Master of Science in Physics Plan B Project Papers

Persistent link for this collection

This collection contains some of the final works (Plan B project papers) produced by master's degree students in the Master of Science in Physics graduate program. Please note that students in this program complete either a Plan A (thesis-based) program or a Plan B (project-based) program. Only Plan B project papers are included here; Plan As (theses) can be found in the University of Minnesota Twin Cities Dissertations and Theses collection.

    A Review of Classical and Quantum Optical Trapping of Neutral Particles
    (2023-08-20) Franco, Jonathan W
    The purpose of this report is to briefly explore the forces behind optical trapping of dielectric spheres and neutral particles. For this report, we will be examining two regimes. First, we consider larger dielectric particles classically, and then move briefly into individual atoms quantum mechanically.

    Predicting Microfluidic Droplet Diameters in Glass Capillary Devices Using Machine Learning
    (2023-06) Holte, Serena
    I have successfully generated a graphic user interface that predicts microfluidic droplet diameters from a neural network. The neural network inputs are fluid properties and geometries of 3D glass capillary devices. For water-in-oil single emulsions, the mean-squared error at the end of 100 epochs for training and validation converged to 7.2% and 7.4%, respectively. The deep machine learning model provides an alternative method of predicting droplet size without the need for rigorous theory. Moreover, the model can be altered to predict other microfluidic parameters or properties and could be extended to other fluids as well.

    Analysis of the Potential Hoag-type Galaxy WISEA J234255.19-354810.2
    (2022-07) Swanson, Alaina M
    Ring galaxies are among the most perplexing phenomena we observe in space. Their formation has remained a topic of debate, especially since 1950 when Arthur Hoag discovered Hoag’s Object. Hoag-like objects are exceedingly rare and the ring galaxy WISEA J234255.19-354810.2 has the potential to be the 16th Hoag-type galaxy discovered. I performed two types of data analysis to obtain information about the galactic light profiles. From this analysis, I discovered a very faint bar structure within the core of the ring galaxy, which indicates that WISEA J234255.19-354810.2 is not a Hoag-type galaxy.

    Selective absorption of visible light by a plasmonic gold lattice
    (2021) Nixon, Matthew M
    Simulation, creation, and testing of metamaterial absorber utilizing plasmonic and metal-insulator-metal interactions to create selective absorption of light within the visible spectrum.
