Characterization of Detector and Electron Source for Inverse Photoemission Spectrometer
(University of Waterloo, 2023-02-17)The inverse photo-emission spectroscopy (IPES) is a powerful tool to probe the unoccupied energy states of materials, such the surface states of metals or the unoccupied states of high temperature superconductors. IPES ... -
Computational Methods for the Measurement of Entanglement in Condensed Matter Systems
(University of Waterloo, 2014-06-19)At the interface of quantum information and condensed matter physics, the study of entanglement in quantum many-body systems requires a new toolset which combines concepts from each. This thesis introduces a set of ... -
Explorations in machine learning for interacting many-body systems.
(University of Waterloo, 2020-09-03)Most interacting many-body systems in physics are not analytically solvable. Instead, numerical methods are needed for the study of these complex and high-dimensional problems. At present, there are many interesting problems ... -
Holographic Experiments on Defects
(University of Waterloo, 2009-09-03)Using the AdS/CFT correspondence, we study the anisotropic transport properties of both supersymmetric and non-supersymmetric matter fields on (2+1)-dimensional defects coupled to a (3+1)-dimensional N=4 SYM "heat bath". ... -
Interactions, Entanglement, and Anomalies in Topological Semimetals
(University of Waterloo, 2023-08-04)Topology and symmetry have become one of the backbones of modern condensed matter physics. These concepts play a large role in determining the possible effects of interactions and entanglement in both gapped and gapless ... -
Machine Learning Topological Defects of Liquid Crystals in Two Dimensions
(University of Waterloo, 2019-08-26)Over the recent few years, condensed matter physics has keenly been testing out the compelling techniques from the toolbox of machine learning. Order parameters, phase transitions, and other thermodynamic quantities have ... -
Probing universality with entanglement entropy via quantum Monte Carlo
(University of Waterloo, 2019-08-30)Our understanding of physical phenomena hinges on finding universal core mechanisms that unite them. The concept of universality is deeply ingrained in the study of quantum many-body systems. At zero temperature, microscopically ... -
A Study of Order-by-Disorder Phenomenon in Frustrated Magnetic Systems Near Criticality
(University of Waterloo, 2014-04-25)Order-by-disorder is the phenomenon of the selection of a long-ranged ordered state by fluctuations in a many-body system. This mechanism, at first sight, seems paradoxical, since fluctuations (disorder) intuitively tend ... -
Thickness- and Symmetry-Induced Electronic Transport Properties of Semimetallic Transition Metal Dichalcogenides
(University of Waterloo, 2023-01-12)This thesis presents experimental study of how thickness and symmetry would impact the electron transport properties of MoTe₂ and WTe₂, two members of the transition metal dichalcogenide family. In the first experiment, ... -
Topological aspects of nodal-loop semimetals and the nature of spin-orbit coupling in Lu₂V₂O₇
(University of Waterloo, 2021-09-27)This thesis is presented in two parts: (I) understanding the topological aspects of nodal-loop semimetals in the presence of interactions and (II) exploring the nature of spin-orbit coupling in the pyrochlore oxide Lu₂V₂O₇. ...
