What is the thermal conductivity of the superfluid component ofHelium II. Wikipedia claims that it is infinite, but I don'tbelieve that. I base my believes mostley on experiments regardingsuperleask (I haven't done any of those myself, but I've read aboutthe work of others) In these experiments two bodies of Helium IIare connected through a very narrow path, the path is so narrow itonly allows the super component of Helium II to pass. When one ofthe two bodies is heated you'll see that there will be atemperature difference and a pressure difference.
From what I understood super components of Helium II from the coldbath shall travel to the warmer bath so that both baths have thesame concentration of super components. This combined withwikipedia's claim that the conductivity of the super components areinfinite possses a problem for me. For if the conductivity isinfinite how can there be a temperature difference? But regardlessof this problem (I can think a way around this). Thesupercomponents would need to travel at the speed of light to makesure that both baths have the same concentration of supercomponents.
Hope someone can help me with this.
