Squeezed bipolaronic states and high temperature superconductivity in BaLaCuO systems

Abstract

The Bose condensation of real-space electron-pairs (the so-called ‘Bipolarons’) occur if at all, at extremely low temperature because of the extraordinarily high effective mass of the conventional Bipolarons. In this communication, we point out that peroxide bonding of the typeO -Cu +O - occur readily in the high temperature superconductive oxides. and may be responsible for its superconductivity. We generate these pairs through “Squeezed” two-photon operators. The resulting polarons and bipolarons should be properly called squeeps and bisqueeps, to distinguish them from conventional polarons and bipolarons. The peroxide bisqueeps will have low effective mass and can undergo Bose-Einstein condensation at high temperatures.
