论文摘要
我们报告了氦4 Superflow的反直觉自加热效果。从根本上，这种不寻常的加热效应与两个不同导体中电流的毛发效应具有现象学相似。它揭示了氦4 Superflow带有热能和熵，这与超富富氦4的两流体模型形成鲜明对比。最近开发的超流体氦4的微观量子理论提供了对这种加热效果的自然理解。
We report a counter-intuitive self-heating effect of helium-4 superflow. This fundamentally unusual heating effect bears a phenomenological resemblance to the Peltier effect of electric current across two different conductors. It reveals that helium-4 superflow carries thermal energy and entropy, which is in contrast to the two-fluid model of superfluid helium-4. A natural understanding of this heating effect is provided by a recently developed microscopic quantum theory of superfluid helium-4.
