Fermionic condensate research. Scientist working with lasers to create a fermionic condensate, which is a particular state of matter that can arise at very low temperatures. Fermionic particles are atoms containing odd numbers of elementary particles known as fermions. If such atoms are trapped using laser beams and magnets, and supercooled to a few fractions of a degree above absolute zero, the atoms all have the same quantum energy state, and become indistinguishable from each other. They coalesce, behaving as if they were one single 'super atom.' Photographed at the Laboratoire Kastler Brossel at the Centre National de recherche Scientifique (CNRS), Paris, France.
