LK-99 is absolutely not Graphene in the lab stage in 2004. Graphene has sound theoretical foundations and has a long track record even in 2004, while room temperature ambient pressure superconductor in 2023 is considered highly speculative in the condensed matter community.It's pretty much at the 2004 graphene in the lab stage. Maybe somewhere in 2050 or 2060 we might exploit room temp superconductors industrially. Still it interesting to follow a long like nuclear fusion and graphene.
LK-99 is also absolutely not like (controllable) nuclear fusion which is more of an engineering challenge rather than a fundamental breakthrough in condensed matter physics.
Not sure why people thinks levitation equates to superconductivity, there are many magnetic toys which demonstrate similar effects. Even the Meissner effect (which wasn't even properly demonstrated) would not be sufficient evidence to conclude LK-99 is indeed a room temperature ambient pressure superconductor.
The material could still be diamagnetic though. This video alone is not proof that LK-99 is superconducting. Virtually any material will levitate in the presence of a strong magnetic field, regardless of the orientation of the magnetic field.
I wouldn't trust this Andrew Cote guy. His interpretation of the theory paper from Lawrence Berkeley National Laboratory was incorrect as well.
Are you referring to this paper? Not sure I fully buy the argument that theoretical results of flat bands strongly implies room temperature ambient pressure superconductors.
