Superconductor Breakthrough Replicated, Twice, in Preliminary Testing::It's been a rough few days in the condensed matter physics realm following claims of the world's first room-temperature superconductor being achieved. However, work to verify and replicate the results

wait, really? other people have confirmed this might be real? I'm not sure i'm ready for that.. i don't dare hope, you know?

but also, if another unrelated team has demonstrated room-temp Meissner effect, that means this might be true, right?

There was an article yesterday of a team not being able to replicate it, so now I'm confused.

According to the simulation apparently it only works if the copper atoms end up in an unlikely place in the crystal, so fabrication might be unreliable. I recall someone in another thread saying the authors themselves had around a 10% success rate. So other efforts to replicate are likely to see more failures until the fabrication is better understood. Makes sense I guess.

The fact that another team saw something I think is really hopeful, even if it's hard to produce and poorly understood, if there is a room-temp effect then it's only a matter of time before it's studied properly and understood. From there hopefully a reliable method of fabrication can be published.

If there is no effect replicated anywhere then the paper is fraud, but if there's any effect replicated then it's just a matter of study and engineering to figure out what it is. It would be interesting even if it isn't exactly room temp superconductivity.

I understood these were just simulations, no real material produced whatsoever.

Berkley one is simulation, one is a chinese lab that seems to have replicated some of the actual material and confirmed some properties of superconductivity.

someone is tracking a lot of different efforts here: https://www.nextbigfuture.com/2023/07/tracking-lk-99-superconductor-replication-efforts.html

wow

It's not yellow. I can't wait for E&F to try this
