超流He-4中干摩擦的可能性
On the Possibility of "Dry" Friction in Superfluid He-4
摘要:
我们提出了在T> T_{c} = 0.5 - 1 K时氦-Ⅱ在壁面上ρ_s耗尽的可能微观解释,并预言了在T < T_{c}时氦-Ⅱ存在“干”摩擦的可能性。这两种效应都与二维旋子的能量比三维旋子的能量小2K有关,因此壁是三维旋子的势阱。
英文摘要:
We propose a possible microscopic explanation of the exhaustion of ρ_s of helium-II on the wall at T>T_{c} = 0.5 - 1 K and predict a possibility of the existence in He-II of the "dry" friction at T < T_{c}. Both of the effects connect with that the energy of the 2D-rotons is 2K less then the energy of 3D-rotons, so the wall is a potential well for the last ones.
