Microscopic theory for high-T-c superconductivity

Book chapter, 1999

An understanding of superconductivity in the holes doped cuprates is formulated as resulting from (i) recovery of superexchange interactions at T(spin-gap), (ii) appearance of a holes clustering instability at the T(pseud-gap), and (iii) virtual spin excitations in the AF background mediating the phase coherence among holes cluster resonances producing Off-Diagonal Long-Range Order.
