Femtosecond Laser Pulses and Thin Metallic Films: Mixing in the Vapor Dome and the Solid State
(2023)
This thesis covers the different mechanisms for mixing thin films with ultrashort laser pulses and refining the techniques for use in morphologically- and heat-sensitive applications. The irradiating fluence accesses ...
Impacts of Collateral Effects and Spatial Heterogeneity on the Evolution of Resistance in Enterococcus
(2023)
Antibiotics are used to treat bacterial infections, as they can kill or inhibit the growth of bacterial populations. However, the misuse of antibiotics may also promote the evolution of drug resistance, reducing the efficacy ...
Dark Matter and Baryogenesis
(2023)
We first study dark matter within a hidden, or secluded, sector. A hidden sector that kinetically mixes with the Minimal Supersymmetric Standard Model provides simple and well-motivated dark matter candidates that possess ...
Generation, Optimization and Amplification of Ultrashort Infrared Pulses
(2023)
The development of few-cycle, ultra-intense laser sources in the long-wave infrared (LWIR, 8–12 μm) is of keen interest in many research fields, including molecular spectroscopy in the “fingerprint” region, laser-induced ...
Exploring Dark Matter Interactions: Extending the LUX-ZEPLIN Search to Non-Standard WIMP-Nucleon Interactions, Anomaly Finding Techniques, and Liquid Xenon Detector Characterization
(2023)
Dark matter is a prime mystery in modern physics. Independent measurements point to a quarter of the universe's mass-energy (and 85% by mass alone) being made up of a cold, collisionless species of matter. Its ubiquity in ...
Modeling Hydrodynamic Instabilities, Shocks, and Radiation Waves in High Energy Density Physics
(2023)
This thesis presents the computational design, modeling, and analysis of three experiments in high energy density physics, all of them concerning fundamental radiation flows. The first experiment is a laboratory astrophysics ...
Dark Energy and Growth of Structure in Modified-Gravity Theories
(2023)
The past two decades have witnessed the emergence and flourishing of precision cosmology. Vast amount of high-quality observational data, especially those of the large scale structure and the cosmic microwave background, ...
High-Energy-Density Field-Reversed Configurations for Sub-Microsecond Magnetized Target Fusion
(2023)
Magnetized target fusion (MTF) has gained popularity in recent decades as potentially a more economic route to fusion gain greater than unity in the laboratory. The magnetized liner inertial fusion (MagLIF) program on the ...
Observations of the Radiation Amplitude Zero effect and of the Diboson Longitudinal-Longitudinal Interactions in High pT Region using W+-Z Production with the ATLAS Detector
(2023)
This thesis focuses on the studies of di-boson polarization states in wpmz production, presenting two novel measurements using $pp$ collisions at a center-of-mass energy of $sqrt{s}=13$ TeV. The wz decaying to leptonic ...
Modeling Effects of Spatially Heterogeneous Acetylcholine on Neural Oscillations and Synaptic Plasticity
(2023)
Acetylcholine (ACh) is one of the brain’s most powerful neuromodulators and has been shown to influence numerous cognitive functions such as arousal, attention, learning and memory. Recent evidence suggests that cholinergic ...
