      Bednik, Grigory (University of Waterloo, 2018-08-30)
      In this work we explore superconductivity and surface states in topological semimetals. We start from general overview of basic properties of topological semimetals. We review general concepts of Chern insulators, their ...

      Hickey, Alexander (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. ...
    • Topological Manipulations of Quantum Field Theories 

      Kulp, Justin (University of Waterloo, 2023-07-17)
      In this thesis we study some topological aspects of Quantum Field Theories (QFTs). In particular, we study the way in which an arbitrary QFT can be separated into “local” and “global” data by means of a “symmetry Topological ...
    • Topological methods in quantum gravity 

      Starodubtsev, Artem (University of Waterloo, 2005)
      The main technical problem with background independent approaches to quantum gravity is inapplicability of standard quantum field theory methods. New methods are needed which would be adapted to the basic principles ...
    • Topological Order and Universal Properties of Gapped Quantum Systems 

      Moradi, Heidar (University of Waterloo, 2018-11-15)
      Phases of gapped quantum liquids are topologically ordered and have very interesting physical features that are completely robust against any local perturbation that do not close the bulk energy gap. These universal ...
    • Topological Order in String Liquids and Weyl Semimetals 

      Sehayek, Dan (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 

      Hook, Michael (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 

      Panfilov, Ivan (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 ...
