THEORETICAL EXPLANATIONS FOR THE HIGH T-C AND THE 8 PROPERTIES OF THEGAP IN THE HIGH-T-C CUPRATES

This paper shows that the observed high T-c, the observed nesting Ferm i surface, and the directly observed eight properties of the gap on th e CuO2 plane in the high-T-c cuprates, including the gap anisotropy, t he zero gap at T < T-c along the direction with an angle 45 degrees fr om the Cu-O bond, the phase difference of the gap between the a-direct ion and the b-direction(a and b are the Cu-O bonds), the multi-gap, th e large ratio of the gap to T-c, the non-BCS-like relation between the gap and the temperature, the decentralization of 2 Delta(0 K)/T-c, an d the finite gap at T = T-c for some experiments, can be explained at the same time by using the common reasonable values for the relevant p arameters in our theory.
