Electron transport in semiconducting nanowires and quantum dots
(University of Waterloo, 2017-01-10)Single electrons confined in electrostatic quantum dots are a promising platform for realizing spin based quantum information processing. In this scheme, the spin of each electron is encoded as a qubit, and can be manipulated ... -
Electron-induced carbon tetrachloride Adsorption on Ice
(University of Waterloo, 2013-04-26)Charge-induced adsorption is a subject of significance to environmental and biological systems. Ice surface is believed to get charged with potassium deposition. Compared to uncharged ice film, the work function of charged ... -
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 ... -
Electronic Pre-Compensation of Intra-Channel Nonlinearity in a 10Gb/s Optical Transmission System
(University of Waterloo, 2007-07-30)We introduce several new algorithms for compensating intra channel nonlinearities in lightwave systems through electronic predistortion. These were optimized and modeled assuming realistic conditions at Nortel and ... -
Electronic Transport Properties in Single-layer CVD graphene
(University of Waterloo, 2023-01-23)Graphene is a two-dimensional material of carbon atoms possessing a metallic nature and the low-energy quasiparticles behave as massless Dirac fermions. The unique electronic properties of graphene inspire many researches ... -
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 ... -
Electrostatic Modification of Phospholipid and Lipopolysaccharide Membranes
(University of Waterloo, 2012-05-23)Biological membranes are quasi two-dimensional self-assembled structure, primarily serving as a barrier to the leakage of cell’s contents. The main constituents of biological membrane are various amphiphilic lipids that ... -
The electrostatic potential in a finite ionic crystal
(University of Waterloo, 1972-11-01)This thesis is written in two parts. In Part One, we develop a new method for evaluating three dimensional lattice summations and apply it to the evaluation of the electrostatic potential of a finite ionic crystal. We then ... -
Electrostatics of the Binding and Bending of Lipid Bilayers: Charge-Correlation Forces and Preferred Curvatures
(University of Waterloo, 2004)Lipid bilayers are key components of biomembranes; they are self-assembled two-dimensional structures, primarily serving as barriers to the leakage of cell's contents. Lipid bilayers are typically charged in aqueous ... -
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 ... -
Emergent Fields, Flat Bands and Phase Competition: A Study in Magnetic Pyrochlore Systems
(University of Waterloo, 2020-09-18)We investigate spins models on the pyrochlore and the breathing pyrochlore lattice. Specifically, we study polarized neutron scattering in classical spin ice modelled via Ising spins with anti-ferromagnetic interactions. ... -
Emergent Matter of Quantum Geometry
(University of Waterloo, 2009-08-14)This thesis studies matter emergent as topological excitations of quantum geometry in quantum gravity models. In these models, states are framed four-valent spin networks embedded in a topological three manifold, and ... -
Emulation of Anyonic Statistics using High-Fidelity NMR Quantum Information Processing (QIP) Techniques
