Ab initio study of inorganic nanowires
Elizondo, Shelly L. (2006-07)Scope and Method of Study: In this work, we report simulations of the electronic structure pertaining to two types of quasi-one-dimensional nanostructures: silver and zinc-oxide nanotubes and nanowires. The electronic ... -
Anomaly mediated supersymmetry breaking and nonstandard neutrino oscillations
Anoka, Cyril Ojodume (2005-07)Scope and Method of Study: In this thesis, we propose four different scenarios that solves the tachyonic slepton mass problem of Anomaly Mediated Supersymmetry Breaking (AMSB). We also address the question of neutrino ... -
Antiferromagnetic spinor condensates in microwave dressing fields and optical lattices
Zhao, Lichao (2015-12)In this thesis, I present the design and construction of several experimental parts, e.g., a spin-flip Zeeman slower, a fast feedback circuit, and some magnetic field driving circuits. An efficient method of optimizing the ... -
Density functional theory and time-dependent DFT modeling of organic photovoltaic materials
Dai, Shuo (2017-12)This thesis has aimed to apply Density Functional Theory (DFT) and Time-dependent DFT (TD-DFT) method to design new organic material for small molecule organic photovoltaic (OPV) and molecules for tandem structure solar ... -
Development and applications of infrared structural biology
Kang, Zhouyang (2014-05)Aspartic acid (Asp), Glutamic acid (Glu) and Tyrosine (Tyr) often play critical roles at the active sites of proteins. Probing the structural dynamics of functionally important Asp/Glu and Tyr provides crucial information ... -
Development and Characterization of Mgb4o7 for Optically Stimulated Luminescence Dosimetry
Gustafson, Timothy David (2018-12-01)The objective of this study was to investigate MgB4O7 for optically stimulated luminescence (OSL) dosimetry. First, detailed characterization of MgB4O7:Ce,Li, shown in literature recently as a potential OSL material, was ... -
First-principles study of electronic properties of one dimensional nanostructures
Li, Junwen (, 2010-05)Scope and Method of Study: -
Low-power and high-performance SRAM design in high variability advanced CMOS technology
Ataei, Fatemeh (2017-05)As process technologies shrink, the size and number of memories on a chip are exponentially increasing. Embedded SRAMs are a critical component in modern digital systems, and they strongly impact the overall power, ... -
Optically stimulated luminescence and signal stability of magnesium borate doped with gadolinium-lithium
Downey, Aaron (2015-05-08)This paper explores the effects of codopance with lithium using the gadolinium metal from the lanthanide series. The embodied work include an analysis on a material's ability to capture and hold a 'signal' — or a radio-receptive ... -
Phase Diagrams and Quantum Phase Transitions in Lattice-Confined Antiferromagnetic Spinor Bose-Einstein Condensates
Tang, Tao (2018-12-01)A spinor Bose-Einstein condensate (BEC) confined in optical lattices has attracted much attention for its abilities to systematically study, verify, and optimize condensed matter models. In this dissertation, I present ... -
Role of cosmic rays in lightning initiation
Lindy, Nathan Carl (2014-07)From electric field measurements, the maximum electric fields typically found within a thunderstorm are an order of magnitude too weak to initiate a lightning discharge. Relativistic electrons produced in galactic cosmic ... -
State dependence of quantum ratchets
Ni, Jiating (2017-05)This dissertation reports on the experimental investigation of quantum state evolution using the atomic-optical quantum delta kicked rotors (AOQDKR) with a Bose- Einstein condensate (BEC) of 87Rb atoms. To achieve the ... -
Synthesis, reactivity, and catalytic studies of transition metal complexes of chelating cyclic and acyclic diaminocarbene ligands
Wanniarachchi, Yoshitha Anju (2008-12)Since the first report of a stable diaminocarbene by Arduengo in 1991, carbene ligands have been widely explored in organometallic chemistry due to their favorable features in catalysis. In order to find broad applications ... -
Transport and resonances in kicked Bose-Einstein condensates
Talukdar, Ishan (2010-12)Scope and Method of Study: A purpose of this research was to study the scaling behavior of resonances of a periodically kicked quantum system. Specifically, a model known as a quantum delta-kicked rotor (QDKR) was implemented ... -
