    • Amplitudes in the Spin Foam Approach to Quantum Gravity 

      Chen, Linqing (University of Waterloo, 2017-07-31)
      In this thesis, we study a Spin Foam model for 4D Riemannian quantum gravity, and propose a new way of imposing the simplicity constraints that uses the recently developed holomorphic representation. Rather than imposing ...
    • At the Corner of Space and Time 

      Shoshany, Barak (University of Waterloo, 2019-12-09)
      We perform a rigorous piecewise-flat discretization of classical general relativity in the first-order formulation, in both 2+1 and 3+1 dimensions, carefully keeping track of curvature and torsion via holonomies. We show ...
    • Born Geometry 

      Svoboda, David (University of Waterloo, 2020-04-21)
      In this thesis, we summarize the work which we authored or co-authored during our PhD studies and also present additional details and ideas that are not found elsewhere. The main topic is the study of T-duality in theoretical ...
    • Edge Modes and Carrollian Hydrodynamics on Stretched Horizons 

      Jai-akson, Puttarak (University of Waterloo, 2022-09-27)
      The first part of this thesis is aimed at investigating the crucial role played by emergent boundary degrees of freedom, called edge modes, in gauge theories defined in spacetimes with boundaries. We propose a simple and ...
    • An Exploration of Locality, Conservation Laws, and Spin 

      Rempel, Trevor (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 ...
    • Gravitational Thermodynamics: From Black Holes to Holography 

      Simovic, Fil (University of Waterloo, 2021-06-01)
      The subject of gravitational thermodynamics lies at the center of numerous fields of study, many of which may seem disconnected, yet have proven to be deeply entwined. This thesis examines two primary facets of this subject, ...
    • Towards vertex renormalization in 4d Spin Foams 

      Banburski, Andrzej (University of Waterloo, 2017-07-24)
      A long-standing open problem in 4-dimensional Spin Foam models of Quantum Gravity has been the behavior of the amplitudes under coarse graining. In this thesis, we attempt to study this question by using the recent ...
