First-Principles Calculations on the Electronic, Optical, and Vibrational Properties of Ultrawide-Band-Gap Semiconductor Materials
(2019)
First-principles calculations enable an unprecedented atomistic insight to experimentally-observed phenomena on a massive scale. Such calculations can intelligently guide experimental efforts to save both human time and ...
Self-Assembly and Real-Space Modeling in Binary Hard-Particle and Quasicrystalline Systems
(2022)
In this thesis, I will show a fundamentally new way to understand and construct quasicrystal tilings based on a new formulation of the quasi-unit cell called layering. There are many methods for generating quasitilings ...
Search for New Particles Decaying to Diphotons in Proton-Proton Collisions at s = 13 TeV
(2021)
This thesis presents a search for new resonances decaying to diphotons in 139 fb−1 of proton-proton collision data produced by the Large Hadron Collider at a center of mass center of mass (COM) energy √s = 13 TeV. The ...
Long-Wave Infrared Supercontinuum Source and Sensor for Standoff Sensing and Trace Particle Identification
(2020)
This dissertation is based on the development of a long-wave infrared supercontinuum source, and the utilization of this source in a Fourier transform based standoff optical sensor. The spectra from trace particles ...
Optical Spectroscopy of Tungsten Carbide for Electron Electric Dipole Moment Search.
(2012)
Searching for a permanent electron electric dipole moment (EDM) is a powerful tool to probe for physics beyond the Standard Model. We identified the X3Delta1 ground state of tungsten carbide (WC) molecule as a candidate ...
Computational Study of Emergent Behavior in Active Matter Systems with Particle Shape
(2020)
Murmurations of birds, schools of fish, and herds of migrating animals are macroscale examples of self-propelled units exhibiting emergent collective behavior. We call such systems ``active matter''. On the colloidal scale, ...
Enhancing Understanding of Oxygenic Photosynthesis Using Two Dimensional Electronic Spectroscopy
(2019)
Many aspects of energy and charge transfer in oxygenic photosynthesis are still poorly understood at both the level of single pigments and multi-pigment complexes. At the single pigment level, chlorophylls and chlorophyll-like ...
Rydberg Molecules and Excitation of Lattice-Mixed Rydberg States in a Deep Ponderomotive Optical Lattice
(2021)
In this dissertation, I explore several aspects of Rydberg physics with laser spectroscopy. The experiments center around the use of a very deep, cavity-generated, one-dimensional optical lattice in a cold atom sample. The ...
The Plasma Water Reactor: A Geometric Approach to Scaling Electric Discharges for Water Treatment
(2019)
Advanced oxidation processes (AOPs) are established disinfection methods that can remove contaminants of emerging concern (CECs) by producing hydroxyl radicals and other reactive oxygen species (ROS) in situ. Production ...
Precision Measurements with Rydberg States of Rubidium
(2019)
Rydberg atoms can be excellent tools for precision metrology thanks to their long lifetimes and interactions with external fields and other atoms that scale with large powers of the principal quantum number. In this thesis ...
