超流~ 3 He和~ 4 He的表面波

Surface Waves on Superfluid 3He and 4He

M. S. Manninen, J. Rysti, I. A. Todoshchenko, J. T. Tuoriniemi

摘要:

超流3 He和4 He的表面波进行了检查的前提下,这些无粘介质将代表理想的实现这个流体动力学问题。在3 He上的工作是同类工作中的第一个,但在4 He上,可以产生更完整的数据集,以便与理论模型进行有意义的比较。大多数测量都是在零温度极限下进行的,这意味着4 He的T < 100 mK,3 He的T约为100 μK。几十个表面波共振,包括多达11个泛音,观察和监测的液体在细胞中的深度是不同的。尽管有丰富的数据,完美的协议与构建的理论模型不能实现。

英文摘要:

Surface waves on both superfluid 3He and 4He were examined with the premise, that these inviscid media would represent ideal realizations for this fluid dynamics problem. The work on 3He is one of the first of its kind, but on 4He it was possible to produce much more complete set of data for meaningful comparison with theoretical models. Most measurements were performed at the zero temperature limit, meaning T < 100 mK for 4He and T ~ 100 μK for 3He. Dozens of surface wave resonances, including up to 11 overtones, were observed and monitored as the liquid depth in the cell was varied. Despite of the wealth of data, perfect agreement with the constructed theoretical models could not be achieved.
