Okay, that you could use ultrasound spectroscopy to work on this problem was not something I've read before. So very cool that. But what is more interesting to me is the last bit where they posit that they now know so much about the physics of Sr2UO4 that they may be able work backwards into a more general understanding of super-conductivity, that I find really intriguing. Like many people I bought a sample of YBCO and floated magnets over it when cooled with LN2. And I kept hoping we'd get a reasonable theory that would let us engineer a material that was superconductive at a temperature we could chill without LN2. But years later, here we are. So I'm really hoping this moves us closer to a more complete understanding of the atomic structures that enable superconductivity and how to build them.
