Do not adjust your picture. This is an example of the snake-like pattern formed when a dipolar Bose-Einstein condensate (blue) separates itself from a non-dipoalr BEC (black). The way in which this separation happens revelas the "hidden structure" inside the gas.
It is widely known that mixtures of Bose-Einstein condensates (BEC's) can "phase separate" under circumstances where the mutual repulsion of the two BEC's overcomes their self-repulsion. Typically, one BEC goes to one side of the enclosure, and the other goes to the other side. Now, along with Chris Ticknor and Eddy Timmermans, Ryan Wilson has expanded this notion to include dipolar BEC's that possess a roton instability. In this case the separation produces fine patterns like the one shown below.
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.
