FieldOrientation Coupling Effects in Nematic Liquid Crystal Cells
(University of Waterloo, 20191023)Using the continuum Landaude Gennes model for the nematic liquid crystal (NLC) phase, we study the equilibrium behaviour of nematic cells, accounting for the coupling between external fields and nematic order. This is ... 
FieldSweep Control in Magnetic Resonance and kspace Analysis
(University of Waterloo, 20191030)In a general magnetic resonance experiment, resonant radiofrequency or microwave fields are applied to an ensemble of electron or nuclear spins to determine their magnetic interactions with their local environment. These ... 
Flag faulttolerant error correction for cyclic CSS codes
(University of Waterloo, 20180620)Faulttolerant quantum error correction (FTEC) protocol is one of the most important components for a faulttolerant simulation of a quantum circuit. It helps prevent error accumulation during the process which may cause ... 
Fluctuation correction for the critical transition of symmetric homopolymer blends
(AIP, 201707)Monte Carlo simulations are performed on structurally symmetric binary homopolymer blends over a wide range of invariant polymerization indexes, N. A finitesize scaling analysis reveals that certain critical exponents ... 
Fluctuation effects in blends of A+B homopolymers with AB diblock copolymer
(AIP, 201805)Fieldtheoretic simulations (FTS) are performed on ternary blends of A and Btype homopolymers of polymerization N_h and symmetric AB diblock copolymer of polymerization N_c. Unlike previous studies, our FTS are conducted ... 
Forays into Mathematical Physics
(University of Waterloo, 20070927)Two different works in mathematical physics are presented: A construction of conformal infinity in null and spatial directions is constructed for the Rainbowflat spacetime corresponding to doubly special relativity. ... 
Fragmentation Dynamics of Triatomic Molecules in Femtosecond Laser Pulses Probed by Coulomb Explosion Imaging
(University of Waterloo, 20130619)In this thesis we have utilized fewcycle pulses in the range 1015s, to initiate CE to allow us to image the structure, dynamics, and kinetics of ionization and dissociation of triatomic molecules. We have made a series ... 
Free Space Quantum Key Distribution to Moving Platforms
(University of Waterloo, 20170824)The quantum space age has officially begun and many important milestones and achievements have recently been demonstrated, such as the exciting launch and results of the first quantum demonstration satellite, Micius. ... 
Frontiers of Gravity: Astrophysical Environments, Ringdown Nonlinearities and the Semiclassical Approximation
(University of Waterloo, 20210122)Einstein’s general relativity is based on a tensorial, nonlinear equation for the spacetime metric. The gravitational interaction is however so weak that, in most circumstances, the equations can be solved perturbatively. ... 
Fundamental Tests of Quantum Mechanics using TwoPhoton Entanglement
(University of Waterloo, 20140430)In this thesis, we experimentally test fundamental properties of quantum mechanics, namely nonlocality (in the form of three new families of Bell's inequalities) and the symmetry of envariance. To accomplish these we ... 
Galactic Molecular Dust Clumps using SCUBA2  Effects of HII Regions on Star Formation
(University of Waterloo, 20180921)I present findings from a broad array of SCUBA2 observations. The sample consists of 38 SCUBA2 images targeted near mature, galactic, HII regions of the Sharpless "Sh2" or BlitzStarkFich "BFS" catalogue. In 31 of those ... 
Galaxy Formation at Redshift ~0.75: A Low Mass Survey & The Role of Environment
(University of Waterloo, 20110929)The majority of galaxy formation studies which explore beyond local redshifts do not typically probe down to the dwarf galaxy stellar mass range of ∼ 10^9 Msun . Thus trends in the observed evolution or characteristics of ... 
Galaxy Morphology In Cluster Environments
(University of Waterloo, 20170825)It is a well known fact that cluster environments favour earlytype galaxies over late type. However, the physical origin of the correlation remains uncertain. We focus specifically on the external environmental mechanisms ... 
Galaxy Transformations in the Last 5 Billion Years
(University of Waterloo, 20100901)It has become clear that the global star formation rate in the Universe has been decreasing since at least z~1, and blue, starforming galaxies are transformed into red, passive galaxies through one or more processes. The ... 
Gauge Models of Topological Phases and Applications to Quantum Gravity
(University of Waterloo, 20180626)In 2+1 dimensions, gravity is an SU(2) topological gauge theory that can be written as BF theory. In the condensed matter literature, the Hamiltonian realization of BF theory for finite groups is known as the Kitaev model. ... 
Gauge Theory Dynamics and CalabiYau Moduli
(University of Waterloo, 20140702)We compute the exact partition function of two dimensional N=(2,2) supersymmetric gauge theories on S². For theories with SU(21)_A invariance, the partition function admits two equivalent representations corresponding to ... 
Generalized holographic dualities for metric gravity & Quantum geometry based on area variables
(University of Waterloo, 20200918)Holography holds promise for simplifying computations in quantum gravity. In part I of this thesis, we construct holographic boundary theories for linearized gravity, for a general family of finite or quasilocal boundaries, ... 
Generating Functionals for Spin Foam Amplitudes
(University of Waterloo, 20140925)Various approaches to Quantum Gravity such as Loop Quantum Gravity, Spin Foam Models and TensorGroup Field theories use invariant tensors on a group, called intertwiners, as the basic building block of transition amplitudes. ...
