Hint: don’t believe everything you see on social media.

LK-99 has been touted as a potential room-temperature superconductor that could revolutionize fields like energy and transportation. However, many experts are skeptical as the initial research papers have not been peer-reviewed and contain inconsistencies and imprecisions. Early attempts to replicate LK-99 have had mixed results, with some samples showing signs of diamagnetism but not conclusively proving superconductivity. Even if LK-99 does turn out to be a room-temperature superconductor, significant challenges around manufacturing and engineering would remain before it could be utilized in real-world applications. Many experts believe that more incremental improvements to existing superconductors may be a more practical path forward for now.

    Here’s what the experts think:

    • Condensed Matter Theory Center of the University of Maryland about the original paper:

      “Physics” being presented in these unrefereed preprints is a travesty. The original paper has no obvious SC transition and the T< T_c resistivity is 100 times that of Cu. Southeast also has no transition, just instrumental artifacts. What is the goal here? No one can fool nature

    • Condensed Matter Theory Center of the University of Maryland about a claimed replication:

      Very helpful @QM_phys_kyoto (thans) points out that Southeast may have drawn their figure misleadingly. On a linear scale, there seems to be no transition, very disappointing and not a good sign since the artifact also looms large

      CMTC has high standards and we are exhausted
