    • Aspects of Quantum Information and AdS/CFT Duality 

      Al Balushi, Abdulrahim (University of Waterloo, 2021-05-17)
      This thesis considers four different aspects of quantum information, AdS/CFT duality, and the interplay between them. First, we study the holographic complexity conjectures in detail for rotating black holes. We focus ...
    • Aspects of Scattering Amplitudes and Moduli Space Localization 

      Mizera, Sebastian (University of Waterloo, 2019-08-19)
      We propose that intersection numbers of certain cohomology classes on the moduli space of genus-zero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute tree-level scattering amplitudes in quantum field ...

      Mastromattei, Christian (University of Waterloo, 2017-10-25)
      This thesis assesses the theoretical performance of a realistic multi-node quantum repeater that is implementable with current technology. A quantum repeater, by definition, allows for communication rates in a channel to ...
    • 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 ...
    • Atomic Force Microscopy Study of Model Lipid Monolayers 

      Rozina, Tamara (University of Waterloo, 2012-09-26)
      Alzheimer's Disease (AD) is a neurodegenerative disorder that is prevalent among the elderly population. Aß protein has been heavily implicated in the pathogenesis of AD. This protein in its fibrillar form is a major ...
    • Augmenting Quantum Mechanics with Artificial Intelligence 

      Torlai, Giacomo (University of Waterloo, 2018-12-04)
      The simulation of quantum matter with classical hardware plays a central role in the discovery and development of quantum many-body systems, with far-reaching implications in condensed matter physics and quantum technologies. ...
    • Benchmarking a self-consistent field theory for small amphiphilic molecules 

      Thompson, Russell B.; Jebb, T.; Wen, Y. (RSC publishing, 2012-08-14)
      A minimalist self-consistent field theory for small amphiphilic molecules is presented. The equations for this model are less involved than those for block copolymers and are easily implemented computationally. A new ...
    • Bichromatic dressing of Rydberg atoms and on the correctness of many-mode Floquet theory 

      Poertner, Adam (University of Waterloo, 2020-01-20)
      Many-mode Floquet theory [T.-S. Ho, S.-I. Chu, and J. V. Tietz, Chem. Phys. Lett. 96, 464 (1983)] was designed as an extension of Floquet theory suitable for solving the time-dependent Schrodinger equation with multiple ...
    • Bidirectional mapping between self-consistent field theory and molecular dynamics 

      Thompson, Russell B.; Sewell, Thomas; Rasmussen, Kim; Bedrov, Dmitry; Smith, Grant (AIP Publishing, 2007-10-08)
      A bidirectional mapping scheme that bridges particle-based and field-based descriptions for polymers is presented. Initial application is made to immiscible homopolymer blends. The forward mapping (upscaling) approach ...
    • Biophysical Modelling of Antimicrobial Peptide’s Interactions with Phospholipid and Lipopolysaccharide Membranes 

      Nourbakhsh, Shokoofeh (University of Waterloo, 2019-05-23)
      Antimicrobial peptides (AMPs) are naturally-occurring peptide antibiotics. The way they work has inspired a vigorous search for optimized peptide antibiotics for fighting resistant bacteria. Cationic AMPs cleverly utilize ...
    • 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 Pseudo-Topological 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 ...
    • 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 ...
    • 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 ...
