  • The contact value approximation to the pair distribution function for an inhomogeneous hard sphere fluid

    Creator:
    Lurie-Gregg, Paho
    Abstract:
    We construct the contact value approximation (CVA) for the pair distribution function, g(²)(r₁, r₂), for an inhomogeneous hard sphere fluid. The CVA is an average of two radial distribution functions, which each take as input the distance between the particles, |r₂ −r₁|, and the average value of the radial distribution...

  • Computing Wavefunctions of Silicon Donor Qubits with Density Functional Theory

    Creator:
    Almulla, Yousif Waleed
    Abstract:
    Silicon based quantum computing is an attractive approach to large-scale quantum computation due to the significant success of the modern semiconductor fabrication industry. Despite many advances in silicon quantum computing since its inception in 1998, there remains no software for efficiently designing candidate silicon quantum computing devices. Such a development...

  • Broad Histogram Algorithm Comparison for the Square Well Fluid

    Creator:
    Simpson, Tanner T.
    Abstract:
    Thermodynamic properties of systems are often investigated computationally. Traditionally, thermal physics simulations are limited by their very small energy ranges and slow convergence. Broad histogram algorithms are a class of Monte Carlo algorithms that can explore an entire energy (and temperature) range in one thermal physics simulation: potentially saving months...

  • Consistent Histories Formulation of the Double-Slit Experiment

    Creator:
    Bauml, Benjamin N.
    Abstract:
    The standard interpretation of quantum mechanics (known as the Copenhagen interpretation) divides the world into quantum phenomena and classical observers that perform measurements upon the phenomena. This provides a quite functional framework for calculating probabilities of measurement outcomes, but it lacks the generality necessary for such things as retrodiction, and...

  • Measurement of optical bandgap energies of semiconductors

    Creator:
    Russell, Joshua A.
    Abstract:
    A method for bandgap energy determination using di use re ection is presented and compared to the traditional integrating sphere method. We have found the bandgap energies of ZnO, TiO₂, Cu₂O, Si, SnZrS₃, SnZrSe₃, Sn₂S₃, and BiCuOSe powders with both methods and found they agree within 0.03 eV. We have...

  • Design of an Optical Medium for the Simulation of Neutron Transport in Reactor Component Materials

    Creator:
    Konyndyk, David M.
    Abstract:
    The scattering of optical rays by small spherical particles bears a strong resemblance to the diffusion of fission neutrons in solid materials. This work explores the feasibility of exploiting similarities between these two systems for the purposes of reactor component analysis, education, and outreach. After a brief overview of reactor-environment...

  • Evaluation of Materials for Use in Open-Cycle Magnetohydrodynamic Power Generation

    Creator:
    Bowen, Michael S.
    Abstract:
    Recent interest in oxy-fuel combustion for carbon capture, as well as advancements in technologies such as magnetics, materials, and computational modeling has sparked renewed interest in magnetohydrodynamic (MHD) power generation. The increased temperatures of oxy-fuel combustion versus air-fuel combustion poses a challenge in the selection of materials for plasma exposed...

  • High Temperature Electrical Properties of Ceria-Based Ceramics for Use as Electrodes in Magnetohydrodynamic Power Generators

    Creator:
    Bowen, Michael S.
    Abstract:
    Determining the electrical properties of ceria-based materials is important for their use as electrodes in hot-wall magnetohydrodynamic (MHD) power generators with wall temperatures greater than 1500 ̊C. The electrical conductivity of a material can be used in models for predicting the performance of generator designs. More specifically, the temperature dependent...

  • Geometric reasoning in an active-engagement upper-division E&M classroom

    Creator:
    Cerny, Leonard Thomas
    Abstract:
    A combination of theoretical perspectives is used to create a rich description of student reasoning when facing a highly-geometric electricity and magnetism problem in an upper-division active-engagement physics classroom at Oregon State University. Geometric reasoning as students encounter problem situations ranging from familiar to novel is described using van Zee...

  • Substitution Effects on the Structure and Electronic Behavior of Ternary Precious Metal Oxides

    Creator:
    Flynn, Joshua
    Abstract:
    Due to the high cost of precursor materials, complex oxides of 4d and 5d transition metals are under-studied compared to their 3d counterparts. Recent studies have shown that oxides containing heavier transition metals can exhibit exotic electronic states due to presence of strong spin-orbit coupling. The goal of this dissertation...
