I have just watched a video about this. This is from the same group who claimed similar things in the past and were shown that the data was falsified. They had withdrawn the paper.
So, until this is independently confirmed, I am really skeptical about this.
I saw a tiktok about this that there were two separate papers published within the week as it looks like they were competing to take credit for the achievement, which would be unusual for bunk science.
Not an endorsement by any means, but def paying closer attention than I would have.
You're thinking about the University of Rochester group, which claimed room temperature high pressure superconductivity, and whose work was indeed riddled with fraud. This is a different group which claims room temperature and pressure superconductivity in a totally different material. They're sketchy in different ways, but have not previously been down to be frauds (to my knowledge). At most, a bit cranky in their understanding of the underlying theory. Which is why several groups are keeping an open mind and trying to replicate this.
A: there is minimal theoretic backing for this form of superconductivity.
2: if this is true this is simply the largest case of utter dumb luck in the human species, like finding a convenient pill that makes you immortal, superintelligent, sexy and happy.
But if tests prove there are 0 side effects I'm still going to use the magic pill.
Half our most advanced materials science is in strained lattice, but this would still be incredible.
