F1.00001: Undergraduate Student Research and Education Program in Space Weather at a Community College Invited Speaker: M. Chantale Damas The Queensborough Community College (QCC) of the City University of New York (CUNY), a Hispanic and minority-serving institution, has been very successful at engaging undergraduate students in space weather research for the past two years. Recently, it received two awards from NSF and NASA respectively to support student research and education in solar and atmospheric physics under the umbrella discipline of space weather. Through these awards, students receive stipends during the academic year and summer to engage in scientific research. Students also have the opportunity to complete a summer internship at NASA and at other partner institutions. Funding also supports the development of course materials and tools in space weather. Student research projects, educational materials and the challenges of engaging students in research as early as their first year at a 2-yr college will be presented [Preview Abstract] |

F1.00002: Reduced-Dimensional Coupled Electromagnetic, Thermal, and Mechanical Models of Microwave Sintering Invited Speaker: Erin Kiley In recent years, sintering of micro- and nanopowders carried out in microwave ovens has emerged as a manufacturing technique with many potential advantages over sintering in conventional ovens, including faster processing, finer microstructure, and---in well designed systems---the potential for vast energy savings. A number of techniques for modeling the physical phenomena involved have been reported, but still, there remain various aspects of this highly complex and strongly coupled sequence of events that warrant more careful treatment in mathematical models and their computer implementations. We review the most crucial of these aspects, including the multiscale nature of this problem both in time and in space, as well as the strong coupling of the multiphysics phenomena it involves, and we demonstrate ways of addressing these issues via a reduced-dimensional model of microwave sintering that simulates the electromagnetic, thermal, and macroscale mechanical problems, together with different types of auxiliary models that rectify the typical absence of experimental data on certain material parameters necessary for use in the macroscale solver by simulating their values, and we present a computational example in one dimension to showcase operation of the model.

F1.00003: Quantum flows of probability and heat Invited Speaker: Ben Schumacher Textbook quantum mechanics uses a "probability current" to establish the "conservation of probability" for an evolving spatial wave function. This idea can be adapted to simple quantum systems with finite-dimensional Hilbert spaces, including open systems that exchange energy and information with their surroundings. Through a series of undergraduate projects at Kenyon over the last few years, we have used probability currents to study heat and work flows in quantum thermodynamic systems, including the tiniest possible heat engines.
