1H MAS NMR Study of Water on Pd-MCM-41
(University of Waterloo, 2015-06-18)Hydrogen spillover represents one of the most promising avenues to achieve hydrogen storage at the density required for transportation applications. The spillover phenomenon, however, is a topic of much debate, with many ... -
A 4d Lorentzian Spin Foam Model With Timelike Surfaces
(University of Waterloo, 2010-10-07)We construct a 4d Lorentzian spin foam model capable of describing both spacelike and timelike surfaces. To do so we use a coherent state approach inspired by the Riemannian FK model. Using the coherent state method we ... -
Abundance Matching with the Galaxies of the Virgo Cluster and the Stellar-to-Halo Mass Relation
(University of Waterloo, 2012-09-27)Using data from the Next Generation Virgo Cluster Survey and high-resolution simulations of Virgo cluster-like halos, we determine the stellar-to-halo mass relation (SHMR) for subhalos, using the technique of abundance ... -
Adhesion of Two Cylindrical Particles to a Soft Membrane Tube
(University of Waterloo, 2012-09-26)The interaction of nanoparticles with biological systems, especially interactions with cell membranes, has been a subject of active research due to its numerous applications in many areas of soft-matter and biological ... -
Adventures in Holography
(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 ... -
Aluminium-Palladium Transition Edge Sensors
(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 ... -
Analytical and Numerical Studies of 2D XY Models with Ring Exchange
(University of Waterloo, 2012-08-31)In this thesis we take several different analytic and numerical approaches to studying the classical J-K model. This model describes an interacting many-body system of spins with continuous symmetry which interact via ... -
An apparatus for studying interactions between Rydberg atoms and metal surfaces
(University of Waterloo, 2007-09-27)A system suitable for studying interactions between ⁸⁷Rb Rydberg atoms and metal surfaces has been constructed. This thesis describes the design and construction of the apparatus, and some test results. Atoms in a vapor ... -
Applications of Adiabatic Approximation to One- and Two-electron Phenomena in Strong Laser Fields
(University of Waterloo, 2010-12-20)The adiabatic approximation is a natural approach for the description of phenomena induced by low frequency laser radiation because the ratio of the laser frequency to the characteristic frequency of an atom or a molecule ... -
Applications of the Wormlike Chain Model in Polymer Physics: Self-consistent Field Theory
(University of Waterloo, 2013-04-30)The self-consistent field theory (SCFT) has reveived a great success in prediction of the physical properties of a variety of polymeric systems in the recent two decades. However, the traditional SCFT is based on the ... -
Atomic Force Microscopy Study of Model Lipid Monolayers
(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 ... -
Black Hole Thermodynamics and the Tunnelling Method for Particle Emission
(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
(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 ... -
Can Lensing Measure The Shape Of Dark Matter Halos?
(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, ... -
