This artist's interpretation intends to show small grains of a reference material disappearing or floating away. Also shown are two lasers, red and blue, which represent the two different colored lasers used by our instrument. Also visible are linear molecules of carbon dioxide (collections of three balls), CO2.
A recent blog from previous JILA postdoc Adam J. Fleisher discusses his current work at NIST, focusing on developing artifact-free, SI-traceable measurements of carbon dioxide in the air. You can read the full blog here.
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.
