Instabilities in HigherDimensional 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 higherdimensional theories of gravity ... 
Integrability in AdS/CFT: Exacts Results for Correlation Functions
(University of Waterloo, 20120614)We report on the first systematic study of correlation functions in N=4 super YangMills theory using integrability techniques. In particular, we show how to compute three and four point functions of singletrace ... 
Intense laser field ionization of atom and molecular ion
(University of Waterloo, 20080124)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, 20080522)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 ... 
Interplay of Disorder and TransverseField Induced Quantum Fluctuations in the LiHo_xY_{1x}F_4 Ising Magnetic Material
(University of Waterloo, 20080825)The LiHo_xY_{1x}F_4 magnetic material in a transverse magnetic field B_x perpendicular to the Ising spin direction has long been used to study tunable quantum phase transitions in pure and random disordered systems. We ... 
Interpolated Collision Model Formalism
(University of Waterloo, 20200916)The dynamics of open quantum systems (i.e., of quantum systems interacting with an uncontrolled environment) forms the basis of numerous active areas of research from quantum thermodynamics to quantum computing. One approach ... 
Inverse Partial Fluorescence Yield Spectroscopy
(University of Waterloo, 20110830)Xray absorption spectroscopy (XAS) is a powerful probe of electronic and spatial structure that has been at the heart of many advances in physics, biology, chemistry, engineering and the earth sciences. Unfortunately, the ... 
Investigating Photonic Quantum Computation
(University of Waterloo, 20070928)The use of photons as qubits is a promising implementation for quantum computation. The inability of photons to interact, especially with the environment, makes them an ideal physical candidate. However, this also makes ... 
An Investigation and Application of the Finite Difference Time Domain Method as a Tool for Solving Equalization Problems in Acoustics
(University of Waterloo, 20100125)This thesis investigates the issues in deriving the Finite Di erence Time Domain Method, including the derivation of a unique method for exciting an FDTD system that is physically realistic in terms of acoustics. It is ... 
An investigation of low energy quasiparticle excitations via thermal conductivity measurements
(University of Waterloo, 20121026)Thermal conductivity measurements are made on a variety of systems in order to probe low energy quasiparticle excitations. In particular, thermal conductivity measurements were made on the iron based superconducting ... 
An investigation of low energy quasiparticle excitations via thermal transport measurements
(University of Waterloo, 20170616)Thermal transport measurements can provide a unique perspective of the nature of a system by exploring the behaviour of the low energy excitations from the ground state. Delocalized quasiparticle excitations can affect ... 
Investigation of Photon Interactions with Semiconductor Quantum Dot Devices for Quantum Communication Applications
