Title: 'Vortex Lattices' May Help Explain Material Defects
Description: This set of JILA images shows a rotating Bose-Einstein condensate (BEC) "pinned" to a rotating lattice created with lasers as the shape of the combined "vortex lattice" evolves from triangular (top) to square (bottom). The images on the left show the BEC vortex lattice at low, medium, and high pinning strengths, or optical intensity levels (top to bottom). The corresponding images on the right are computer processed to reveal the structural relationship between the BEC vortex and optical lattice, with red indicating the symmetry of the physical structures (hexagonal/triangular or square).
