Andrew David Ludlow and Dr. Scott Bergeson, Physics Laser cooling and trapping has become one of the most widespread and successful research tools within atomic physics in the last twenty years. The idea is to “hit” an oncoming atom with photons of laser light, which slow the atom down. Then, using the appropriate magnetic field […]
X-ray Fluorescence/X-ray Diffraction for Forensic Analysis
Brent Kimball and Dr. Larry V Knight, Physics My proposition was to determine the feasibility of using a combination x-ray fluorescence/x-ray diffraction technology (initially designed to identify strictly inorganic compounds) for the analysis of organic molecules. By modifying a mineralogical device created for NASA it is feasible to identify solid organic compounds such as drugs, […]
Optical Modulation of Semiconductor Nanocrystal Transport
Brigham Russell Frandsen and Dr. Bret C Hess, Physics and Astronomy The area of nanoelectronic devices is a rapidly growing field as new devices and techniques are continually developed. This is an important field because it is hoped that devices of this scale will replace the current larger counterparts on computer microprocessors and other components, […]
The Development of an Active Noise Control System for a Small Axial Fan
Kent L. Gee and Dr. Scott D. Sommerfeldt, Physics and Astronomy Axial cooling fans used in computers, projectors, and printers often contribute significantly to background noise levels in both the workplace and classroom because of the distinct and often annoying tones they produce. These tones are principally caused by spatially unsteady flow through the fan, […]
Characteristics of an Infrared, Slitless, Spectroscopic, Emission-Line Galaxy Survey
Jacob Peter Fugal and Dr. J. Ward Moody, Physics and Astronomy Cosmology has always attracted the minds of those who pursue the burning question of how the universe began. Since Edwin Hubble proved not only the existence of galaxies outside the Milky Way but also that the further away they are, the faster they are […]
Spin Current: The Contribution of Spin to the Probability Current of Nonrelativistic Particles with Spin
Philip Du Toit and Dr. Jean-Francois Van Huele, Physics and Astronomy Introductory quantum mechanics texts seldom treat the quantum mechanical probability current for nonrelativistic particles with spin. The procedure for calculating probability current is most often presented in relation to particles described by the Schrödinger equation, that is particles without spin.1 In later chapters, after […]
In Situ Ellipsometry of Surfaces in an Ultrahigh Vacuum Thin Film Deposition Chamber
Joseph S. Choi and Dr. David Allred, Physics and Astronomy As current microtechnology advances toward building nanosize components for computers and aerospace devices, oxidation of thin films can have dramatic effects on the electronic and optical properties of these devices. In order to understand optical properties of thin film materials and their oxides in a […]
In-doping of CdSe Nanocrystals
Dan Allen and Dr. William Evanson, Physics and Astronomy In recent years much research has focused on the characteristics of metal and semiconductor “quantum dots” or “nanocrystals”. Cadmium selenide (CdSe) semiconductor nanocrystals of diameter less than ~10nm exhibit unique quantum mechanical properties not present in bulk materials. CdSe nanocrystals of 2-5nm in diameter photoluminesce brightly […]
Calculating Cold Non-Neutral Plasma Modes Using Finite Difference Schemes in a Non-Orthogonal Coordinate System
Donald M Cannon and Dr. Ross L Spencer, Physics and Astronomy A plasma is a gaseous collection of charged particles. Although the particles move relatively independently, their interactions with each other as well as with externally applied fields result in collective behavior such as waves and turbulence. The complexity of this behavior has been one […]
Simulation of a Quantum Algorithm on a Classical Computer
Brent Kraczek and Dr. Jean-Francois Van Huele, Physics and Astronomy Quantum computation is a recent idea of how to use quantum mechanics to improve computer performance. Although a full quantum computer has not yet been built, a few algorithms have been developed which take advantage of different aspects of quantum mechanics. David Deutsch, one of […]
