SelfAssembly of Amphiphilic NanoparticleCoil “Tadpole” Macromolecules
(American Chemical Society, 2004)None. 
Origins of Elastic Properties in Ordered Block Copolymer/Nanoparticle Composites
(American Chemical Society, 2004)We predict a diblock copolymer melt in the lamellar phase with added spherical nanoparticles that have an affinity for one block to have a lower tensile modulus than a pure diblock copolymer system. This weakening is due ... 
Elastic moduli of multiblock copolymers in the lamellar phase
(AIP Publishing, 20040222)We study the linear elastic response of multiblock copolymer melts in the lamellar phase, where the molecules are composed of tethered symmetric AB diblock copolymers. We use a selfconsistent field theory method, and ... 
Minimal model for the secondary structures and conformational conversions in proteins
(University of Waterloo, 2005)Better understanding of protein folding process can provide physical insights on the function of proteins and makes it possible to benefit from genetic information accumulated so far. Protein folding process normally ... 
TaubNUT Spacetime in the (A)dS/CFT and MTheory
(University of Waterloo, 2005)In the following thesis, I will conduct a thermodynamic analysis of the TaubNUT spacetime in various dimensions, as well as show uses for TaubNUT and other HyperKahler spacetimes. <br /><br /> Thermodynamic analysis ... 
Monte Carlo Study of the Magnetic Flux Lattice Fluctuations in High<em>T<sub>c</sub></em> Superconductors
(University of Waterloo, 2005)By allowing to measure the magnetic field distribution inside a material, muon spin rotation experiments have the potential to provide valuable information about microscopic properties of hightemperature superconductors. ... 
Nematic ordering of wormlike polymers
(University of Waterloo, 2005)In this thesis, based on the Onsager excluded volume interaction model, two nematic ordering problems of wormlike (semiflexible) polymer are studied: one is to investigate the isotropicnematic interface of polymers for ... 
Topological methods in quantum gravity
(University of Waterloo, 2005)The main technical problem with background independent approaches to quantum gravity is inapplicability of standard quantum field theory methods. New methods are needed which would be adapted to the basic principles ... 
Fast Stochastic Global Optimization Methods and Their Applications to Cluster Crystallization and Protein Folding
(University of Waterloo, 2005)Two global optimization methods are proposed in this thesis. They are the multicanonical basin hopping (MUBH) method and the basin paving (BP) method. <br /><br /> The MUBH method combines the basin hopping (BH) ... 
The Development of an Average, Anatomically Based, Young Adult, GRIN Eye Model
(University of Waterloo, 2005)The purpose of this thesis is to describe the development of an anatomically based, young adult eye model, which includes a crystalline lens with a gradient refractive index (GRIN). This model will then be used to ... 
Spectroscopy of selected metalcontaining diatomic molecules
(University of Waterloo, 2005)Fourier transform infrared emission spectra of MnH and MnD were observed in the ground <em>X</em><sup>7</sup>σ<sup>+</sup> electronic state. The vibrationrotation bands from <em>v</em> = 1 to 0 to <em>v</em> = ... 
Observation of Resonant Electric DipoleDipole Interactions Between Cold Rydberg Atoms Using Microwave Spectroscopy
(University of Waterloo, 2006)This thesis reports the first observation of the resonant electric dipoledipole interaction between cold Rydberg atoms using microwave spectroscopy, the observation of the magnetic field suppression of resonant interactions, ... 
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 ... 
Multifrequency Raman Generation in the Transient Regime
(University of Waterloo, 2006)Two colour pumping was used to investigate the shortpulse technique of Multifrequency Raman Generation (MRG) in the transient regime of Raman scattering. In the course of this study we have demonstrated the ability to ... 
Specific Heat of the Dilute, DipolarCoupled, Ising Magnet LiHo<sub><em>x</em></sub>Y<sub>1<em>x</em></sub>F<sub>4</sub>
(University of Waterloo, 2006)The system LiHo<sub><em>x</em></sub>Y<sub>1<em>x</em></sub>F<sub>4</sub> is a nearly perfect example of a dilute, dipolarcoupled Ising magnet and, as such, it is an ideal testing ground for many theories in statistical ... 
Higher dimensional TaubNUT spaces and applications
(University of Waterloo, 2006)In the first part of this thesis we discuss classes of new exact NUTcharged solutions in four dimensions and higher, while in the remainder of the thesis we make a study of their properties and their possible applications. ... 
Development and Characterization of a Regeneratively Amplified Ultrafast Laser System with an AllGlass Stretcher and Compressor
