Effects of molecular crowding and confinement on the spatial organization of a biopolymer
(Royal Society of Chemistry, 2016-10-25)A chain molecule can be entropically collapsed in a crowded medium in a free or confined space. Here, we present a unified view of how molecular crowding collapses a flexible polymer in three distinct spaces: free, ... -
The Effects of Quantum Error Correction on Noisy Systems
(University of Waterloo, 2018-08-23)Full accuracy simulations of quantum systems are very costly, and as a result most studies of quantum error correction assume a probabilistic Pauli error model, largely because such errors can be e ciently simulated. ... -
The Effects of Uniform Acceleration on the Correlation Harvesting
(University of Waterloo, 2023-09-22)Quantum field theory (QFT) in curved spacetime focuses on the analysis of quantum fields—representing fundamental particles and their interactions—within a curved spacetime geometry, accounting for relativistic effects. Among ... -
Efficient Characterization of a Unitary Quantum Gate via a Projective Rabi Experiment
(University of Waterloo, 2023-01-09)In this thesis, we introduce a novel randomization-based protocol for estimation of parameters in a sparse Hamiltonian. This is achieved via a projective Rabi experiment which interleaves projective channels between ... -
Efficient polyyne formation by ns and fs laser-induced breakdown in ethylene and acetylene gas flow
(Elsevier, 2019-11)We studied polyyne formation by gas phase laser-induced breakdown in ethylene and acetylene gas flow using ns and fs lasers. The results show that acetylene is the most efficient target molecule for generating polyynes ... -
Elastic moduli of multiblock copolymers in the lamellar phase
(AIP Publishing, 2004-02-22)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 self-consistent field theory method, and ... -
Electric field sensing near the surface microstructure of an atom chip using cold Rydberg atoms
(University of Waterloo, 2013-05-27)This thesis reports experimental observations of electric fields using Rydberg atoms, including dc field measurements near the surface of an atom chip, and demonstration of measurement techniques for ac fields far from ... -
Electric-field-dependent variable-range hopping conductance in quasi-two-dimensional systems: Application to PrBa2Cu3O7-y-based superconductor–normal-metal–superconductor junctions
(American Physical Society, 1996-03)We have calculated the hopping conductivity of quasi-two-dimensional systems by using the variable-range hopping conduction mechanism in the presence of an electric field. We considered that the localized states are randomly ... -
Electric-field-dependent variable-range hopping conduction in PrBa2Cu307-y
(Taylor & Francis, 1997-02)The variable-range hopping conductivities of quasi-two-dimensional systems in electric fields were calculated for the cases of both constant and energy-dependent densities of states. The localized states were considered ... -
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
