    • The black hole information paradox in a brane world 

      Chen, Hong Zhe (University of Waterloo, 2023-06-28)
      Recent progress in our understanding of the black hole information paradox has led to a new prescription for calculating entanglement entropy, which involves special subsystems in regions where gravity is dynamical, called ...
    • Black Hole Thermodynamics and the Tunnelling Method for Particle Emission 

      Kerner, Ryan (University of Waterloo, 2008-08-29)
      The semi-classical black hole tunnelling method is a useful technique to calculate black hole temperature and understand black hole thermodynamics. I will investigate the black hole tunnelling method in detail. I will ...
    • Black holes in cosmological spacetimes and alternative theories of gravity

      Robinson, Brandon (University of Waterloo, 2009-08-05)
      In the following, we build on previous work done on higher derivative gravity, in particular Lovelock gravity. The latter is a family of theories in higher space-time dimensions in which interactions involving higher ...
    • Block Copolymer-Directed Assembly of Nanoparticles: Forming Mesoscopically Ordered Hybrid Materials 

      Thompson, Russell B.; Ginzburg, Valeriy V.; Matsen, Mark W.; Balazs, Anna C. (American Chemical Society, 2002)
      Mixtures of diblock copolymers and nanoscopic spherical particles can yield well-ordered hybrid materials, which can be used for separation processes, catalysis, and optoelectronic applications. Predicting the morphologies ...
    • Bohmian Mechanics: Towards Illuminating The Quantum Potential 

      Brown, Matthew (University of Waterloo, 2018-02-20)
      This thesis deals with the theoretical and experimental details of trying to understand and infer the quantum potential from Bohmian mechanics using Bohmian trajectories. In this work, some of the key components of the ...
    • Bootstrapping Quantum Field Theories 

      Homrich, Alexandre (University of Waterloo, 2024-01-23)

    • 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 ...
    • Born Reciprocal Representations of the Quantum Algebra 

      Yargic, Yigit (University of Waterloo, 2021-08-26)
      This thesis addresses the representations of the Weyl algebra of quantum mechanics with an explicitly Born reciprocal structure and the dynamics of physical systems in these representations. In this context, we discuss ...
    • Bosonic fields in strong-field gravity 

      Siemonsen, Nils (University of Waterloo, 2023-07-19)
      In this thesis, we investigate bosonic fields in the strong-field and highly dynamical regime of general relativity focusing specifically on the black hole superradiance process of scalar and vector fields, as well as on ...

      Willis, James; Beardsley, Tom; Matsen, Mark (AIP, 2019-05-06)
      The Morse calibration is applied to a lattice model designed for efficient simulations of two-component polymer melts of high molecular weight. The model allows multiple occupancy per site, which results in high invariant ...
    • Can Lensing Measure The Shape Of Dark Matter Halos? 

      Hussain, Uzair (University of Waterloo, 2012-09-27)
      The aim of this project was to explore the shapes of dark matter halos using high resolution N-body simulations. One of the main aspects explored was how well the shape can be measured through weak lensing. To explore this, ...
