Bound clusters and pseudogap transitions in layered high-Tc superconductors

We show that negatively charged dopant ions in hole-doped, layered, high-Tc superconductors induce at low doping bound clusters of four holes in CuO layers. This phenomenon requires double degeneracy of the hole band provided by the anti-Jahn-Teller effect, where dopant ions push apical oxygen ions...
