Reconnections of quantized vortex rings in superfluid ${}^4$He at very low temperatures

P. M. Walmsley, P. A. Tompsett, D. E. Zmeev +1

Collisions in a beam of unidirectional quantized vortex rings of nearly identical radii $R$ in superfluid ${}^4$He in the limit of zero temperature (0.05 K) were studied using time-o…
