Increased interference fringe visibility from the post-fabrication heat treatment of a perfect crystal silicon neutron interferometer
(AIP Publishing, 2018-02-08)We find that annealing a previously chemically etched interferometer at 800 degrees C dramatically increased the interference fringe visibility from 23% to 90%. The Bragg plane misalignments were also measured before and ... -
Indium Antimonide Plasmonic Nanostructures for Tunable Terahertz Sources
(University of Waterloo, 2022-08-23)In this work, procedures were successfully created and deployed for the development, characterization, and study of indium antimonide nanostructures as well as their terahertz plasmonic response. Using molecular beam ... -

Information Flow In Black Hole Equilibration
(University of Waterloo, 2021-08-11)We study black hole evaporation and equilibration in the doubly holographic AEM4Z model, which consists of a double sided black hole in JT gravity with holographic matter. At t=0, the right side of the black hole is coupled ... -
Initialization and characterization of open quantum systems
(University of Waterloo, 2015-08-21)In this thesis we address three topics of open quantum systems theory. The first concerns the operational characterization of an open quantum system. We develop a graphical calculus for open quantum systems and use it to ... -
Instabilities in Higher-Dimensional Theories of Gravity
(University of Waterloo, 2006)A number of models of nature incorporate dimensions beyond our observed four. In this thesis we examine some examples and consequences of classical instabilities that emerge in the higher-dimensional theories of gravity ... -
Integrability in AdS/CFT: Exacts Results for Correlation Functions
(University of Waterloo, 2012-06-14)We report on the first systematic study of correlation functions in N=4 super Yang-Mills theory using integrability techniques. In particular, we show how to compute three- and four- point functions of single-trace ... -
Intense laser field ionization of atom and molecular ion
(University of Waterloo, 2008-01-24)In order to understand how does the intense laser interact with matter we first of all study the ionization process. In this highly nonlinear region the conventional perturbation theory will fail to predict the experimental ... -
Interaction of Nanosecond and Femtosecond Laser Pulses with Carbon: Deposition of Carbon Films having Novel Compositions
(University of Waterloo, 2008-05-22)A comparison of the composition and structure of carbon films deposited by ns and fs laser ablation of graphite is the subject of this thesis. In addition, the effect of irradiation on the surface of graphite has been ... -
Interactions of Cationic Peptides and Ions with Negatively Charged Lipid Bilayers
(University of Waterloo, 2006)In this thesis we study the interactions of ions and cationic peptides with a negatively charged lipid bilayer in an ionic solution where the electrostatic interactions are screened. <br /><br /> We first examine the ... -
Interactions, Entanglement, and Anomalies in Topological Semimetals
(University of Waterloo, 2023-08-04)Topology and symmetry have become one of the backbones of modern condensed matter physics. These concepts play a large role in determining the possible effects of interactions and entanglement in both gapped and gapless ... -
Interplay of Disorder and Transverse-Field Induced Quantum Fluctuations in the LiHo_xY_{1-x}F_4 Ising Magnetic Material
