Creator:: Matthews, Bethany E.
Abstract:: Learning about periodic and oscillatory systems is a huge step in an undergraduate's comprehensive understanding of physics and complex systems such as solids. However, understanding how specific changes to such a system affect aspects of the entire system can be difficult. The goal of this study is to create a...

Creator:: Walsh, Kenneth Charles
Abstract:: Electronic structure calculations for free and immersed atoms are performed in the context of unrestricted Hartree-Fock Theory. Spherical symmetry is broken, lifting de-generacies in electronic conﬁgurations involving the magnetic quantum number m. Basis sets, produced from density functional theory, are then explored for completeness. Com-parison to spectroscopic data is done...

Creator:: Griffiths, Scott T.
Abstract:: Future satellite missions like NASA’s upcoming Magnetospheric Multiscale (MMS) mission are targeting reconnection diffusion regions at the Earth’s magnetopause. These diffusion regions are small compared to the total surface area of the magnetopause. Furthermore, the location of the diffusion region depends on external parameters such as the current state of...

Creator:: Smith, Christopher S.
Abstract:: Our research was focused mainly on the field of plasma physics and the creation of plasmas in a laboratory environment. We first began our project with the goal to develop a tabletop Tokamak, a doughnut shaped device that magnetically confines plasmas at pressures greater than one atmosphere. After researching this...

Creator:: Sanders, JC
Abstract:: The large population of 2r>100m near earth objects (NEOs) presents a certain hazard to life on earth. It has been proposed that a nuclear device may be used to alter the course of such objects, thereby averting a catastrophic collision with the earth. The asteroid interdiction problem includes a number...

Creator:: Rogers, Michael
Abstract:: Contamination events at Oak Creek, which runs through Oregon State University Research lands, prompted investigations into alternate transport mechanisms for moving liquid effluent from OSU Diary lands to Oak Creek. Magnetometer surveys conducted at the Diary identified magnetic signatures spatially associated with sub-surface locations of drain tiles, a 12-inch pipe,...

Creator:: Song, Jung-Hwan
Abstract:: Immersion energies for an impurity in a homogeneous electron gas with a uniform positive background charge density have been calculated numerically using density functional theory. The numerical aspects of this problem are very demanding and have not been properly discussed in previous work. The numerical problems are related to approximations...

Creator:: Dorsett, Skye Forrest
Abstract:: Total electronic energies are calculated numerically for free and singly-ionized He, Li, C, and Ne atoms using density functional theory. Immersion energies are calculated for a single C impurity atom embedded or absorbed into a charge-neutral system composed of a free-electron gas with uniform positive background, also called 'jellium'. Nonspherical...
