That report of a room-temp, ambient pressure superconductor is amazing

Singularity.For the first time in the world, we succeeded in synthesizingthe room-temperature superconductor (Tc 400 K, 127 oC)working at ambient pressure with a modified lead-apatite (LK-99) structure.A material called LK-99®, a modified-lead apatite crystal structure withthe composition (Pb10-xCux(PO4)6O (0.9<x<1.1)), has been synthesizedusing the solid-state method. The material exhibits the Ohmic metalcharacteristic of Pb(6s1) above its superconducting critical temperature,Tc, and the levitation phenomenon as Meissner effect of a superconductorat room temperature and atmospheric pressure below Tc.Alex Kaplan @alexkaplan0Making frozen coffee @cometeer Prev @PrincetonPhysAlex Kaplan @alexkaplan017hToday might have seen the biggest physics discovery of my lifetime.

There is something here for sureAte-a-Pi @8teAPi1hIt’s real. He’s putting his name on the line. Basically saying thepapers are crap, the team has infighting.. probably over credit. The 3man paper hit arxiv 2.5 hours before the 6 author paper. He’ll assistother groups in verifying.

We have an extremely roughunderstanding of High Tc superconductivity in cuprate-like lattices.It is fully possible we are seeing new physics (albeit shoddilyconducted/hastily published) that doesn't exactly match previousmaterials.2115Alex Kaplan retweetedAnatoly Vorobey @avorobey4hReplying to @alexkaplan01574Alex Kaplan retweetedAlex Kaplan @alexkaplan023mReplying to @alexkaplan0 @condensed_the @sandersted @jjaron @Dereklowe@mattwridley @kchangnyt @DrCarpinetiSounds like serious drama btw Kim and the other researchers.
