dc.description.abstractThe electron-phonon interaction based on the harmonic approximation for phonons is discussed by considering several physical models. Some consequences of this interaction, such as the possibility of cooper pairing and the BCS theory of superconductivity are described. Two proposed mechanisms of High-Tc superconductivity both based on the electron-ion interaction of electron pairing are discussed. A 2D BCS model results the observed values of Tc and the absence of the isotope effect in its conventional form. Another model based on the non harmonic double-well Potentials in the cu-o chain in YBCO is also studied. A qualitative prediction of the effect of pressure on Tc and the smallness of the critical current is made.en_US
