    • Advancing Techniques for Detecting Dwarf Satellite Populations Beyond the Local Group 

      Xi, Chengyu (University of Waterloo, 2022-05-20)
      This thesis includes material from three papers that develop techniques for quantifying faint dwarf satellite populations outside the Local Group. Dwarf satellites are important for our understanding of small-scale structure ...
    • Advancing the robustness of polarization and time bin quantum key distribution for free-space channels 

      Tannous, Ramy (University of Waterloo, 2023-05-15)

    • Adventures in Holography 

      Razieh, Pourhasan (University of Waterloo, 2014-07-11)
      In this thesis, inspired by the holographic theories, we study a variety of interesting problems in gravity, condensed matter and cosmology. First, we explore the entanglement entropy of a general region in a theory of ...
    • An ALMA View of Molecular Gas in Brightest Cluster Galaxies 

      Vantyghem, Adrian (University of Waterloo, 2018-09-25)
      In this thesis I use ALMA observations to map the distribution and kinematics of molecular gas in the brightest cluster galaxies of three galaxy clusters: 2A0335+096, RXJ0821+0752, and RXCJ1504-0248. The goal is to understand ...
    • An alternative derivation of orbital-free density functional theory 

      Thompson, Russell B. (AIP, 2019-05-28)
      Polymer self-consistent field theory techniques are used to derive quantum density functional theory without the use of the theorems of density functional theory. Instead, a free energy is obtained from a partition function ...
    • Aluminium-Palladium Transition Edge Sensors 

      Persaud, Lauren Margaret (University of Waterloo, 2008-09-15)
      A superconducting Transition Edge Sensor (TES) can be used to make the most sensitive thermometer which operates in a very narrow temperature range. The thin film bi-layer fabrication details are discussed as well as ...
    • Amended Model of Large Scale Dark Matter Structure 

      Chen, Alice (University of Waterloo, 2020-09-03)
