Abstract:A strong polaron pairing model of high-temperature cuprate superconductors is presented. The normal and anomalous one-particle Green’s functions are derived from a system with strong electron-phonon coupling. Self-consistent equation for the superconducting order parameter (Δ) is derived using Green’s function technique and following Lang and Firsov transformations. Expressions for specific heat, density of states, free energy, and critical field based on this model have been derived. The theory is applied to … Show more
“…There are large number of theory and model proposed to explain superconductivity such as magnon model, exciton model, bipolaronic model, model of resonant valance bonds, plasmon model to mention some of them. However a consensus regarding the pairing mechanism of carriers has not been reached among researchers [5,16,20,21].…”
