They hurried and referenced (although only stating that the work is similar) Griffin who published yesterday, so I'm surprised they didn't reference Lai et. al., who also published yesterday with similar conclusions. But it'll be interesting to see what happens. It seems that multiple groups are coming to the agreement that this could theoretically be superconducting. So hopefully people can learn to synthesise it. (we have at least 4 papers now, the two from yesterday, this one and arxiv:2308.00676)

"Electronic structure of the putative room-temperature superconductor [ Pb_9 Cu( PO_4)_6 O ]" (2023) https://arxiv.org/abs/2308.00676 : > A recent paper [Lee {\em et al.}, J. Korean Cryt. Growth Cryst. Techn. {\bf 33}, 61 (2023)] provides some experimental indications that Pb10−xCux(PO4)6O with x≈1, coined LK-99, might be a room-temperature superconductor at ambient pressure. Our density-functional theory calculations show lattice parameters and a volume contraction with x -- very similar to experiment. The DFT electronic structure shows Cu2+ in a 3d9 configuration with two extremely flat Cu…
