Deborah L. Paulson and Dr. Ross L. Spencer, Physics and Astronomy When a cloud of charged particles is contained in a Penning Trap, it can be observed to flatten into a disc. The measurement of physical properties of these pancake-like plasmas, such as density and temperature, is difficult or impossible without destroying the plasma in […]
Examining Photocatalysis in TiO2
Daniel Jensen and Dr. Brett Hess, Physics and Astronomy Quantum mechanics is a branch of physics that is used to explain the physical properties of small molecules, nanoclusters, and other atomic systems. The principal equation used in quantum mechanics is the Schrödinger equation and its solution for a particular system tells us everything that can […]
Nanoscale Construction of a Novel Solar Cell Using Vertically-aligned Carbon Nanotubes
David Hutchison and Dr. Robert Davis, Department of Physics and Astronomy We had planned on using the process outlined in the proposal for construction of a supercapacitor and solar cell, but decided to focus our energies on the solar cell idea since we thought we could make faster, more significant progress in that direction. We […]
Oxidation Effects on the Optical Constants of Heavy Metals
Amy Grigg and Dr. Steve Turley, Physics and Astronomy This paper examines a method that takes oxidation gradients into consideration when determining optical constants from reflectance and transmission measurements. The oxidation gradients were measured by two techniques using x-ray photoelectron spectroscopy: sputtering, where data are taken at various depths in the sample after removing the […]
Modeling Magnetized, Differentially Rotating Neutron Stars
Jared Greenwald and Dr. Eric Hirschmann, Physics and Astronomy There has been a tremendous research effort in trying to understand observed astrophysical phenomena. The difficulties in studying the formation of and interactions between astrophysical objects have led to the use of computational methods to solve these problems. From a theoretical point of view, one difficulty […]
Applications of Interferometry
Daniel Christensen and Dr. Dallin Durfee, Physics and Astronomy Our research group is currently building a highly precise and stable atom interferometer/ atomic time standard. This is an atomic clock which, among other capabilities, will enable precision measurements of fundamental constants. Some of the long term goals of this project include time rate-of-change measurements of […]
Broadband Photometric Reverberation Mapping with Meter-Class Telescopes
Carla June Carroll and Professor Michael D. Joner, Department of Physics and Astronomy Introduction The environment surrounding supermassive black holes in active galaxies is very difficult to probe. The physical size of the region of interest can usually fit within our solar system, yet is hundreds of thousands of light years away. It can, however, […]
GENERATION OF TERAHERTZ RADIATION: A METHOD OF STUDYING CHARGE CARRIER MOBILITY IN CONDUCTING SOLIDS
Steve Summers and Dr. Bret C. Hess, Physics and Astronomy Electrical processes within conducting solids happen on the order of a few femtoseconds (femto = 10 ) which is much too short for conventional -15 electronic equipment to be used for analysis. However, as we enter the age of faster electronics, it has become necessary […]
A Dual Stage Laser Ablation Source for Cold Atoms?
Sheng Lee and Dr. Scott Bergeson, Department of Physics and Astronomy Our experiment tested the method of producing sub-thermal atomic beams using a back-illuminated laser ablation target suggested in a recent publication. Creating a sub-thermal atomic beam has a lot of potential for researching fundamental physics. After reading and discussing several articles in the field […]
Solving Rubens’ Flame Tube
Michael Gardner and Dr. Kent L. Gee, Physics and Astronomy The Rubens flame tube is a teaching demonstration that is over 100 years old that allows observers to visualize acoustic standing wave behavior1. Flammable gas inside the tube flows through holes drilled along the top, and flames are then lit above. The tube is closed […]
