The electron energy spectra of YBa2Cu3O7-δ cuprate superconductor

Taking into account the effects of unperturbed electrons, harmonic phonons, anharmonicities, electron-phonon coupling, and impurities, the electron energy spectrum has been obtained for the representative high temperature cuprate superconductor YBa2Cu3O7-δ, with the help of double-time temperature-d...

Zusammenfassung:Taking into account the effects of unperturbed electrons, harmonic phonons, anharmonicities, electron-phonon coupling, and impurities, the electron energy spectrum has been obtained for the representative high temperature cuprate superconductor YBa2Cu3O7-δ, with the help of double-time temperature-dependent thermodynamic many-body Green’s function theory of electrons. An exceptional feature of the present work crop up with the evolution of pairons and temperature dependent electron density of states (EDOS).
