An Atomic Game of Duck, Duck, Goose

Selected atoms (green) within doubly occupied sites of a 2D "Fermi Sea" are excited by a polarized laser pulse. Pauli blocking prevents decay of the excited atoms (red) as they can only decay into unoccupied sites (black).

Running in a Quantum Corn Maze and Getting Stuck in the Dark

Comparison of 2-level and 6-level atom decay paths. For 6-level systems, each state can potentially decay into several states and some of them might be dark due to destructive interference.

Electrifying Molecular Interactions

About Our Sponsor: The National Science Foundation (NSF)

Physics Frontiers Centers (PFCs)

NSF logo.The Physics Frontiers Centers (PFC) program supports university-based centers and institutes where the collective efforts of a larger group of individuals can enable transformational advances in the most promising research areas. The program is designed to foster major breakthroughs at the intellectual frontiers of physics by providing needed resources such as combinations of talents, skills, disciplines, and/or specialized infrastructure, not usually available to individual investigators or small groups, in an environment in which the collective efforts of the larger group can be shown to be seminal to promoting significant progress in the science and the education of students. PFCs also include creative, substantive activities aimed at enhancing education, broadening participation of traditionally underrepresented groups, and outreach to the scientific community and general public. Read more about this program at the NSF website.
