Absolutely incorrect.
Superconductivity occurs because two electrons pair off. This transforms fermion behavior into boson behavior: Fermions obey the exclusion principle; bosons do not. As bosons, they fall into approximately the same low energy state, which allows them to flow without resistance.
The question is how on earth the electron coupling is occuring: At room temp, normally vibrations would overwhelm all of the known mechanisms of superconductivity.
- eykanal 14y agoI'm aware of the definition of superconductivity. My point is that these researchers have no definitely found superconductivity, they have found evidence that under controlled conditions they can possibly achieve short-term high-temp superconductivity. This is a huge accomplishment, to be sure, but it's not as simple as "room-temperature superconductivity."
