125 gev higgs boson mass from 5d gauge-higgs unification

Carson, Jason Carl (University of Alabama Libraries, 2015)

In the context of a simple gauge-Higgs unification (GHU) scenario based on the gauge group SU(3)×U(1)′ in a 5-dimensional flat space-time, we investigate a possibility to reproduce the observed Higgs boson mass of around ...
Accelerated Design of Novel Heusler Compounds for Spintronics Applications

KC, Shambhu (University of Alabama Libraries, 2021)

Material discovery could be defined as the identification of a previously unexplored phases/composition which may exhibit properties that are unique or similar to that of previously explored composition. Historically, this ...
Antineutrino neutral current interactions in MiniBooNE

Dharmapalan, Ranjan (University of Alabama Libraries, 2012)

The antineutrino nucleon neutral current elastic scattering cross section measured at the MiniBooNE experiment is reported. The data set corresponds to 10.1 × 10^20 protons on target which is a world record neutral current ...
Applications of methods beyond density functional theory to the study of correlated electron systems

Sims, Hunter Robert (University of Alabama Libraries, 2013)

The difficulty in accurately treating systems in which electron-electron interactions are the dominant physics has plagued condensed matter physics for decades. Currently, there exist many different computational techniques ...
Assessing and Enhancing Seawater Corrosion Performance of Aluminum Alloy 7075 and 2024 Additive Repairs Produced by Cold Gas Dynamic Spray Deposition

Agar, Ozymandias (University of Alabama Libraries, 2021)

The purpose of this research is to investigate the corrosion behavior of cold sprayed (CS) aluminum alloys 2024 and 7075 in an immersed seawater environment, and improve understanding of CS processing-microstructure-corrosion ...
Atom probe tomography study of wide bandgap semiconductor materials

Dawahre Olivieri, Nabil Farah (University of Alabama Libraries, 2014)

This dissertation focuses on developing atom probe tomography (APT) for semiconductors. APT is quickly gaining interest in the field of material characterization because of its unique ability to provide 3D nanoscale studies. ...
Bacterium E. coli- and phage P22-templated synthesis of semiconductor nanostructures

Shen, Liming (University of Alabama Libraries, 2010)

The properties of inorganic materials in the nanoscale are found to be size- and shape-dependent due to quantum confinement effects, and thereby nanomaterials possess properties very different from those of single molecules ...
Bounds on large extra dimensions from the simulation of black hole events at the Large Hadron Collider

Hou, Shaoqi (University of Alabama Libraries, 2016)

Large extra dimensions were originally proposed to solve the hierarchy problem of the Standard Model (SM) of elementary particle physics. The presence of large extra dimensions dilutes gravity, lowering the Planck scale, ...
Collider phenomenology of heavy neutrinos

Das, Arindam (University of Alabama Libraries, 2016)

The existence of the neutrino mass has been established by the neutrino oscillation experiments. The so-called seesaw extension of the Standard Model is probably the simplest idea to naturally explain the existence of tiny ...
Coupling semi-analytic models and N-body simulations: a new way of making galaxies and stellar halos

McCord, Krista (University of Alabama Libraries, 2017)

Stellar halos give insight into the initial conditions that existed when a host galaxy first formed and provide details on disrupted satellites via their different stellar populations. An algorithm that is computationally ...
Dark matter decays from the galactic center using IceCube-86

Pepper, James Alan (University of Alabama Libraries, 2017)

Most searches for Dark Matter primarily focus on the WIMP paradigm, which predicts dark matter masses in the GeV - 10 TeV range. However, these relatively low energy searches continue to produce null results, possibly ...
Development of a highly sensitive magnetometer with a wide temperature range for the study of heterostructured transition metal-gadolinium alloys

Chahil, Narpinder Singh (University of Alabama Libraries, 2016)

The design, construction, and testing of a highly sensitive magnetometer with a wide temperature range for the study of magnetic phase transitions and the effect of thermal processing on heterostructured magnetic films is ...
Diffuse ionized regions in the vicinity of active galaxies

Darnell, Erin Kay (University of Alabama Libraries, 2011)

Using a sample of 39 Active Galactic Nuclei (AGN), we investigated the incidence of giant ionized clouds in the vicinity of active galaxies. We carried out remote observations of the sample using the Southeastern Association ...
Dust mapping of spiral galaxy disks from the Hubble starsmog survey

Bradford, Sarah (University of Alabama Libraries, 2016)

Dust in spiral galaxy disks plays an important role in observations through its interaction with starlight. While arguments have been made in favor of completely opaque spiral disks as a result of the dust (see Valentijn, ...
Dynamic transport measurements of vo2 thin films through the metal-to-insulator transition

Jones, Joshua Michael (University of Alabama Libraries, 2018)

VO2 is a transition metal oxide material well known for its high magnitude metal-to-insulator transition (MIT) with a corresponding change in crystal structure [1]. At room temperature, VO2 is found in an insulating ...
Electrical studies on nickel ferrites and hybrid organic-inorganic semiconductors

Hannan, Brian (University of Alabama Libraries, 2013)

Electrical characterization measurements are performed on ferrite samples and a hybrid organic-inorganic p-n junction. Impedance and resistivity measurements are performed to investigate conducting properties of nickel ...
Electron tunneling in the tight-binding approximation

Mackey, Frederick D. (University of Alabama Libraries, 2016)

In this thesis, we treat tunneling similar to a scattering problem in which an incident wave on a barrier is partially transmitted and partially reflected. The transmission probability will be related to the conductance ...
Exploring the magnetic phases in dysprosium by neutron scattering techniques

Yu, Jian (University of Alabama Libraries, 2014)

With one of the highest intrinsic magnetic moments (10.6 μ_B) among the heavy rare-earth elements, dysprosium (Dy) exhibits a rich magnetic phase diagram, including a few modulated magnetic phases. Aided by the ...
Fabrication and ferromagnetic resonance study of epitaxial spinel ferrite films for microwave device applications

Pachauri, Neha (University of Alabama Libraries, 2014)

Single crystalline nickel ferrite and lithium ferrite thin films have attracted a lot of research attention recently, because of their unique physical properties for practical applications in next generation technologies, ...
Finding fossil galaxy system progenitors using strong gravitational lensing

Johnson, Lucas Edward (University of Alabama Libraries, 2018)

Fossil galaxy systems have been described as some of the oldest systems in the universe, where the central galaxy has cannibalized most nearby member galaxies over cosmic time. While the progenitors to fossil systems have ...
