      Bohlouli-Zanjani, Parisa (University of Waterloo, 2003)
      In highly excited Rydberg atoms, the excited electron is in a large, loosely bound orbit. Hence, in contrast with the ground states, the Rydberg states are very sensitive to external electric field and can be ionized in ...

    • Hodge Theory for Geometrically Frustrated Magnetism 

      Chung, Kristian (University of Waterloo, 2022-09-29)
      We present an analytical formalism based on the concept of discrete differential forms and Hodge theory as a framework for understanding geometrically frustrated magnetism. The primary insight is to treat spins as a 1-form ...
    • Holographic Correspondence and Exploring New Regimes of AdS/CFT Duality 

      Park, Miok (University of Waterloo, 2013-06-21)
      We aim to have a comprehensive understanding of holographic correspondence and to demonstrate how the holographic correspondence (or renormalization) can be applied. Thus this thesis is divided into two parts. The first ...
    • Holographic Entanglement Entropy: RG Flows and Singular Surfaces 

      Singh, Ajay (University of Waterloo, 2012-08-23)
      Over the past decade, the AdS/CFT correspondence has proven to be a remarkable tool to study various properties of strongly coupled field theories. In the context of the holography, Ryu and Takayanagi have proposed an ...
    • Holographic Experiments on Defects 

      Wapler, Matthias Christian (University of Waterloo, 2009-09-03)
      Using the AdS/CFT correspondence, we study the anisotropic transport properties of both supersymmetric and non-supersymmetric matter fields on (2+1)-dimensional defects coupled to a (3+1)-dimensional N=4 SYM "heat bath". ...
    • Holographic Optical Manipulation of Trapped Ions for Quantum Simulation 

      Shih, Chung-You (University of Waterloo, 2019-09-26)
      Trapped ion is one of the leading platforms for quantum simulation experiment due to its long coherence time and high fidelity state initialization, detection, and manipulation. To individually address ions at a single-ion ...
    • Holographic studies of thermal gauge theories with flavour 

      Thomson, Rowan (University of Waterloo, 2007-09-12)
      The AdS/CFT correspondence and its extensions to more general gauge/gravity dualities have provided a powerful framework for the study of strongly coupled gauge theories. This thesis explores properties of a large class ...
    • Holography with a neutron interferometer 

      Sarenac, Dusan; Huber, Michael G.; Heacock, Benjamin; Arif, Muhammad; Clark, Charles W.; Cory, David G.; Shahi, Chandra B.; Pushin, Dimitry A. (The Optical Society, 2016-10-03)
      We use a Mach-Zehnder interferometer to perform neutron holography of a spiral phase plate. The object beam passes through a spiral phase plate, acquiring the phase twist characteristic of orbital angular momentum states. ...
    • Horizon Thermodynamics from Einstein's Equation of State 

      Hansen, Devin (University of Waterloo, 2017-04-28)
      The striking resemblance between geometric theories of gravity and thermodynamics suggests a more fundamental relationship between the two seemingly distinct theories. It has been postulated that the radial Einstein ...
    • How are molecular crowding and the spatial organization of a biopolymer interrelated 

      Jeon, Chanil; Hyeon, Changbong; Jung, Youngkyun; Ha, Bae-Yeun (Royal Society of Chemistry, 2016-10-21)
      In a crowded cellular interior, dissolved biomolecules or crowders exert excluded volume effects on other biomolecules, which in turn control various processes including protein aggregation and chromosome organization. As ...
    • Hunting for the Primordial Quenched Population in 2 < z < 2.5 COSMOS Protoclusters 

      Edward, Adit Harin (University of Waterloo, 2024-01-17)
      We present an analysis of the galaxy stellar mass function (SMF) of 14 known protoclusters between 2.0 < z < 2.5 in the COSMOS field, down to a mass limit of 10⁹ᐧ⁵ M⊙. We use existing photometric redshifts with a statistical ...
    • H₂¹⁸O and H₂¹⁶O in Intermediate Mass Star Formation Regions 

      Conrad, Mollie (University of Waterloo, 2018-09-20)
      While the process of low mass (LM) star formation is a well studied area of astrophysics, the formation of high mass (HM) stars is much more complicated. The study of intermediate mass (IM) star formation is expected to ...
