New submissions to the thesis/dissertation collections are added automatically as they are received from the Graduate School. Currently, the Graduate School deposits all theses and dissertations from a given semester after the official graduation date. This means that there may be up to a 4 month delay in the appearance of a give thesis/dissertation in DRUM

    The Self-Assembly of Particles with Multipolar Interactions
    (2004-12-17) Stambaugh, Justin John; Losert, Wolfgang; Physics; Digital Repository at the University of Maryland; University of Maryland (College Park, Md.)
    In this thesis, we describe results from investigations of the self-assembly of anisotropically interacting particles. In particular, we focus upon the roles of dipolar and higher order multipolar interactions on the patterns of self-organization. Using an experimental model system of vertically vibrated magnetic spheres, we investigate the e®ects of octopolar and higher order interactions on the pattern of self-assembly. We show that simple theoretical point charge models can be used to provide insight into the underlying causes of the observed phenomena. We also show that such models can be used to better understand the pattern formation in several related physical systems, including biological macromolecular self-assembly and cohesive granular materials.
