Relaxation of twist helicity in the cascade process of linked quantum vortices.
By numerically solving the three-dimensional Gross-Pitaevskii equation we analyze the cascade process associated with the evolution and decay of a pair of linked vortex rings. The system decays through a series of reconnections to produce finally three unlinked, unfolded, almost planar vortex loops. Total helicity, initially zero, remains unchanged throughout the process. The gradual transfer f...
متن کاملCascade process of linked quantum vortex loops
Here we present for the first time a detailed study of the cascade process of two linked quantum vortex loops under the Gross-Pitaevskii equation. After a series of successive reconnections the vortex system decays to three distinct loops. Kinetic helicity as well as various geometric and topological properties associated with helicity are examined throughout the reconnection events, providing ...
