Ultra-low temperature dilatometry
(University of Waterloo, 2010-10-28)
This thesis presents research of two novel magnetic materials, LiHoF4 and Tb2Ti2O7. Experiments were performed at low temperatures and in an applied magnetic field to study thermal expansion and magnetostriction using a ...
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 ...
Femtosecond Laser Induced Polyyne Formation
(University of Waterloo, 2010-10-01)
Polyyne molecules were produced as a result of the femtosecond laser irradiation of
liquid acetone (CH3)2CO and alkane molecules hexane C6H14 and octane C8H18 using
800 nm, 100 fs duration pulses. These polyynes have ...
Universal Control in 1e-2n Spin System Utilizing Anisotropic Hyperfine Interactions
(University of Waterloo, 2010-09-30)
ESR quantum computing presents faster means to perform gates on nuclear spins than the traditional NMR methods. This means ESR is a test-bed that can potentially be useful in ways that are not possible with NMR. The first ...
Membrane-Disrupting Activity of Antimicrobial Peptides and the Electrostatic Bending of Membranes
(University of Waterloo, 2010-05-21)
Antimicrobial peptides (AMPs) are not only fast microbe-killing molecules deployed in the host defense of living organisms but also offer valuable lessons for developing new therapeutic agents. While the mode of action of ...
Electron-phonon Coupling in Quasi-Two-Dimensional Correlated Systems
(University of Waterloo, 2010-06-18)
Over the past 20 years a great deal of progress has been made towards understanding the physics of the high-temperature (high-Tc) cuprate superconductors. Much of the low- energy physics of these materials appears to be ...
Emergence and Phenomenology in Quantum Gravity
(University of Waterloo, 2010-07-09)
In this thesis we investigate two approaches to quantum gravity. The first is the emergence of gravity from a discrete fundamental theory, and the second is the direct quantisation of gravity. For the first we develop tools ...
Optical Fiber Sensors for Temperature and Strain Measurement
(University of Waterloo, 2010-12-09)
Optical fiber sensors have already been developed from the experimental stage to practical applications in the past 20 years. There is no doubt that this technology can bring a wealth of applications, ranging from sensors ...
Electrostatic Interactions of Peptides with Lipid Membranes: Competitive Binding between Cationic Peptides and Divalent Counterions
(University of Waterloo, 2010-09-30)
In this thesis, we investigate a variety of problems involving the interaction of cationic peptides with lipid membranes. To this end we adopt Poisson-Boltzmann (PB) theory and coarse-grained models of these molecules. We ...
Group-finding with photometric redshifts: The Photo-z Probability Peaks algorithm
(University of Waterloo, 2010-01-25)
We present a galaxy group-finding algorithm, the Photo-z Probability Peaks (P3) algorithm, optimized for locating small galaxy groups using photometric redshift data by searching for peaks in the signal-to-noise of the ...
