Interesting, this is being done in room temperature too. I suppose a few things I can conclude from this saga:
1. The synthesis process is much more complex than the original paper suggests. Every group except the original is unable to create a large piece of sufficient purity.
2. It seems like even with a pure sample, the entire structure might not be superconducting which leads it to tilt on one edge instead of completely floating. (Some call it a 1D superconductor, I’m a bit out of my depth here)
Should expect all these things to improve soon, but seems like a genuine breakthrough, not a fake or a dud’
The original group also stated that they are preparing another paper specifically about this synthesis process IIRC. This would seem to indicate that the challenge is known and the initial omission either deliberate or another side effect of this absurdly gripping kdrama.
This 1D stuff really confuses me. I was taught that 1D superconductivity is prohibited by Mermin Wagner theorem. You can induce superconductivity on 1D system but that requires higher dimensional SC near it, which is the opposite of proposed scenario?
If someone have seen theoretical papers explaining this and/or understands it, I'd love to know. Iris Alexandera posted link to some experimental paper [1] but I didn't understand the mechanism from it and it is very scarcely cited
