A possible mechanism of superconductivity in high-T-c cuprates

This paper derives a generic T-c formula by using the long-range phase cohe rence condition in quantum phase fluctuation of the order parameter. Taking the two-local-spin-mediated interaction (TLSMI) proposed by Liu and Chen [ Phys. Rev. B 58 (1998) 8812] as a Cooper pair potential, and the T-c formul a, this paper explains five basic experimental facts in high-T-c cuprates. The aim of this paper is to show that TLSMI is a possible pairing mechanism of superconductivity in high-T-c cuprates. (C) 2000 Elsevier Science B.V. All rights reserved.
