KY EPSCoR: FY25: Light-Matter Interactions in Artificial Spin Lattices - Match for 3200005822

Abstract for the original proposal: This DOE EPSCoR Implementation e?ort will enhance energy-related research capability in the EPSCoR jurisdictions of Kentucky and Delaware while building U.S. competitiveness through a national network. The e?ort will ``jumpstart'''' research capability through investments in human resources (assistant professors, research scientists, post-doctoral associates, and graduate students) and technical resources (new and upgraded instrumentation). These participants will unite around the common theme of understanding of how photons, spanning microwave to X-ray energies, interact with arrays of nanoscale magnets called arti?cial spin lattices (ASL). ASLs are a class of metamaterials which exhibit new physical and functional properties based on their structures. A key component of this theme is understanding how ASLs can underpin new, unconventional computing paradigms (e.g. reservoir and neuromorphic). Thus, the program could transform understanding of complex magnetic systems and impact energy-related applications in computing, data storage, and materials characterization. The e?ort will build a network of collaborations among four institutions in the EPSCoR jurisdictions (two R1 and two baccalaureate colleges) and with unfunded partners from non- EPSCoR universities (U. of California Davis and U. of Colorado Boulder) and national laboratories (Berkeley, Argonne, Brookhaven, and Oak Ridge). The e?ort implements a plan for promoting inclusive and equitable research (PIER) which encompasses recruiting, training, and professional development of researchers, and particularly early-stage researchers, from diverse backgrounds. The proposed implementation program aligns with the goals of the DOE O?ce of Basic Energy Science (BES), and speci?cally the X-ray Scattering and Condensed Matter Physics programs in the Materials Science and Engineering division, while aligning closely with e?orts at the DOE X-ray light sources and Nanoscale Science Research Centers. These matching funds support additional equipment acquisition and open access publication costs.
