Investigation of Ultrafast Carrier Dynamics in InGaN/GaN‐Based Nanostructures Using Femtosecond Pump–Probe Absorption Spectroscopy
(Springer USWiley Periodicals, Inc., 2021-10)
Deterministic-Kinetic Computational Analyses of Expansion Flows and Current-Carrying Plasmas
(2021)
Spacecraft electric propulsion (EP) takes advantage of the ability of electric and magnetic fields to accelerate plasmas to high velocities to generate efficient thrust. The thermionic hollow cathode is a critical component ...
Into the Rainbow: Kinetics of the Bacterial Reaction Center Using Broadband Two-Dimensional Electronic Spectroscopy
(2021)
Photosynthesis is a process by which light is converted to chemical energy, and which is responsible for nearly all life on Earth. A more complete understanding of the mechanisms behind photosynthesis, particularly the ...
Understanding the Optical and Photophysical Properties of Organic and Hybrid Macromolecules and Polymers for Solar Cell Application
(2021)
Organic solar cell materials represent a better sustainable alternative relative to inorganic materials in terms of lower cost, ease of large-scale processing, better absorptivity, ease of tunability, and unique flexibility ...
Mechanisms of Extreme Dynamics in Femtosecond Laser Interaction With Materials; Ultrafast Mass Transport, Desorption, Formation of Periodic Structures, and Oxidation
(2021)
This thesis focused the understanding of the mechanisms responsible for different morphologies that emerge upon ultrafast irradiation. These morphological changes include the formation laser-induced periodic surface ...
Novel Low-Cost Scalable Nanofabrication Technologies by Soft Lithography, Plasmonic Lithography, and Electrochemical Processes
(2021)
As wide variety of devices such as optical devices, wearable devices, and color filters have become more common, the demand for technologies which can fabricate these devices at a low cost is at an all-time high. ...
Quantum Inspired Machine Learning Algorithms for Adaptive Radiotherapy
(2021)
Adaptive radiotherapy (ART) refers to the modification of radiotherapy treatment plans in response to patient anatomical and physiological changes over the course of treatment and has been recognized as an important step ...
Dressings and Asymptotic Symmetries in Quantum Field Theory
(2021)
In quantum field theories with massless gauge bosons, the conventional formulation of scattering amplitudes in terms of momentum eigenstates lead to infrared divergences. To resolve this one should dress charged particles ...
Revisiting Unsolved Mysteries: A Journey Into Bulk and Surface Characteristics of Samarium Hexaboride Using Transport Measurements
(2021)
Samarium hexaboride (SmB6) is a correlated material in which strong f-d interactions lead to the opening of a small hybridization gap below 100 K at the Fermi energy. A long-standing mystery in SmB6 was the plateau in ...
Searches for the Rare Decay of the Higgs Boson to Two Muons and for New Physics in Dilepton Final States with the ATLAS Experiment
(2021)
This thesis presents two studies: a search for rare dimuon decay of the Higgs boson and a search for new physics with non-resonant phenomena at the TeV mass scale with dilepton final states.
Both studies investigate an ...
