1963年，已故的W. F.（“乔”）维南得出结论，部分基于直觉，超流体He中量子化涡线的从头开始产生受到能量势垒的阻碍。我们把这种有先见之明的洞察力的背景下，并回顾随后的理论和实验研究，计算的高度的障碍和验证的结果，通过测量负离子移动通过超流He以上的朗道临界速度。我们讨论了这些结果对其他超流体的影响，包括激光冷却的稀原子气体，以及超流体流体动力学的后续发展。
In 1963, the late W. F. (“Joe”) Vinen concluded, partly on intuitive grounds, that the ab initio creation of a quantized vortex line in superfluidHe is impeded by an energy barrier. We place this prescient insight into context and review subsequent theoretical and experimental research that calculated the height of the barrier and validated the result through measurements on negative ions moving through superfluidHe above the Landau critical velocity. We discuss the implications of these results for other superfluids, including laser-cooled dilute atomic gases, and for the subsequent development of superfluid hydrodynamics.
