Gold-silicide eutectic dynamics of mesotextured materials and their optical properties
(2022-05)
Meso scaled pyramidal and inverse pyramidal structures, hereon referred to as Mesopyramids and Inverse Mesopyramids, are observed on Si[100] post annealing of a tri-layer of gold and silicon thin films. The structures are ...
Quantum walks of a rubidium Bose-Einstein condensate and their applications
(2022-12)
A quantum walk in momentum space with a rubidium spinor Bose-Einstein condensate was recently realized in our research group by applying a periodic kicking potential as a walk operator and a resonant microwave pulse as a ...
Further developments in 2D optically stimulated luminescence dosimetry based on Al2O3 and MgB4O7
(2020-05)
Scope and Method of Study: The objective of this work is to explore potential improvements in 2D OSL dosimetry. These include the introduction of Tikhonov regularization in the pixel bleeding algorithm, which was investigated ...
Searches for beyond the standard model physics in dijet resonances and development of a new b-tagging calibration algorithm at the ATLAS experiment at CERN
(2021-05)
This Ph.D. dissertation describes the development of a new b-tagging calibration algorithm which helps to correctly identify jets originated from b quarks at the ATLAS detector at European Organization for Nuclear Research ...
Power-shift method to control nonlinear systems
(2022-07)
A theoretical technique is developed herein which allows for the experimental access of attractors in a coherent laser with injected signal. This technique is theoretically tested for use in other nonlinear systems such ...
Analysis of measurements and improvements upon the Active Tissue Equivalent Dosimeter
(2020-07)
The Oklahoma State University Radiation Physics Lab is nearing completion in the development of a tissue equivalent proportional counter (TEPC), the Active Tissue Equivalent Dosimeter (ATED), to monitor cosmic radiation ...
Analysis of attractor patterns and behavior for the laser with injected signal
(2022-07)
In this dissertation an understanding of the properties and characteristics of coexisting attractors is discussed. Lyapunov exponent (LE) patterns are shown to be predictors of the dynamics of the laser with injected signal ...
Interfacial effects on the chiral domain walls in ultrathin PT/CO/ALOₓ heterostructures for the futuristic spintronics devices
(2023-05)
Heavy metal /ferromagnet/metal oxide heterostructures are important due to their immense prospects for establishing spin textures such as chiral domain walls which are the basic ingredient of low power and capacious ...
Modeling the ionizing radiation environment in Earth's atmosphere
(2021-05)
The constant bombardment of the Earth by cosmic radiation leads to an atmospheric radiation environment comprised of many species of energetic secondary particle. Aside from carrying out full Monte Carlo simulations from ...
Searches for new physics with top quarks in the final state and measurement of the differential cross-section of ttbar production in association with additional heavy flavor jets
(2022-05)
The Standard Model of particle physics is the most successful theory of elementary particles and their interactions. However, it does not describe some phenomena observed in the experiment, like the presence of dark matter ...
