Reconnection of Quantum Vortices

Caption: Schematic diagram of two quantum vortices meeting, crossing and exchanging tails -- a process called reconnection. The red and blue arrows represent the direction of vorticity. A new study provides visual evidence that after the vortexes exchange tails and snap away from each other, they develop ripples called "Kelvin waves" to quickly get rid of the energy caused by the connection and relax the system.
