The following topics are available for undergraduate research projects. For more information, please contact the college. Members are related to the project.
Adapt the 5 12 photodiode array to become a compact spectral system (Dr. Bernie).
Magneto-optical trap rubidium atoms use diode lasers (Dr. Brecha). Ben johnson is currently engaged in this project. The light and magnetic field emitted by diode laser can capture and limit the evacuation of rubidium atoms in cells. Slow down (cool down) during this process and collect gas samples with reduced temperature? 300,000 to100 MK. Even at these very low temperatures, the sample will not condense because the density is very low.
Spectral oxygen (Dr. Brecha). I have been working on this experiment for several years. Now I'm interested in collecting data on the amount of light absorbed by oxygen at different light wavelengths. The target experiment absorbs the data extracted from the parameters and carries out nonlinear least square fitting. This experiment includes quite a lot of computer work and the work of obtaining data by laser diode system.
Two-photon absorption rubidium (Dr. Brecha). As an extension of my work on oxygen, I have started to set up an experiment, the goal of which is to accurately measure the absolute frequency of light absorbed by oxygen, to some extent as a component of 108. We will use a pair of transition rubidium atoms as our standard range, and we will compare the oxygen absorption function of frequency. The absorption of rubidium is the simultaneous absorption of two different light wavelengths in the two-photon process.
Optically active sugar optical solution (Dr. Brecha). The polarization of polarized light passing through some solutions depends on materials, optical path length and wavelength of incident light. I want to use several diode lasers with different wavelengths (about four), so that a small system can measure the solution of optical rotation characteristics and see if we can determine the concentration and different components with this technical scheme.
Computer interface nonlinear system and computer simulation physical system (Dr. Bernie).
Using sound in science and mathematics teaching (Dr. Erdei). This project is a recent honorary paper. In primary or secondary schools, sound is used as a tool to help teach concepts, behavioral science and mathematics.
The fractal nature of EEG and the relationship between human and music. Human EEG used to use music-producing sounds and short paragraphs of music. The fractal characteristics of EEG, this project will explore this fractal characteristic and its music with fractal characteristics. The relationship between EEG and music can be used in music therapy and other fields.
Mathematical model of random vibration (second generation doctor). When random vibration occurs, it actually increases the signal-to-noise ratio of the signal except noise. This behavior will be discussed in some mathematical models.
Micro-cavity laser based on quantum theory (Dr. Pedro).
Bell Theorem and Quantum Theory (Dr. Pedrotti)
Cavity ring-down spectroscopy (CRDS) (Ph.D. country). Cavity ring-down technology is a very small measure to absorb light. Ring drop measurement is a very important application, for example, in the detection of trace species, people are willing to measure a few molecules in air samples (every 65.438 billion to every trillion dollars). The idea behind this is that CRDS injects pulsed light into the cavity. Once in the cavity, the pulse will slowly leak (because we use a high reflector). By measuring the time required for the pulse to leak out of the cavity or "cycle down", we can determine how many light absorption cavities there are. The amount of absorption may include some molecular absorption cavities. The project includes the establishment of a preliminary ring-down cavity and related data acquisition. Once completed, we will enter the ultra-sensitive mode and use continuous wave laser instead of laser pulse.
Applied Nonlinear Optics (Ph.D.). We use nonlinear optical technology to convert laser frequency into near infrared. Nonlinear frequency conversion is an adjustable process, so a wide spectrum range can cover a single system. We are actively studying the project of further developing tunable light sources. We are also looking for new and novel applications based on tunable light sources.
Using Vanderbilt oscillator to study nonlinear processes and chaos (Dr. Yaney). The project will be a device to study various functions and, if possible, other related physical processes.
A high-precision mathematical or empirical model for fitting the linear function of dye laser to automobile data is established. This also includes making accessories and analyzing data sets (Dr. Yaney).
Laboratory development activities, the establishment of new laboratories (Dr. Yaney). Eventually, this will include building a new laser facility to obtain parametric oscillators for tunable laser systems.
More research opportunities exist in the research institutes of Dayton University, both on campus and at Wright-Patterson Air Force Base. In addition, the higher education of Ohio Southwest Committee also provides many research opportunities. The current admission notice of the Department of Physics.
