Hey everyone,
As a few of you may know, there was a paper released a few days ago claiming that an Room-Temperature Ambient-Pressure Superconductor (RTAPS) was created. You can see the original paper here: https://arxiv.org/abs/2307.12008
To bring things into perspective if this holds true we would likely dispense with energy and transportation concerns. It would be akin to the discovery of fire, penicillin or the transistor. A groundbreaking change. See here for a more detailed, bullish list of things it can help with: https://nitter.net/Andercot/status/1685088625187495936
There are many communities that are discussing this. The best summary I was able to find is here: https://forums.spacebattles.com/threads/claims-of-room-temperature-and-ambient-pressure-superconductor.1106083/page-17
There is still a very much active debate there (and elsewhere online) of people on the viability of the original people. Many are pessimistic that the evidence is scant and that the original publication does not hold its water. An interesting summary of the sentiment of a part of the community can be found through the (faux) betting market of Manifold here: https://manifold.markets/QuantumObserver/will-the-lk99-room-temp-ambient-pre
On the link above they are also diligently tracking any replication attempts. Currently we are at the stage were theoretical simulations have validated the possibility of the purported materials to be superconductors (https://arxiv.org/abs/2307.16892).
Finally, a nice replication attempt that tried to make the creation process better and demonstrated some of the effects required to prove superconductivity (scroll up): https://twitter.com/iris_IGB/status/1685804254718459904
This is very exciting, because even if some properties are valid, it gives a mjor boost to the whole field.
