Bardeen-Cooper-Scrieffer, the three who explained traditional superconductivity winning a Nobel prize for it (note that Feynman, who helped explain superfluidity, tried mightily to solve superconductivity, but failed). It is a standard acronym. Since high temp superconductors were first investigated, it has been generally assumed that they need a new theory because key features of the BCS model are missing. This paper reports a measurement that the most characteristic feature of this model is present but disguised, and that there is reason to believe that no new theory is needed. In my view, this is a remarkable result and claim. But this is way outside my expertise. I was hoping people here who know much more about this could comment on the paper’s plausibility and what the judgment of other experts is. If validated, this paper would resolve a decades long mystery in condensed matter physics. I note this paper is published in one of the most reputable peer reviewed journals.Hi Paul:
What does the acronym BCS stand for?
