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.

【期刊论文】Unified theory of superconductivity in La2-xSrxCuO4 and Sr2RuO4

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.

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.
