This comment intrigued me, so I pulled together some information. The first paper submitted is titled "The First Room-Temperature Ambient-Pressure Superconductor." It lists three authors: Sukbae Lee, Ji-Hoon Kim, and Young-Wan Kwon. Its timestamp is Saturday, July 22, 2023 at 07:51:19 UTC. [1] The second paper submitted is titled "Superconductor Pb10−xCux(PO4)6O showing levitation at room temperature and atmospheric pressure and mechanism." This paper lists six authors: Sukbae Lee, Jihoon Kim, Hyun-Tak Kim, Sungyeon Im, SooMin An, Keun Ho Auh [2]. Its timestamp is Saturday, July 22nd, 2023 at 10:11:28 UTC, or two hours and twenty minutes after the first paper. In both papers the first author is Sukbae Lee and the second author is Jihoon Kim, and in both their affiliation is given as "Quantum Energy Research center, Inc." in Seoul. The first paper posted has Young-Wan Kwon as third author. The second paper does not have Young-Wan Kwon as an author, and has four additional authors with various affiliations. The second paper appears to have been was prepared in LaTeX, and the first paper appears to have been prepared in Word. The title and abstract of the first paper explicitly claim the creation of the world's first room temperature and pressure superconductor. The title and abstract of the second paper don't explicitly claim demonstration of the first superconductor, though they use some terminology that sounds like superconducting properties. The accusation is that Young-Wan Kwon published the first paper without the consent of the rest of the LK-99 team, listed himself as third author, and left off the other four. Two hours later, the rest of the LK-99 team stuffed as much as they had into the second paper, and released it as soon as possible. To me that totally seems like what happened. It explains why there are two different papers from the same group submitted on the same subject on the same day, and it explains why the author lists are different between the two. I haven't yet looked in detail, but I'm betting it also explains a lot of the oddities that people have noted in the first two papers. This also makes me way more excited about the possibility these claims are legit. The information so far is consistent with a research group that was forced to publish early, and who produced a superconductor through a fabrication process that is a bit tricky. There's nowhere near enough evidence to conclude LK-99 is a room temperature superconductor. But one failed replication doesn't prove LK-99 isn't a superconductor - if the fabrication process is finicky we'd expect to see a few dozen failed reproductions and a few successful reproductions [1] https://arxiv.org/abs/2307.12008 https://arxiv.org/abs/2307.12008 [2] https://arxiv.org/abs/2307.12037 https://arxiv.org/abs/2307.12037
