In this thesis, inspired by the holographic theories, we study a variety of interesting problems in gravity, condensed matter and cosmology. First, we explore the entanglement entropy of a general region in a theory of ...
• #### An ALMA View of Molecular Gas in Brightest Cluster Galaxies ﻿

(University of Waterloo, 2018-09-25)
In this thesis I use ALMA observations to map the distribution and kinematics of molecular gas in the brightest cluster galaxies of three galaxy clusters: 2A0335+096, RXJ0821+0752, and RXCJ1504-0248. The goal is to understand ...
• #### Amplitudes in the Spin Foam Approach to Quantum Gravity ﻿

(University of Waterloo, 2017-07-31)
In this thesis, we study a Spin Foam model for 4D Riemannian quantum gravity, and propose a new way of imposing the simplicity constraints that uses the recently developed holomorphic representation. Rather than imposing ...
• #### 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 ...

(University of Waterloo, 2013-04-30)
The self-consistent field theory (SCFT) has reveived a great success in prediction of the physical properties of a variety of polymeric systems in the recent two decades. However, the traditional SCFT is based on the ...
• #### Aspects of Nonlocality: from Particles to Black Holes ﻿

(University of Waterloo, 2016-05-06)
This dissertation is a collection of works on different aspects of the following subjects: causal set--continuum correspondence, wave propagation on causal sets, nonlocal quantum field theory, potential connection between ...
• #### Aspects of Quantum Information and AdS/CFT Duality ﻿

(University of Waterloo, 2021-05-17)
This thesis considers four different aspects of quantum information, AdS/CFT duality, and the interplay between them. First, we study the holographic complexity conjectures in detail for rotating black holes. We focus ...
• #### Aspects of Scattering Amplitudes and Moduli Space Localization ﻿

(University of Waterloo, 2019-08-19)
We propose that intersection numbers of certain cohomology classes on the moduli space of genus-zero Riemann surfaces with $n$ punctures, $\mathcal{M}_{0,n}$, compute tree-level scattering amplitudes in quantum field ...
• #### At the Corner of Space and Time ﻿

(University of Waterloo, 2019-12-09)
We perform a rigorous piecewise-flat discretization of classical general relativity in the first-order formulation, in both 2+1 and 3+1 dimensions, carefully keeping track of curvature and torsion via holonomies. We show ...
• #### Augmenting Quantum Mechanics with Artificial Intelligence ﻿

(University of Waterloo, 2018-12-04)
The simulation of quantum matter with classical hardware plays a central role in the discovery and development of quantum many-body systems, with far-reaching implications in condensed matter physics and quantum technologies. ...
• #### Biophysical Modelling of Antimicrobial Peptide’s Interactions with Phospholipid and Lipopolysaccharide Membranes ﻿

(University of Waterloo, 2019-05-23)
Antimicrobial peptides (AMPs) are naturally-occurring peptide antibiotics. The way they work has inspired a vigorous search for optimized peptide antibiotics for fighting resistant bacteria. Cationic AMPs cleverly utilize ...
• #### Black Hole Thermodynamics and the Tunnelling Method for Particle Emission ﻿

(University of Waterloo, 2008-08-29)
The semi-classical black hole tunnelling method is a useful technique to calculate black hole temperature and understand black hole thermodynamics. I will investigate the black hole tunnelling method in detail. I will ...
• #### Born Geometry ﻿

(University of Waterloo, 2020-04-21)
In this thesis, we summarize the work which we authored or co-authored during our PhD studies and also present additional details and ideas that are not found elsewhere. The main topic is the study of T-duality in theoretical ...
• #### Canonical Structure and Conservation Laws of General Relativity on Null Surfaces and at Null Infinity ﻿

(University of Waterloo, 2021-01-12)
The first part of this thesis addresses the canonical structure of general relativity on generic null surfaces. The pre-symplectic potential of metric general relativity, evaluated on a null surface, is decomposed into ...

(University of Waterloo, 2020-05-13)
This thesis is motivated by the many sensing applications of carbon nanotube (CNT) nano-electromechanical systems (NEMS), both previous state-of-the-art demonstrations and proposed new uses. This research is particularly ...
• #### Causal Models for a Quantum World ﻿

(University of Waterloo, 2016-05-18)
Quantum mechanics has achieved unparalleled success as an operational theory, describing a wide range of experiments to remarkable accuracy. However, the physical foundations on which it rests remain as puzzling as they ...
