Andreev reflection, familiar in superconducting systems, shows a much more extensive set of behaviors in the p-wave condensate of superfluid 3He. We discuss the basic ideas of Andreev reflection in the superfluid and its various manifestations. The fact that the process displays almost perfect retroreflection allows us to exploit the remarkable properties of the phenomenon for characterizing the pure quantum turbulence that can exist in these condensates. Finally, we discuss Andreev-reflection “optics” as a means of visualizing this turbulence in real time through the vortex video camera.

超流体3He中的安德烈耶夫反射:量子湍流的探究
在超导系统中很熟悉的安德列夫反射在超流体3 He的p波冷凝物中表现出更广泛的行为。我们讨论了安德列夫反射在超流体中的基本思想及其各种表现形式。该过程显示出几乎完美的逆向反射,这一事实使我们能够利用现象的显着特性来表征可能存在于这些冷凝物中的纯量子湍流。最后,我们讨论了Andreev反射“光学”,作为通过涡流摄像机实时可视化这种湍流的一种方法。
