Topological Order in String Liquids and Weyl Semimetals
(University of Waterloo, 2022-08-22)Outside Landau's paradigm of symmetry-breaking orders is the class of topological orders, which cannot be described by a local order parameters. Such orders are generally defined by the presence of a gauge symmetry and ... -
Topological Semimetals
(University of Waterloo, 2012-08-31)This thesis describes two topological phases of matter, the Weyl semimetal and the line node semimetal, that are related to but distinct from topological insulator phases. These new topological phases are semimetallic, ... -
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 ... -
Topology in Fundamental Physics
(University of Waterloo, 2011-09-02)In this thesis I present a mathematical tool for understanding the spin networks that arise from the study of the loop states of quantum gravity. The spin networks that arise in quantum gravity possess more information ... -
Total Retinal Blood Flow and Retinal Oxygen Saturation in the Major Retinal Vessels of Healthy Participants
(University of Waterloo, 2013-09-27)Introduction: Oxygen delivery, or utilization, is a function of retinal blood flow and blood oxygen saturation. The retinal pigment epithelium (RPE), in particular, has been shown to have the highest levels of metabolic ... -
Toward a theory of everything
(University of Waterloo, 2023-08-21)A physical theory of everything is supposed to tell us: (1) The dynamical laws for matter and gravity; (2) The boundary condition of the universe; (3) The relation between the theory and experience. I present a personal ... -
Toward Canonical General Relativity in the Loop Gravity Phase Space
(University of Waterloo, 2014-01-07)The continuous, kinematical Hilbert space of loop quantum gravity is built upon a family of spaces $\mathcal{H}_\Gamma$, each associated to a different \textit{graph} $\Gamma$, i.e. a network of interconnected one-dimensional ... -
Toward Fast and Quantitative Modification of Large Gold Nanoparticles by Thiolated DNA: Scaling of Nanoscale Forces, Kinetics, and the Need for Thiol Reduction
(American Chemical Society, 2013-08-01)We have recently reported on the fast and quantitative adsorption of DNA to 13 nm gold nanoparticles (AuNPs) at pH 3. This is in contrast to most traditional methods at neutral pH, where the adsorption is both slow and ... -
Toward standardization of Quantum Key Distribution
(University of Waterloo, 2020-09-03)Information security becomes an inseparable part of our everyday life. An encryption method widely used today is public-key encryption. The security of this method is based on a hard to solve mathematical problems against ... -
Toward Ultracold Atoms for Quantum Thermalization Studies
(University of Waterloo, 2023-01-02)Ultracold atoms are a great platform to understand one of the most interesting open problems in physics: quantum thermalization. Building a new lab for ultracold atoms is a challenging task for the various tools that ... -
Towards a Better Understanding of the Na-O2 Battery System
(University of Waterloo, 2016-09-28)The electrification of transportation requires cost-effective energy storage systems with high energy densities. Aprotic sodium-oxygen batteries offer great promise for advanced energy storage as these batteries possess ... -
