Quantum Tornadoes in Stirred Superfluids (3 of 3)

Caption

(A to D) Two vortex lines approach each other, connect at two points, form a ring and exchange between them a portion of the vortex line, and subsequently separate. Segment (a), which initially belonged to the vortex line attached to the wall, is transferred to the long vortex line (b) after reconnection and vice versa. This image relates to an article that appeared in the June 10, 2011, issue of Science, published by AAAS. The study, by Dr. Aurel Bulgac of University of Washington in Seattle, Wash., and colleagues was titled, "Real-Time Dynamics of Quantized Vortices in a Unitary Fermi Superfluid."
