Abstract:

Under certain conditions, the transition of atomic M-clusters to polar configurations, M -->, M(+/-), may be accompanied by a transition from a weak pseudo-Jahn-Teller effect to a strong one and Py the formation of {[}M](+/-)(JT) vibron centers which differ by an S-boson: two electrons which are paired by an interaction with an {[}M](+)(JT) vibron center and which form a completely filled shell. Hole (or electron) doping or photoexcitation of the lattice of M-clusters leads to the formation of seeds of a new phase: a system of {[}M](+)(JT) and {[}M](-)(JT) centers or an S-boson liquid in a reservoir of {[}M](+)(JT) vibron centers. The copper-oxygen high-T-c superconductors are discussed as an example of such a system.
