| hi temperature superconductivity
the resistance of electron flows decreases as the temperature decreases. But magnetic field intensity also decreases as the temperature increases. Therefore there might be a much more subtle relationship between superconductivity and magnetic field intensity.
the classical theory of superconductors is known as the Bardeen-Cooper-Schrieffer theory (BCS). One of the three features is the formation of Cooper pairs of electrons. But electrons are fermions, which are ruled by the Pauli exclusion principle. But in a state of pairing, somehow the electrons were transformed into boson-like structures. What is it about low temperature that allows electrons to act like bosons?
In outer space, the temperature is near absolute zero, if electrons are found, they must all be in bosonic states. |
