de ned hole quantum dots in the GaAs/AlGaAs heterostructure. These experiments explore the evolution of the quantum states of holes in a double quantum dot. The ... 
Customized nonlinearity shaping in imperfect or variable waveguides
(University of Waterloo, 20190531)Generation of highquality single photons via heralded parametric downconversion re quires careful design of spectral correlations in downconverted photon pairs. One step in this design process involves customized ... 
Characterizing Single Photon Emission From Quantum Dots in Nanowires
(University of Waterloo, 20190528)Bright sources of highly indistinguishable single photons are desirable for diverse applications in quantum technology, including quantum cryptographic protocols, information processing, and metrology. The most common ... 
Measuring NonMarkovianity of Noise in the Cenrtal Spin System
(University of Waterloo, 20190524)In this thesis, we explore nonMarkovian noise in the central spin system due to the coupling between the central spin and the environment. We use a solid state nuclear magnetic resonance system to do the experiment since ... 
Biophysical Modelling of Antimicrobial Peptide’s Interactions with Phospholipid and Lipopolysaccharide Membranes
(University of Waterloo, 20190523)Antimicrobial peptides (AMPs) are naturallyoccurring peptide antibiotics. The way they work has inspired a vigorous search for optimized peptide antibiotics for fighting resistant bacteria. Cationic AMPs cleverly utilize ... 
Symmetry of the Charge Ordering Phases in HoleDoped Cuprates Studied by Resonant XRay Absorption and Scattering
(University of Waterloo, 20190523)In the underdoped cuprates, superconductivity coexists with a rich variety of other electronic orders. Understanding the nature of these orders, how they interact with one another, and the mechanisms that produce them is ...
