摘要

This paper derives a generic Tc formula by using the long-range phase coherence condition in quantum phase fluctuation of the order parameter. Taking the two-local-spin-mediated interaction as a Cooper pair potential, and using BCS gap equation and the Tc formula, this paper explains some basic experimental findings of both the high-Tc singlet and the low-Tc triplet superconductors, i.e. La2-xSrxCuO4 (LSCO) and Sr2RuO4, and predicts that the high-Tc superconductivity should also be discovered for extra-underdoped LSCO.

摘要

This paper shows that there should be a second-order phase transition at the temperature T* at which a gap opens in superconductors, and points out the best way to verify this prediction, and that the phase transition might have been discovered more than ten years ago.

摘要

Taking the two-local-spin-mediated interaction (TLSMI) as pairing interaction, this paper explains six important experimental findings in YBa2Cu3O7-δ (Y123), and makes some predictions. The main prediction is that there is very high temperature supercon-ductivity in extra-underdoped Y123.

摘要

This paper shows that exact calculation for the transition probability in quantum mechanics gives rise to breaking the Fermi golden rule, and energy conservation, and gives two examples.
