Are there any thermal superconductors? I have a strong feeling this is
a myth started by Larry Niven's mistake in some of his books that
electrical superconductors are thermal superconductors. Of course, I
see nothing wrong the idea of phonons somehow forming coherent pairs
or something similar, but it appears very unlikely.
