【期刊论文】THE SOLITARY WAVE MODEL OF SUPERCONDUCTIVITY

In metals and compounds there exist small regions in which the phases of electron-pair waves are coherent. These regions are called superconducting domains (SD). At temperatures lower than Tc, these regions connect with each other and form a superconductor. The electron-pairs are partially bound pairs formed by electromagnetic interactions. Coherence gives rise to solitary waves and the Josephson effect. Ideal conductivity and the Meissner effect follow from these. The different effects of lattice vibrations on low and high-Tc superconductors are explained as well.

【期刊论文】A UNIFIED EXPLANATION FOR SUPERCONDUCTIVITY AND PSEUDOGAP IN YBa2 Cu3 O7-δ

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.
