LO strong coupling superconductivity theory
Description
A superconductivity theory is set up, which considers the effective retardative attractive interaction mediated by LO phonon under the condition of transition of small polaron into large polaron. It has been discovered that high Tsub(c) superconductivity will be caused in the condition of existence of degenerate high frequency LO phonon spectra. The high Tsub(c) superconductivity of YBaCuO and similar MO systems are caused by the exchange of LO phonon between two Froehlich polarons. (author)
