摘要：

We discuss the effects of a quantum critical point located nearby optimum doping and related to local charge segregation (stripe phase). The fluctuations in the critical region produce at the same time a strong pairing mechanism and a non-Fermi liquid behavior in the normal phase above the superconducting critical temperature. Superconductivity is a stabilizing mechanism against fully developed charge ordering. A complete scenario for the cuprates is presented. (C) 1998 Elsevier Science Ltd. All rights reserved.
