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
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
