The mechanism for the evolution of the Fermi arc with increasing the temperature in high-T c cuprates has been proposed. We have discussed the electrical resistivity in the normal state and the linear-like decreasing of the spin part of the Knight shift from the large pseudogap, whose corresponding

โฆ Synopsis
Recent angle resolved photoemission experiments by
Kanigel et al., [Nature Physics 2 (2006) 447]
show that the low energy electronic excitations in the normal state of underdoped cuprate superconductors exist on open Fermi arcs which shrink upon cooling, and appear to extrapolate to nodal points at zero temperature. We show that this non-Fermi liquid phenomenon could result from the underdoped normal state lying in the quantum critical regime of a superconductor-insulator transition, and present computational results for the electron spectral function which are in reasonable agreement with the experimental results.

We propose a view of the cuprate superconductors based on strong covalent bonding within the CuO2 planes. This covalent picture was developed from an alternative analysis of some recently reported spectroscopic and transport properties of several high temperature superconductors. In this view, antif
