Support for international workshop on Dynamics of Electrons in Atomic and Molecular Nanoclusters
Abstract
Electron dynamics governs a wide range of important effects in nanoscience. Nanoclusters, as important testbed systems for explorin,g and developing quantum size effects, novel materials, and reaction pathways, exhibit a range of phenomena which are highly sensiti,ve to electron mobility, response, transfer, emission and attachment, direct and exchange interactions, correlations, etc. These eff,ects translate into properties that are of significant interest for fundamental science and for applications. The aim of the present, workshop is to bring together researchers in adjacent fields to examine recent and future developments and to enhance the connectio,n between different branches of research. The program will include invited talks, selected oral presentations, a poster session and,time for individual discussions. A website has been established for the workshop at http://physics.usc.edu/deamn22/. The topics of t,he Workshop are also notable for its relevance to a number of the focus areas of the Naval Research and Development Framework. -An,important property of nanocluster particles is their exceptionally tunable spectral capability. These particles are highly efficient, detectors of electromagnetic radiation, in which by changing their size by just a few atoms, by modifying their structure or compos,ition, or by adding or removing a specific number of electrons, one can in a controlled way alter the frequency, shape and intensity, of the electromagnetic response. These considerations align with the Frameworks interests in multi-domain and multi-spectral senso,rs.-Another key area of interest is that of power generation, energy storage, and energetic materials. Examples that will be discuss,ed at the Workshop, include unusually effective catalytic capabilities of nanoclusters, their chemical reactivity, their potential a,s hydrogen storage media and their utility in enhancing solar cell operation.-Furthermore, studies of nanocluster reaction to high-e,nergy impact, e.g., by high-intensity femtosecond laser pulses, allows one to model at a microscopic level the interaction of materi,als with, say, interference by targeted impulse weapons. Research on these effects will be represented at the Workshop and is relate,d to understanding the behavior of high-performance materials.-As the study of ultracold quantum gases advances from the work with a,tomic condensates to research on trapped molecules, its conceptual and technical overlap with the work on atomic and molecular clust,ers is growing. It is widely recognized that these topics have significant implications for quantum information sciences and for the, development of enhanced precision navigation and timekeeping techniques.-The Navy of course has a substantial interest in understan,ding the operational atmospheric and space environment. Here it should be emphasized that a large number of phenomena involving clim,nodroplets, hydrometeors, microcrystals, and carbonaceous particles. Many of Workshop participants are top experts in the relevant a,spects of chemistry and physics of molecular nanoclusters.-Finally, we would be remiss not to highlight the connection between the w,ork of theorists in the field and the Navys interests in modeling and simulation tools. Many of the invited speakers and other part,icipants are actively involved in developing computational and theoretical approaches to the challenging many-body problems posed by,op with the enumerated focus areas of the Navy Research and Devel,rt and to contribute fruitfully to collaborations between U.S. personnel and the international scientific community.
