Phys. Rev. Lett. 71, 1375–1378 (1993)Vortex reconnection in superfluid heliumReceived 16 February 1993; published in the issue dated 30 August 1993 A useful physical model for superfluid turbulence considers the flow to consist of a dense tangle of vortex lines which evolve and interact. It has been suggested that these vortex lines can dynamically reconnect upon close approach. Here, we consider the nonlinear Schrödinger equation model of superfluid quantum mechanics, and use numerical simulation to study this topology changing core-scale process. Our results support the idea that vortex reconnection will occur whenever filaments come within a few core lengths of one another. © 1993 The American Physical Society URL:
