Argonne National Laboratory is seeking a Postdoctoral Appointee in Lemont, IL. The successful candidate would be part of a dynamic team, working with a group of scientists conducting a wide range of basic research using state-of-the-art characterization and nanofabrication facilities at the CNM. The candidate will primarily be responsible for developing an experimental program that enable generation of photons and electrons vortex beam carrying orbital angular momentum in UEM to bring new degree of freedom of light and electron in the study of light-matter interactions and plasmonics dynamics, and then explore their applications in plasmonics and nanophotonics, ultrafast phase transitions, and quantum. The candidate will collaborate with other members at the CNM and other Argonne Divisions. The candidate will be responsible for disseminating research findings by publishing them in peer-reviewed journals and delivering oral presentations at various professional meetings, conferences, symposia, and seminars. Additionally, they will stay informed about the latest techniques and expertise within related research groups through active engagement and collaborative endeavors.
