    this should be at least one small step closer to understand high temperature superconductivity for it eliminates one of the main theories of what causes it, specifically, it eliminates the theory that fleeting fluctuations called charge-density waves (CDWs) are the cause.

    This is good because, as the link says, "The source of this extraordinary phenomenon (high temperature superconductivity) is slowly but surely running out of places to hide."

    I wonder how close present high temp supers have come in terms of the vibrational energy it manages to bypass, as compared to the vibrational energy of stuff at room temp, say 300 kelvin Vs 133 Kelvin, I think that is around the highest temp so far.
