This research project studies complex multielectron effects in isolated atoms and molecules. The study helps explore the overlap between atomic and condensed matter physics, particularly the usage of atomic physics to learn about many-body phenomena. Multielectron effects constitute many-body problems in atomic systems. However, the multielectron problems have not been traditionally appreciated in AMO physics since most problems in atoms and molecules can be understood through the single-independent- electron picture. Multielectron effects, however, become noticeable when atoms or molecules are exposed to an intense electromagenetic field. In this project, the PIs team has made significant progresses in studying multielectron correlation effects in atoms and molecules in strong laser fields. These results allow us gain further understanding in many-body concepts, which may shine light to many correlated electron problems in condensed materials that are strategically important to Air Force Scientific Research. Tangentially. we have recently created a femtosecond laser processing technique to transform highly reflective metals to a nearly perfect light absorber or only selectively absorbing a certain color of light.
