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?
To be clear, absolutely no one has replicated zero resistance, which is the only thing that matters for a superconductor.
All of the “successful replications” so far have just been tiny flakes of material moving in a magnetic field. No one has even got it to fully levitate, they all stand on one end, which any ferromagnet would do. One video demonstrated that a flake was not attracted to the magnet, which could rule out ferromagnetism. Even assuming that’s true it could still just be diamagnetic - pyrolytic carbon behaves exactly the same way and it’s not a superconductor.
A university today has successfully replicated and proven 0 resistance. Still a ways to go before a viable commercially available version is developed.
Below 110K. That’s still at least 160K away from room temperature.
Thanks for the link. It’s worth noting that they achieved that at temperatures below 110 Kelvin, and the big breakthrough would be doing the same at room temperature and pressure.
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
It’s not yellow. I can’t wait for E&F to try this
That’s how replication works. It really only takes handful of labs being able to replicate to confirm there is a ‘there’ there. Positive evidence of replication is much stronger than negative evidence.
I am not a scientist but I have really been trying to understand this breakthrough. My understanding is not that room temperature ambient pressure semiconductors have been created. It is that several simulations back up parts of the discovery that would lead to said semiconductors, in some reviews are showing that some of the crystalline structures do successfully resemble what would be needed for superconductivity in super preliminary experiments on a tiny scale. We aren’t going to have magic superconducting wire yet, this is still very much in the theoretical material science phase. Ultimately, specifics around the way the doping has to work are pretty unproven. At this point it looks like things like electron photon interaction is happening as it would need to happen on a scale relevant to similar crystalline structures. LK99 isn’t yet in physical testing in any other labs yet, and any labs that would publish results already wouldn’t be worth listening to because there hasn’t been enough time for peer review.
No. At least once lab has actually synthesized the material and verified its superconductivity. It is not just simulations.
A lab in China synthesized a flake of material that behaves the way a superconductor might under a strong magnet, and a separate lab in China made a flake which showed high resistivity. Neither of those qualify for full validation and point to the fact that synthesis has a lot of unknowns that will require more precise doping methods than we have today. This is likely the start of a research path into doped crystals, a path on which a future discovery WILL lead to better conductors that are easy to make.
Dave Jones of the EEVBLOG recently did an informative and unfortunate video covering this. https://youtu.be/QHPFphlzwdQ

I’ve been following him for years and this video had me very disappointed in him. Very arrogant and condescending of him. I know he did similar videos on solar roadways, but 1. he is knowledgeable on that subject, and 2. the people behind that were clearly scammers wanting funding. Here, this is just an unpunished paper with nothing to gain if it turns out it doesn’t work, yet he still treated them as garbage. God, I wish this turns out genuine if only to make HIM look like a dumbass (not to mention this would be huge).
Some of this stuff seems real, but in the one twitter thread embedded in this article, the person says, “Remember, this is fiction.”
Who?

We’re still in the period of hype where naysayers are put on the shelf in order to push the narrative. Remember solar panel roads?
My money says they have a thin layer of magnet coating a material creating the illusion of the messneir effect. A parlor trick with a very long crafting time. People want it to be true, and there will be conspiracy circles about the government locking down the research.
I hope I’m wrong. But I’m not driving on any solar roads.
Those two things aren’t remotely comparable. Solar roadways are technically totally possible without any new inventions, they are just a fundamentally stupid idea.
The whole point of replication by other groups is to rule out parlor tricks. If it can be replicated by independent labs and even works in simulations, it’s real. That’s why this is a preliminary paper at the moment.
