An investigation of low energy quasiparticle excitations via thermal transport measurements
(University of Waterloo, 2017-06-16)Thermal transport measurements can provide a unique perspective of the nature of a system by exploring the behaviour of the low energy excitations from the ground state. Delocalized quasiparticle excitations can affect ... -
Quantum critical responses via holographic models and conformal perturbation theory
(University of Waterloo, 2017-06-15)We investigate response functions near quantum critical points, allowing for finite temperature and a mild deformation by a relevant scalar. When the quantum critical point is described by a conformal field theory, we use ... -
Quantum Information Enabled Neutron Interferometry
(University of Waterloo, 2017-06-12)Neutron interferometry with its ability to encode and extract information provides a test bed for quantum mechanics and precise measurement of physical quantities of significant importance in physics. However, this ... -
Quantum Gates and Decoupling in Qubits with Fixed Transverse Coupling
(University of Waterloo, 2017-05-25)Among all the quantum computer candidates, the superconducting system is one of the most convincing platforms due to its strong couplings and scalability. To be more specific, this thesis focuses on the superconducting ... -
Simulating quantum matter through lattice field theories
(University of Waterloo, 2017-05-16)Quantum many-body systems are comprised of complex networks of microscopic interactions that work together to produce novel collective phases and phenomena. For strongly-interacting systems, the connection between the ... -
Topology and interactions in Weyl metals and quantum Hall systems
(University of Waterloo, 2017-05-10)In recent years it became clear that in the Condensed Matter physics, the study of the interactions and the topology allows one to find and to describe many new phases of matter. Even more interest was drawn by the ... -
Horizon Thermodynamics from Einstein's Equation of State
(University of Waterloo, 2017-04-28)The striking resemblance between geometric theories of gravity and thermodynamics suggests a more fundamental relationship between the two seemingly distinct theories. It has been postulated that the radial Einstein ... -
The Dependence of Halo Mass on Galaxy Size at Fixed Stellar Mass Using Weak Lensing
(University of Waterloo, 2017-04-24)Stellar mass has been shown to correlate with halo mass, but with significant scatter. The stellar mass-size and luminosity-size relationships of galaxies also show significant scatter in galaxy sizes for a fixed stellar ... -
A Novel Combination Therapy of Cisplatin with a Molecular Promoter for Cancer Treatment
(University of Waterloo, 2017-01-25)Cisplatin is the first and most widely used platinum-based chemotherapy drug and is the cornerstone agent in treating a broad spectrum of cancers, including ovarian cancer, testicular cancer, cervical cancer, bladder cancer, ... -
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 ... -
On The Origin of Cold Molecular Gas In Giant Elliptical Galaxies
(University of Waterloo, 2017-01-23)We present an analysis of 55 giant elliptical galaxies residing in the centre of clusters and groups to investigate the origin of H₂ molecular gas centrally located in these galaxies. Using Chandra X-ray data and IRAM 30m ... -
RF-QPC Charge Detector and S-T₊ Qubit in a Lateral Double Quantum Dot Device
(University of Waterloo, 2017-01-18)A measurement system is developed for studying a lateral double quantum dot (DQD) device formed in the two-dimensional electron gas (2DEG) of a GaAs/AlGaAs heterostructure. Copper powder and RC filters are constructed to ... -
Topics in Fault-Tolerant Quantum Computation
(University of Waterloo, 2017-01-12)This thesis contains the results of research projects broadly related to the pursuit of universal fault-tolerant quantum computation. We are interested in questions such as which resources are required to achieve a quantum ... -
Electron transport in semiconducting nanowires and quantum dots
(University of Waterloo, 2017-01-10)Single electrons confined in electrostatic quantum dots are a promising platform for realizing spin based quantum information processing. In this scheme, the spin of each electron is encoded as a qubit, and can be manipulated ... -
Conical Designs and Categorical Jordan Algebraic Post-Quantum Theories
(University of Waterloo, 2017-01-06)Physical theories can be characterized in terms of their state spaces and their evolutive equations. The kinematical structure and the dynamical structure of finite dimensional quantum theory are, in light of the ... -
Ultrafast manipulation of single photons using dispersion and sum-frequency generation
(University of Waterloo, 2016-12-01)Single photons provide a natural platform for quantum communication and quantum networking, as they can be entangled in many degrees of freedom and maintain coherence over long-distance links. However, while their minimal ... -
Collective Dynamics in NMR and Quantum Noise
(University of Waterloo, 2016-10-17)We introduced an open quantum system model to describe the statistical fluctuations of a spin ensemble in NMR. The model considers an ensemble measurement where the detection coil does not distinguish spins, and accounts ... -
Symmetric Extendability of Quantum States and the Extreme Limits of Quantum Key Distribution
(University of Waterloo, 2016-10-13)We investigate QKD protocols with two-way classical post-processing that are based on the well-known six-state and BB84 signal states. In these QKD protocols, the source (Alice) sends quantum signals to the receiver (Bob), ... -
The computational power of many-body systems
(University of Waterloo, 2016-09-28)Many-body systems are well known throughout physics to be hard problems to exactly solve, but much of this is folklore resulting from the lack of an analytic solution to these systems. This thesis attempts to classify the ... -
In vitro test of a potential hypoxic radiosensitizer
(University of Waterloo, 2016-09-28)Oxygen has long been known as a potent radiosensitizer that can enhance the cell killing effects in aerobic cells, while pruned vasculatures and lack of oxygen in the microenvironment of tumor can cause resistance to ...
