Future Nobel Prize in the making?:

Sounds like Nobel level material here.

I didn't realize just how subtle and weird the properties of superconductors are until I saw this video:

you have to look at the part from 2:51 to 5:17 before you see what I mean.

Thanks for the link, I have read the Nature Physics article that is mentioned in the link. Interesting stuff, though I wouldn't immediately say this is Nobel Prize material (and apparently the editor of Nature agreed, otherwise this would be a Nature paper for sure, instead of a Nature Physics article).

Don't know how significant that is in helping us to understand how high-temperature superconductors work.
It basically suggests that phonons have little to do with it.

I have some questions:

As far as I am aware, all reasonably high-temperture superconductors have at least one heavy chemical element ( and usually a rare one )
But why?
Does a high-temperture superconductor generally require a heavy chemical element ( lets here define a “heavy element” as one with an atomic mass greater than that of iron ) or does having a heavy chemical element makes it more likely to work and, if either of those things are so, why so?
Is there any special reason why a heavy element can increase the maximum temperature of the superconductivity? And, if so, why?

-I tried Googling this but got nowhere.
