Dynamics of quantized rings and loops after reconnection in superfluid helium

The presented work is devoted to the study of the motion of vortex loops after reconnection in superfluid helium. The helium temperature as well as the initial arrangement of the vortex loops varied. The data on the change in the length, average radius of curvature and velocity of vortex loops from the moment of reconnection to the moment of their collapse were obtained. A comparative analysis of the motion of a single vortex ring and a deformed vortex loop was carried out. All calculations were performed within the framework of the vortex filament method using the full Biot-Savard equation.
